Linearity is an extremely useful property of equations in physics. If an equation is linear, it allows you to easily add together simple contributions from individual elements to get a solution for a more complex situation. One example of a simple linear equation in classical mechanics is F = ma. If you find the individual accelerations of a particular body due to various individual forces, you can then add those accelerations to find the acceleration due to all of the forces acting together. If Newton's second law were not linear, introductory physics would be a much more difficult and confusing subject!

The schrodinger's equation for [tex](A\phi_1+AU\Psi_1)+(B\phi_2+BU\Psi_2)[/tex] for the particular U and E can be expressed as [tex](A\phi_1+AU\Psi_1)+(B\phi_2+BU\Psi_2)=E(A\Psi_1+B\Psi_2)[/tex].

The solution to the equation is based on Fourier's Eigen Values method. This is the expression for any mathematical function as the sum of an infinite series of other periodic functions. The trick is to find the right functions with the right amplitudes so that when they are superimposed, they give the desired solution.

As a result, the solution to Schrondinger's equation, the system's wave function, was replaced by the wave functions of the individual series, natural harmonics of each other, resulting in an infinite series. Shrodinger discovered that replacement waves described individual states of the quantum system, and their amplitudes indicated the relative importance of that state to the entire system.

The schoringer 's equation is

[tex]-\frac{h^2}{2m}\frac{d\psi^2}{dx^2}+U(x) \psi=E\psi[/tex]

here, the E is the energy of the particle.

since the wave function [tex]\psi_1[/tex] is the solution of the schrodinger's equation,

[tex]-\frac{h^2}{2m}\frac{d\psi_1^2}{dx^2}+U(x) \psi=E\psi_1[/tex]

Since, the wave function [tex]\psi_2[/tex] is the solution of the schrodinger's equation,

[tex]-\frac{h^2}{2m}\frac{d\psi_2^2}{dx^2}+U(x) \psi=E\psi_2[/tex]

Then,

[tex](A\phi_1+AU\Psi_1)+(B\phi_2+BU\Psi_2)=(A(-\frac{h^2}{2m}\frac{d\Psi_1^2}{dx^2})+AU\Psi_1)+(B(-\frac{h^2}{2m}\frac{d\Psi^2}{dx^2})+BU\Psi_2)\\\\=A(-\frac{h^2}{2m}\frac{d\Psi_1^2}{dx^2}+U\Psi_1)+B(-\frac{h^2}{2m}\frac{d\Psi_1^2}{dx^2}+U\psi_2)\\\\=A(-\frac{h^2}{2m}\frac{d\Psi_1^2}{dx^2}+U(x)\Psi_1)+B(-\frac{h^2}{2m}\frac{d\Psi_1^2}{dx^2}+U(x)\psi_2)\\\\=A(E\Psi_1)+B(E\Psi_2)\\\\=E(A\Psi_1+B\Psi_2)[/tex]

Thus, the schrodinger's equation  for particular U and E can be expressed as [tex]E(A\Psi_1+B\Psi_2)[/tex].

Answers

The amount of labour that gravity does is 28.58J. And the work produced by kinetic friction is -28.58J. A force that acts between moving surfaces is referred to as kinetic friction.

We may determine the slope length or hypotenuse using elementary trigonometry: cos(20) = 2.00. (slope length)

slope length: 2.00 m/cos(20) = 2.13 m

The box covers this distance while moving at a constant speed.

In terms of the forces, the total force parallel to the inclined plane acting on the box is given by the equation: F = W - f = mgsin(20) - f, where f represents friction and W is weight.

Work = Wd = (+13.2N)(2.13m) = 28.58J, which is the amount of work done by the force of kinetic friction.

The force acts in the same direction as the displacement, resulting in work.

The creation of solar systems is explained by the nebular theory. According to the explanation, stars are produced from clouds of interstellar gas and dust, and the term "nebula" is Latin for "cloud." It takes around 100 million years for an undifferentiated cloud to develop into a star system with planets and moons.

The nebular theory proposes the sun and planets formed from a rotating cloud of interstellar gases and dust called a solar nebula

According to the nebular theory, the Sun and all of the plants in the solar system descended from the solar nebula, an interstellar cloud of gases and dust. The term "nebula" itself is a Latin word for cloud. The nebula began to collapse over time, and the centre of the collapse (the central mass) eventually turned into a protostar.

It should be noted that this protostar was distinct from our current star in that it lacked the continuous nuclear fusion process that our stars do now. When nuclear fusion begins in the centre of a protostar, it transforms into a star.

a motorist drives south at 25m/s for 3.00 min, then turns west and travels at 20m/s for 2.60 min, and finally travels northwest at 28m/s for 1.00 min. For this 6.00min trip, find (a) the total vector displacement, (b) the average speed, and (c) the average velocity. Let the positive x axis point east.

Answers

a) D = -4273(x)-2327(y)

b) average speed v = 23.33m/s

c) average velocity V = -13.51m/s  south of west.

In order to find the displacement we have to divide the motion on its X and Y components:

dx1 = 25*2*60min = 3000

dx2 = 30*1*60s/min(cos45) = 1273 m

The total X displacement is the algebraic sum of the movement:

We have to do the same on Y:

dy1 = 20*3*60 = 3600

dy2 = 30*1*60(sin45) = 1273

dy = -3600 + 1273 =-2327m

D=-4273(x)-2327(y)

The angle is given by:

α = arctg(dy/dx)

α = 28.57 degrees

That is 28.57 degrees south of west.

the total displacement magnitude is given by:

D = √{(4273) - (2327)}

D= 4865

The average speed is given by:

evaporation is a cooling process and condensation isquestion 16 options:a cooling process also.a warming process.neither a warming nor cooling process.can not tell with the information given.

Answers

Evaporation is a cooling process and condensation is a warming process.

Condensation is the transition of a region of matter from a gaseous state to a liquid state and the opposite of vaporization. This word most often refers to the water cycle. Condensation is the process by which water vapor becomes a liquid. This is the opposite of evaporation, which turns liquid water into vapor. Condensation occurs in one of two ways. When the air cools to its dew point or becomes saturated with water vapor, it can no longer hold water.

Evaporation is always a cooling process. For evaporation to occur, energy is needed by the liquid molecules that are changing phase into gas. This energy is taken from the surroundings in the form of heat energy. So when evaporation occurs, the temperature of the surroundings will decrease, making evaporation a cooling process.

Condensation occurs when warmer, moist air comes into contact with cooler surfaces such as frames, windows, and other superstructures, or cooler areas inside an insulating shell (where moisture has penetrated the vapor barrier).

Therefore, evaporation is a cooling process and condensation is a warming process.

Determine immediately after impact:
a) The angular velocity of member ABC.
b)The velocity of the sphere.

Answers

(a)The angular velocity v(d)' is 0.936 m/s

(b)The velocity of the sphere is 3 rad/s

Let us assume that

angular velocity of member ABC is v(d)'

velocity of the sphere = ω'

Write the moment of inertia of the member ABC

I(G) = 1/12 ML²

I(G) = 1/12*(2.4)(0.75m)²

I(G) = 0.112 kgm²

After the impact

ω = ω'(ccw)

ν'(G) = (L/4)ω' (upwards)

ν'(A) = (L/4) ω' (downwards)

Take the moments about B

m(d)v(d)(L/4) + 0 = m(d)v'(d)(L/4) + I(G)ω' + Mv'(G)(L/4)

m(d)v(d)(L/4) = m(d)v'(d)(L/4) + I(G)ω' + M(L/4)²ω'

m(d)v(d)(L/4) = m(d)v'(d)(L/4) + ] I(G) + M(L/4)² ]ω'

(0.8)(3)(0.75/4) = (0.8)v'(d)(0.75/4) + [ 0.112 + (2.4)(0.75/4)²

0.45 = 0.15v(d)' + 0.1963ω' -------------------- (eq1)

From the coefficient of restitution,

v(d)' - v(A)' = -e [ v(d) - v(A) ]

v(d)' - (L/4)ω' = -(0.5) [3-0]

v(d)' - (0.75/4)ω' = - 1.5

v(d)' - 0.1875ω' = - 1.5 ---------------------- (eq 2)

From eq 1 and eq 2

v(d)' = 0.936 m/s

A 1500 m
B 500 m
C 1000 m
D 750 m

Answers

After 2seconds of sending sonar, a ship hears an echo. The depth of the sea is 1500 meters if the sound wave speed in water is 1500 m/s.

Let sea depth equal d.

Considering that the sound wave's water speed (v) is 1500 m/s

The sound must travel to the ocean's bottom before being reflected back to the ship, resulting in a total distance of two dimensions for the sound.

Time (t) = 2s for receiving the echo

Total distance traveled times the speed of sound

1500 m/s is equal to 2d/2s = 1500 m.

Consequently, the water is 1500 meters deep.

Wind shear is calculated by finding the difference between the wind speed values at two different heights. Using the wind profile you identified as the ideal environment for a supercell, next you will calculate the 0-1 km and 0-5 km wind shear values. This means we will find the difference between the surface wind (lowest wind barb on the sounding) and the speed of the wind at lkm and 5 km. The atmospheric pressure at 1km above sea level is typically very close to 850 mb. The pressure at 5 km above sea level is very close to 500 mb. Please calculate the 0-1 km and 0-5 km wind shear values in knots (kts). 0-1km shear value 0-5km shear value

Answers

At the surface, the wind speed is between 13 to 17 knots. At 1 km or 850 MB level, the wind speed is between 48 to 52 knots. Thus, the 0-1 km wind shear is (48 -13) or (52-17) = 35 knots.

At 5 km or 500 MB level, the wind speed is between 68 to 72 knots. Thus, the 0-5 km wind shear is (68-13) or (72-17) = 55 knots.

The Bernoulli effect can have important consequences for the design of buildings. For example, wind can blow around a skyscraper at remarkably high speed, creating low pressure. The higher atmospheric pressure in the still air inside the buildings can cause windows to pop out. As originally constructed, the John Hancock building in Boston popped window panes, which fell many stories to the sidewalk below. Suppose that a horizontal wind blows in streamline flow with a speed of 10.5 m/s outside a large pane of plate glass with dimensions 6.00 m Times 1.10 m. Assume the density of air to be constant at 1.20 kg/m^3. The air inside the building is at atmospheric pressure. What is the total force exerted by air on the window pane? If a second skyscraper is built nearby, the air speed can be especially high where wind passes through the narrow separation between the buildings. Solve part (a) again if the wind speed is 21 m/s, twice as high.

Answers

Given,

          Speed of wind v = 10.5 m/s

          Dimension of plate = 6 m times 1.10 m

          The density of air d = 1.20 kg/m³

Therefore,

         F = (1/2)dv²A

         A = 6(1.10)m²           [From dimension]

         F = (1/2)(1.20)(10.5)²(6)(1.10)

         F = 436.59 N

The force on the window pane is 436.59 N.

(a) if the wind speed is 21 m/s

        F = (1/2)(1.20)(21)²(6)(1.10)        

        F = 1746.36 N

The force on the window pane is 1746.36 N.

Answers

If the block's mass is m, block's initial velocity is v and the spring constant is k, the maximum compression in the spring is  sqrt(mv² /k)

Applying the law of conservation of energy, since it is a frictionless surface, all the kinetic energy of the block will be converted to the potential energy of the spring.

The kinetic energy of the block:

Ek = 1/2 . mv²

Where:

m = mass of block

v = block's initial velocity

The potential energy of the spring:

Ep = 1/2 . kx²

Where:

in which of the following cases will there be a current in the ammeter? (1) the switch has just been closed (2) the switch has been closed a long time (3) the switch has just been opened (4) the switch has been opened a long time

Answers

The presence of a current in an ammeter depends on the state of an external electrical switch. If the switch is closed, there will be a current in the ammeter; if the switch is opened, there will be no current in the ammeter. The length of time the switch has been in a particular state does not affect the presence of a current in the ammeter.

The presence of a current in an ammeter depends on the state of an external electrical switch. A switch is a device used to break or make an electrical connection, and can be used to control the flow of electricity in a circuit. In the following cases, the presence of a current in the ammeter can be determined:

(1) If the switch has just been closed, there will be a current in the ammeter. When the switch is closed, it creates an electrical connection, allowing electricity to flow through the circuit, and thus a current to be registered on the ammeter.

(2) If the switch has been closed for a long time, there will still be a current in the ammeter. This is because the switch is still in the closed position, allowing electricity to flow through the circuit, and thus a current to be registered on the ammeter.

(3) If the switch has just been opened, there will be no current in the ammeter. When the switch is opened, it breaks the electrical connection, preventing electricity from flowing through the circuit, and thus no current will be registered on the ammeter.

(4) If the switch has been opened for a long time, there will still be no current in the ammeter. This is because the switch is still in the open position, preventing electricity from flowing through the circuit, and thus no current will be registered on the ammeter.

15. A 5.0 g coin sliding to the right at 25.0 cm/s makes an elastic head-on collision with a 15.0 g coin that is initially at rest. After the collision, the 5.0 g coin moves to the left at 12.5 cm/s. Find the final velocity of the other coin. (12.5 cm/s, Right)​

Answers

Answer: Finally, we can use this value to find the final velocity of the 15.0 g coin. Since velocity is defined as the change in position over time, and the 15.0 g coin is initially at rest, its final velocity must be equal to its final momentum divided by its mass. Therefore, the final velocity of the 15.0 g coin is 187.5 g cm/s / 15.0 g = 12.5 cm/s. Since the 5.0 g coin is moving to the right and the 15.0 g coin is moving

Explanation: To solve this problem, we can use the conservation of momentum. Momentum is a measure of an object's motion and is defined as the product of its mass and velocity. In an elastic collision, momentum is conserved, meaning that the total momentum of the system before the collision is equal to the total momentum after the collision.

We can use this principle to find the final velocity of the 15.0 g coin. First, we need to calculate the initial momentum of the system. The 5.0 g coin has an initial momentum of 5.0 g * 25.0 cm/s = 125 g cm/s. Since the 15.0 g coin is initially at rest, its initial momentum is 0 g cm/s. The total initial momentum of the system is therefore 125 g cm/s.

After the collision, the 5.0 g coin moves to the left at 12.5 cm/s, so its final momentum is 5.0 g * (-12.5 cm/s) = -62.5 g cm/s. Since momentum is conserved, the final momentum of the system must be equal to the initial momentum of the system, so the final momentum of the 15.0 g coin must be 125 g cm/s - (-62.5 g cm/s) = 187.5 g cm/s.

Finally, we can use this value to find the final velocity of the 15.0 g coin. Since velocity is defined as the change in position over time, and the 15.0 g coin is initially at rest, its final velocity must be equal to its final momentum divided by its mass. Therefore, the final velocity of the 15.0 g coin is 187.5 g cm/s / 15.0 g = 12.5 cm/s. Since the 5.0 g coin is moving to the right and the 15.0 g coin is moving
