Answer:

Energy is essentially work done by an object or on object.

From,

W = Fd

It's directly proportional to mass.

from,

K. E = 1/2mv²

Energy is directly proportional to mass.

P. E = mgh

Energy is directly proportional to mass.

H = mc∆T

Energy is directly proportional to mass.

Thus increasing mass will increase the energy also imparted on another object since all the above eqns show that relationship.

And for 2 moving bodies

K.Ei = K.Ef(energy conservation)

m1u²1 + m2u²2 = m1v²1 + m2v²2

The relationship is the same that the greater mass the greater the impact.

A short circuit is said to have occurred when two nodes of a circuit at different voltages are abnormally connected

There is said to be a short circuit when; One part of a parallel circuit has a very low resistance and almost all the current will flow through this part and very little current will flow through the other part

The correct option is option B.

Reason:

A circuit has to be closed or the the current path has to be closed for

current to flow. A short circuit occurs when current in a circuit flows

through an abnormal path, such as a bridge in a connection to a load that

creates a parallel path for current flow.

Almost all the current flows through the parallel path due to the low

resistance in the connection (almost zero) and the proximity to the power

source, thereby preventing current from reaching its intended destination

Therefore, the correct option is option B.;

Answer:

23.49m

Explanation:

Distance =  velocity x time

8.7 x 2.7 = 23.49m

The momentum conservation allows to find the final speed of the cars together are:

The momentum is defined by the product of the mass and the speed of the body.

        p = m v

Where the bold letters indicate vector, p is the moment, m is the mass and v the velocity.

If we define the system as formed by the two bodies, the forces during the collision are internal and the momentum is preserved, let's find the moment in two instants.

Initial instant. Before crash.

       p₀ = m v₀₀₀+ m v₀₂

Final moment. After the crash.

      [tex]p_f = 2m \ v[/tex]

The moment is preserved.

      [tex]p_o =p_f \\m v_o + m v_o_2 = 2m \ v[/tex]  

     [tex]v = \frac{m v_o + v_o_2}{2m}\\ v = \frac{1}{2} \ ( v_o + v_o_2)[/tex]

We have two cases:

       v = v₀ / 2

       v = 0

In conclusion using the momentum conservation we can find the final velocity of the cars together are:

Answer:

117,30m

Explanation:

I think the situation here is a horizontal projection to the ground. So in order to find the distance the formula = Ut, where U is the initial speed and t is the Time of flight. To get the time of flight in this case =√2h/g where h is the height and g is gravity. so to get the time = √2×300÷9.81 =7.821 .so range =ut which is equal to the time multiplied by 15m/s =117.30m

Hi there!

To find the total distance traveled, we must find the time taken to fall down.

Ignore the horizontal velocity when dealing with the vertical direction. We can use the simplified equation:

[tex]t = \sqrt{\frac{2h}{g}{}}[/tex]

Plug in the given values:

[tex]t = \sqrt{\frac{2(300)}{9.81}} = 7.821 sec[/tex]

Use the equation:

Δd = vt

Plug in the time and horizontal velocity:

Δd = (15)(7.821) = 117.30m

Finding Kinetic energy with given weight 10kg

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

The work done by the block on the spring and by the spring on the block is 7.22 J.

The given parameters;

Based on law of conservation of energy, the potential energy of the block will be converted to elastic energy of the spring, producing the given extension.

The work done by the block on the spring will be equal to work done on the block by the spring.

[tex]W = \frac{1}{2} kx^2\\\\W = \frac{1}{2} \times 400 \times 0.19^2\\\\ W = 7.22 \ J[/tex]

Thus, the work done by the block on the spring and by the spring on the block is 7.22 J.

Explanation:

Underneath the blade of skates, there is a thin layer of water from the melted ice. ... This water then acts as a lubricant (something whose purpose is decreasing friction), resulting in a smooth motion of the skates over the ice.

The magnitude of the net force exerted by the three astronauts is 84.5 N and the rate at which the asteroid's velocity changes is 0.845 m/s².

The given parameters;

The resultant horizontal force applied by the three astronauts on the asteroid is calculated as;

Fₓ = 35cos(45) + 35cos(45) + 35cos(0)

Fₓ = 84.5 N

The rate at which the asteroid's velocity changes is calculated as;

[tex]F = ma = m\frac{\Delta v}{\Delta t} \\\\\frac{\Delta v}{\Delta t} = \frac{F}{m} \\\\\frac{\Delta v}{\Delta t} = \frac{84.5}{100} \\\\\frac{\Delta v}{\Delta t} = 0.845 \ m/s^2[/tex]

Thus, the magnitude of the net force exerted by the three astronauts is 84.5 N and the rate at which the asteroid's velocity changes is 0.845 m/s².

Hi there!

We can use the derived equation to solve:

[tex]t = \sqrt{\frac{2h}{g}}}[/tex], where:

h = height

g = acceleration due to gravity

Plug in the given values. Remember to CONVERT km to m:

32 km = 32 km * 1000 m / 1 km = 32,000 m

t = √(2(32000)/3.4) ≈ 137.199 sec

Part 2:

Use the derived equation:

vf = √2gh

vf = √(32000)(3.4) = 329.848 m/s
