The planet mercury orbit around the sun is an ellipse eccentricity 0.206 length of major axis us 1.16×10 the power of 8 km. the sun at one focus
1,What is the maximum distance from mercury to the sun
2,what is the minimum distance b/n them

Answers

The maximum distance from mercury to the sun is 0.58 * 10⁸ km.

The minimum distance b/n them is 0.46 * 10⁸ km.

What is the distance about?

The shape of an elliptical orbit can be described by its eccentricity, which is a measure of how "flattened" the ellipse is. An eccentricity of 0 indicates a circular orbit, while an eccentricity of 1 indicates a parabolic orbit.

In the case of Mercury's orbit, the eccentricity is given as 0.206, which means that the orbit is slightly flattened, but still close to circular. The length of the major axis of the ellipse is given as 1.16 * 10⁸ km.

To find the maximum distance from Mercury to the sun (also known as the aphelion), we need to find the distance from the center of the ellipse to the farthest point on the ellipse (which is at the top of the major axis). This distance is equal to half of the length of the major axis. Thus, the maximum distance from Mercury to the sun is:

1.16 * 10⁸ km / 2 =0.58 * 10⁸ km

To find the minimum distance between Mercury and the sun (also known as the perihelion), we need to find the distance from the center of the ellipse to the closest point on the ellipse (which is at the bottom of the major axis). This distance is equal to half of the length of the major axis times the square root of 1 - (eccentricity)². Thus, the minimum distance between Mercury and the sun is:

[tex](1.16 x 10^8 km / 2) * \sqrt{(1 - (0.206)^2) } = 0.46 * 10^8 km[/tex]

Therefore, Note that the sun is located at one of the foci of the elliptical orbit, rather than at the center. However, since the eccentricity of Mercury's orbit is relatively small (0.206), the distance from the center of the ellipse to either focus is very close to the distance from the center to the top or bottom of the major axis, and the difference can be ignored for most purposes.

how much heat transfer (in j) occurs from a system if its internal energy decreased by 300 j while it was doing 16.0 j of work? (enter the magnitude.)

Answers

The system released 134 J of energy into the surrounding while doing 16 J of work.

What is energy ?

The ability to exert a force that causes an item to move is what is meant by the definition of energy as the "power to accomplish work."

We use thermodynamics principles in this situation. There are already obtained relationships for intense properties like internal energy (U), heat transfer (Q), and work (W) that were based on differential equations. The formula is

ΔU = Q + W

But since these factors depend on their signs, we must remember to take them into account. Van Ness, Smith, and Abbott assert that declining has a negative sign convention. If work is being done ON the system, the sign is positive; however, if work is being done BY the system, the sign is negative. in this instance,

ΔU = -150 J

W = -16 J

Then , we can determine Q as follows

- 150 J = Q - 16 J

Q = - 134 J

Thus 134 J of heat of released by the system into the surroundings.

what is the expected mass of a potassium-39 nucleus, based on the total mass of its protons and neutrons?

Answers

The total mass of the protons and neutrons in a potassium-39 nucleus is 6.5307 x 10^-26 kilograms.

The mass of a potassium-39 nucleus can be calculated based on the total mass of its protons and neutrons. Potassium-39 is a stable isotope of potassium with 19 protons and 20 neutrons in its nucleus. The mass of a proton is approximately 1.6726 x 10^-27 kilograms, and the mass of a neutron is approximately 1.6749 x 10^-27 kilograms.

Therefore, the total mass of the protons in a potassium-39 nucleus is 19 x 1.6726 x 10^-27 = 3.18094 x 10^-26 kilograms. The total mass of the neutrons in a potassium-39 nucleus is 20 x 1.6749 x 10^-27 = 3.3498 x 10^-26 kilograms.

The total mass of the protons and neutrons in a potassium-39 nucleus is therefore 3.18094 x 10^-26 + 3.3498 x 10^-26 = 6.5307 x 10^-26 kilograms. This is the expected mass of a potassium-39 nucleus, based on the total mass of its protons and neutrons.

Answers

The reason the frog doesn't slip is the friction between his feet and the board

Friction is the force that opposes the relative motion between two surfaces that are in contact. In the case of a skateboard, the static friction between the feet and the board helps to keep someone from slipping off when the skateboard is not moving. Once the skateboard begins to move, the static friction changes to kinetic friction and helps to keep it from slipping off as the skateboard moves.

The amount of friction between two surfaces depends on the nature of the surfaces and the force with which they are pressed together.

0.00025 N is the magnitude of the net force on the first wire in (figure 1).

What is net force?

The total of all forces exerted on an item is known as the net force. A mass can accelerate due to net force. A body is subject to another force whether it is at rest or in motion. When there are a lot of forces acting on a system, the phrase "net force" is employed.

From the diagram, first wire has an attracting force from third wire at 0.04 m distance and a repelling force from second wire at 0.02 m distance.

Expression of the force is -

F = [µ ×π×(I)² × L] / (2πd)

When d = 0.02 m,

or, F = [4 ×π× 10⁻⁷(10)² × 0.50] / (2π × 0.02)

or, F = 0.0005 N

And when d = 0.04 m,

or, F = [4 ×π× 10⁻⁷(10)² × 0.50] / (2π × 0.04)

or, F =  0.00025 N

sound is emitted by 20 w speaker (which propagates in all directions). what is the intensity in decibels at 10 m? 100m?

Answers

The intensity of sound in decibels at 10 m is 17.6 dB.

The intensity of sound in decibels at 100 m is 14.08 dB.

The formula to calculate intensity when power is given is I = P/A

where, I is the intensity

P is the power

A is the area

Given, P = 20 W

A₁ = 4πr² = 4π* 10² = 1256.64 m²

A₂ = 4πr² = 4π* 100² =125663.71 m²

I₁ = P / A₁ = 20/1256.64 = 0.0159 W/m²

I₂ = P / A₂ = 20/125663.71 = 0.000159 W/m²

The expression between intensity of sound and decibel level is

dB = 10* log (I/ 1.0* 10⁻¹² W/m²) --------(1)

Substituting the values of I₁ and I₂ in (1),

dB₁ = 10* log (1.5* 10⁻²/ 1.0* 10⁻¹²) =  10* log(1.5* 10¹⁰) = 10* [ log 1.5 + 10] = 10*(0.176* 10) = 17.6 dB

dB₂ = 10* log (1.5* 10⁻⁴/ 1.0* 10⁻¹²) = 10* log(1.5* 10⁸) = 10* [ log 1.5 + 8 ] = 10*(0.176* 8) = 14.08 dB

The pilot should head 12.09 degrees clockwise to the west direction.

The actual velocity of plane over ground is calculated to be 410.34 km/hr.

This question can be solved using the concept of resolution of vectors.

Any vector that is oriented at an angle to the horizontal (or vertical) can be thought of as having two parts: the direction vector and the tangent vector, according to the definition of a vector (or components). In other words, any vector with a two-dimensional direction may be conceived of as having two pieces.

a) Let us assume that the plane moves at an angle θ (clockwise to the west direction).

Let the velocity of plane be given by '[tex]v_{a} \\[/tex]'. Now this velocity [tex]v_{a}[/tex] has two components.

Answers

Correct answer is b. at right angles to the direction of wave travel

The vibrations of a transverse wave move in a direction "at right angles to the direction of wave travel." The correct option is B.

What is a transverse wave?

A transverse wave is a type of wave where the particles of the medium vibrate perpendicular to the direction of wave propagation. In other words, the motion of the medium is at right angles to the direction in which the wave moves. The term "transverse" is derived from the Latin word "transversus", which means "across".

Examples of transverse waves include light waves, electromagnetic waves, and seismic S-waves. In a transverse wave, the displacement of particles in the medium is perpendicular to the direction of the wave. This type of wave can be described by its amplitude, wavelength, frequency, and speed.

The amplitude of a transverse wave is the maximum displacement of the particles from their equilibrium position. The wavelength is the distance between two successive points in the medium that are in phase with each other. The frequency is the number of waves that pass a given point in the medium per unit time. The speed of a transverse wave is determined by the properties of the medium, such as its density and elasticity.

One interesting property of transverse waves is that they can undergo polarization, which is the process of filtering out waves that vibrate in a certain direction. This is commonly used in polarized sunglasses to reduce glare from reflective surfaces.

Therefore, transverse waves are a type of wave where the particles of the medium vibrate perpendicular to the direction of wave propagation. They are characterized by their amplitude, wavelength, frequency, and speed, and can undergo polarization. Transverse waves have important applications in fields such as optics, communication, and seismology.

If the shutter speed is not a fraction (i.e. it is more than a second), it is sometimes preceded by a quote mark or " — for example, 8" is an eight second shutter speed while 8 is a 1/8 second shutter speed. The shutter speed is frequently displayed on cameras with a top-mounted LCD screen.

you replace a 100-watt light bulb with a 25-watt compact fluorescent bulb. over a 10,000 hr life, how much energy, in kilowatt-hours, do you save? if electricity costs $0.15 per kilowatt-hour how much money do you save?

Answers

If you replace a 100-watt  light bulb with a 25-watt compact fluorescent bulb, over a 10,000 hr life, you will save electricity bill of  $112,5

A fluorescent bulb is more energy efficient than an incandescent bulb. It produces the same amount of light with less electricity.

The energy used by the bulbs is often expressed in Kwh or kilowatt-hour.

The formula is:

Kilowatt-hours = power (in kilowatt) x time usage (in hours)

In the given problem:

Time usage = 10,000 hours

Light bulb:

Power = 100 watt = 0.1 kw

kwh = 0.1 x 10,000 = 1,000 kwh

electricity bill = 1000 kwh x $0.15/kwh = $150

fluorescent bulb

Power = 25 watt = 0.025 kw

kwh = 0.025 x 10,000 = 250 kwh

electricity bill = 250 kwh x $0.15/kwh = $37,5

Money save =  $150 - $37,5 = $112,5

Fig. 23-11 how the variation of the electric potential V (meaured in Volt) a a function of the radial direction r (meaured in meter). For which range of r i the magnitude of the electric field the larget?

Answers

As you walk away from the charge, the potential becomes less negative and actually grows, coming closer and closer to zero.

If you are infinitely far away from the charge, the potential for both positive and negative charges is zero. The electric potential (also known as the electric field potential, potential drop, or electrostatic potential) is defined as the amount of work energy required to transport a unit of electric charge in an electric field from a reference point to a specified place. The Volt difference dropped across a fixed resistance of one ohm with a current of one ampere running through it is the unit of potential difference formed between two locations.

A block is released from rest on an inclined

plane and moves 3.4 m during the next 5.5 s.

The acceleration of gravity is 9.8 m/s^2


What is the frictional force acting on the

13 kg mass?

Answer in units of N.

Answers

The frictional force acting on the 13 kg mass is 40.65 N.

What is the acceleration of the block?

The acceleration of the block is calculated by applying the following kinematic equation as shown below.

s = ut + ¹/₂at²

where;

u is the initial velocity of the block = 0t is the time of motion of the blocka is the acceleration of the blocks is the distance travelled by the block

s = 0 + ¹/₂at²

¹/₂at² = s

at² = 2s

a = 2s / t²

a = (2 x 3.4) / (5.5²)

a = 0.225 m/s²

The frictional force acting on the 13 kg mass is calculated as follows;

W sinθ - F = ma

where;

W is the weight of the blockθ  is the angle of inclination of the blockF is the frictional forcem is the mass of the blocka is the acceleration of the block

(13 x 9.8 x sin20) - F = 13 x 0.225

43.57 - F = 2.925

F = 43.57 - 2.925

F = 40.65 N

Find the slope in the x-direction at the point P(0,2,f(0,2)) on thegraph of f when f(x,y)=2(2x+y)e-xy

Answers

-4 is the slope in the x-direction at the point (0,2) on the given graph.

what is Slope of a given curve?

A curve's slope at a given point is the same as the slope of the straight line that is perpendicular to the curve there.

To find the slope along x direction is given by:

slope along x-direction= δ(f(x))/δ(x)

=> δ([tex]2(2x+y)e^-^x^y[/tex])/δ(x)

=> 4[tex]e^-^x^y[/tex] - [tex]2y(2x+y)e^-^x^y[/tex]

we have to find the value of slope at point (0,2)

so the value of x=0 and y=2 in the above equation we get:

=> 4 [tex]e^2^*^0 -2*2(2*0+2)*e^2^*^0[/tex]

=> 4 - 4( 0 +2) *1

=>4-8

=>-4

so the slope along x-axis at point (0,2) is -4.
