Suppose your efforts work, and the car begins to move forward out of the mud. As it does so, the force of the car on the rope is

equal to the force of the rope on the car.

Explanation:

When dealing with ropes the force that it exerts and the force being exerted on it is always equal as long as the rope doesn't snap/break. Therefore, the force of the car on the rope is equal to the force of the rope on the car. The fact that the car is moving due to your efforts simply means that you are exerting more force than all the forces that are pushing in the opposite direction, mainly gravity and friction. Since the force you are exerting is greater it allows you to move the car, but as long as the rope remains intact then the force on the rope is equal on both sides.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
