I think the correct answer would be the last option. On a cloudless day, most of the visible light that is headed towards the Earth would reach the surface wherein  some is being reflected and some is being absorbed. During this time, there are no hindrances for the light so it directly reaches the surface of the Earth and is absorbed or reflected by the objects it hits.

When an object oscillating in simple harmonic motion is at its maximum displacement from the equilibrium position. What are its
xxMikexx [17]

Answer:

Speed = 0

Restoring force = maximum

Explanation:

Suppose this situation as a spring with a mass attached to it, that oscilates.

The force that the spring does (the restoring force in this case)  is something like

F = K*L

where K is the constant of the spring, and L is the difference between the length of the spring (stretched) and the length of the spring at rest.

Then, when the harmonic oscillator is at its maximum displacement, L takes its maximum value, which means that at this point the restoring force must also have a maximum.

And for the velocity, at this point we have the maximum displacement, this means that, if the mass was moving to the right, after this point the mass stops going to the right, and then returns to the equilibrium position to the left.

Then the velocity has a change of sign, (like an object that reached its maximum height) this means that at that exact moment, the velocity must be zero.

Then:

Speed = 0

Restoring force = maximum

Answer:

Asteroids

Explanation:

Asteroids are the small and large block of rocks that are found to be scattering space. There are numerous asteroids present in the asteroid belt which is located between the planet of Mars and Jupiter. These range from a  few meters to hundreds of kilometers. They move so rapidly, at about 80,000 km/hr and there occurs constant collision with one another. These asteroids sometimes enter into the atmosphere of earth, which can cause a great mass extinction event.

These are believed to be the remnants particles that are present in space right after the formation of the solar system.
