Potential energy is gained here as he swings.
b. Shape
c. Brightness
d. Weight
Correct answer choice is :
C) Brightness
Explanation:
A sheet of white paper seen in the bright sunlight reveals a very different quantity of light than the same sheet of paper seen later that night in a softly illuminated room. Yet we regard the paper as having the same paleness in each case. This is an instance of brightness constancy, our capability to see objects as proceeding to have the same brightness even though light may change their direct visual features.
Answer:
The first one.
If the road becomes wet or crowded, you should slow down and increase your following distance.
If the road becomes wet or crowded, you should slow down and increase your following distance. This is important because wet roads reduce tire traction and increase the risk of sliding and losing control. By slowing down and increasing your following distance, you give yourself more time to react and stop if necessary.

The correct answer is
A concave lens diverges light and curves inward.
A picture of a concave lens and the ray diagram produced by it can be seen in attachment. As it can observed, the concave lens (also called diverging lens) is wider at the edges and narrow at the centre (so, it curves inward), and it can also be seen that the lens diverges the incoming light rays.
A concave lens diverges light and curves inward is the statement which
describes its characteristics.
This type of lens is used to treat short-sightedness and has at least one of
its surface curving inward. This helps it to spread out light rays so as to
ensure proper view.
It has a high degree of diffraction and is the reason why option A was
chosen as it's the most appropriate choice.
