Answer:
At point A, the cart has high potential energy. At point b, the cart is pulled down by gravity. At point c, the cart gains its highest kinetic energy. At point d, the cart returns back to the same state but with lower potential energy.
In an exothermic reaction, there is a transfer of energy to the surroundings in the form of heat energy. The surroundings of the reaction will experience an increase in temperature. Many types of chemical reactions are exothermic, including combustion reactions, respiration & neutralization reactions of bases & acids.

whats the Question? (i play softball and its amazing btw lol)(ugh staying at home is getting to me)
Explanation:
Answer: D. Diffract
Explanation:
Diffraction is a phenomenon that is based on the deviation of the waves (light waves in this case) when encountering an obstacle.
In addition, it is important to note this phenomenom occurs in all types of waves (ncluding electromagnetic waves).
So, in a general way:
Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit . When this occurs, the wave bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle.
Hence, the correct option is D:
<h3>In order to demonstrate the interference of light waves, the light source emits rays of light, which <u>diffract</u> towards the double slit.</h3>
