Answer:
option E.
Explanation:
When the ball is at the highest point the velocity of the ball is zero.
At the height point the kinetic energy is zero and potential energy is maximum.
At maximum point momentum cannot be maximum because velocity is zero.
Acceleration on the ball is equal to acceleration due to gravity on the ball.
Hence, the correct answer is option E.
Exothermic is the right kind of reaction.
Galaxy-a collection of dust, gas, AND STARS. But I'm pretty positive this should be the answer.

<u>Answer:</u>
<em>Sand in a beach is warmer than the water of the sea.
</em>
<u>Explanation:</u>
<em>Water absorbs less heat from the sun</em> when compared with sand. Sand is darker and also is less reflective. Because of its darker nature, absorption of heat from the sun will be more. Due to its less reflective nature the sand wouldn’t be able to<em> reflect off the sunlight.
</em>
But water is highly reflective and can reflect off a <em>major portion of the sunlight falling on the sea</em>. The sea is also deep and thus the heat spreads through a large volume unlike in the <em>case of sand.</em> Water also has the nature of constant movement unlike sand which is stable.
<em>This factor also heats up sand more than water.
