Answer:

C) oxygen reacting with sugar (usatestprep)

Explanation:

Oxygen reacting with sugar during the process of respiration produces water, carbon dioxide, and energy.

Oxygen reacting with sugar is a process by which water, carbon dioxide, and energy are formed, therefore the correct answer is option C.

The energy emitted by the Sun as a form of thermal electromagnetic radiation is known as solar energy. This solar energy is produced by nuclear fusion in the center of the Sun. Solar energy is a form of renewable source of energy.

Thus, Oxygen reacting with sugar is a process by which water, carbon dioxide, and energy are formed, it is a type of exothermic reaction in which excess energy is produced on the product side, therefore the correct answer is option C.

The correct answer is A

Pretty much all the answer is saying is that if you make a dam it limits water supply which is true because it blocks water from flowing smoothly.

Answer: The correct answer is [tex]a=\omega ^{2}r[/tex].

Explanation:

In the circular motion, the speed of the body is uniform but the velocity of the body changes as the direction of the body changes in the circular motion. In the circular motion, there is only centripetal acceleration.

The acceleration of a body revolving in a circle is as follows;

[tex]a=\omega ^{2}r[/tex]

Here, [tex]\omega[/tex] is the angular velocity and r is the radius.

The direction of the centripetal acceleration is directed towards the center of the circle.

Therefore,  the acceleration of a body revolving in a circle at uniform speed is [tex]a=\omega ^{2}r[/tex].
