Without light, we would still have food to eat and oxygen to breathe.
True
False

false.

Explanation: without light, plants will not grow. plants play a major roll in the food chain. animals would eventually run out of plants to eat then maybe turn to cannibalism. as for oxygen, trees take in carbon dioxide and convert it to oxygen. without light, the trees will die. plants, trees and other greens use light to convert to food (photosynthesis.)

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
