Ice floats on water because ice is less dense than water. how is this to fish that live in a lake? . a. it shades the fish from the sun.. b. it keeps the fish warm in the winter.. c. it the fish stay cold in the winter.. d. it blocks oxygen from reaching the water..

option B is true . It keeps the fish warm in the winter.

Explanation:

As the density of ice less than water so it floats on the surface of water. The temperature inside the water is more than the surface so he fishes swim inside the water and becomes warm in winters.

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.
