A hollow, conducting, discharge sphere of mass floats in a dielectric liquid of constant K, keeping 3/4 of its volume out of the liquid. At what potential must the sphere be charged to float half its volume

the answer is a. at the equator

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

that would be because of both gravity and friction. so     c

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.
