Una esfera de latón macizo (B = 35 000 MPa) cuyo volumen es 0.8 m3 se deja caer en el océano hasta una profundidad en la cual la presión hidrostática es 20 Mpa mayor que en la superficie. ¿Qué cambio se registrará en el volumen de la esfera?

i think the answer is a, hope this : )

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.
