Una máquina industrial es capaz de transformar 1.440,6J de energía potencial en cinética, y ésta a su vez convertirla en calor, sin que haya pérdidas de energía en dicho proceso. Si con el calor generado se quiere calentar un pequeño recipiente que contiene 25,6 ml de agua pura que está a 50ºC, ¿qué temperatura alcanzará el agua?

the answer would be c

i believe the answer is a hope it and is correct

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.
