Their is belt of asteroids between mars and jupiter. this belt circles the "inside" of our solar system and is called the asteroid belt. this belt has a mean radius from the sun of 2.6 au's. how long does it take for 1 asteroid to in the belt to travel around the sun once?

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.

technology is the application of the knowledge gained by science.
