Dr. evil captures justin bieber ( water is pouring into a large cylindrical tube that is 2 m tall. the tube is open on one end and has water in the other end (closed). the water pours in at a rate of 1 cm in height every minute. when the water reaches a height that will cause the tube to play 220 hz (a, three octaves above middle c), bieber will drop into a shark-infested pool (sharks with freaking lasers). no demands this time, he just wants to do it for fun. how long does bieber have to live?

no sign of dia of fuel cell

cant without the picture! ?

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.
