Two flies land on a spinning record. one fly, a, lands at the edge of the record at distance, t. the second ty, b, lands on a spot that is at r. what is the relative speed of by b comparedvo ily a a fly b moves at the same speed as fly a. fly b moves at a speed that is ⅓ the speed of fly a. c. fly b moves at a speed that is ¼ the speed of fly a. d. fly b moves at a speed that is twice the speed of fly a. e. fly b moves at a speed that is four times the speed of fly a. ridr) a rider finds herself pressed with her bac

you would expect a sound wave to speed up. - b)

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.
