What type of issue does the effects manufacturer need to overcome in order to be able to mass produce this
echo device?
Amanufacturer of echo effects for music recording
studios has built a prototype of an echo device that
sounds exactly like a beloved echo machine from the
1970s. Even though its computer chips are cheap, they
are hard to find because the compounds originally used
to make the chips are no longer being manufactured.
A. availability
B. cost effectiveness
C. safety
D. time effectiveness

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.
