Allison wants to calculate the speed of a sound wave. which formula should she use? distance traveled / amplitude number of wavelengths / amplitude number of wavelengths / time distance traveled / time

Option 4th is correct

distance traveled / time

Explanation:

Allison wants to calculate the speed of a sound wave.

The speed of the sound wave is the distance traveled divided by the time.

Where, v = speed of sound

d = distance

t= time

Therefore, The formula should she use is, distance traveled / time

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.
