What happens when a sound wave encounters an obstacle in its path? A)A sound wave’s wavelength allows it to pass through objects.
B) Sound waves bend around the corners of obstacles.
C) Sound waves can easily pass through any object.
D) A sound wave’s amplitude allows it to move around objects.

I think it's B maybe

Explanation:

i think the answer is a, hope this : )

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.
