Which pair of properties apply to both sound and electromagnetic waves? a) both waves carry energy and refract. b) both waves are longitudinal and carry energy. c) both waves are transverse and need a medium. d) both waves carry energy and do not need a medium to travel through.

A. Both waves carry energy and refract is the correct answer.

Explanation:

A) Both waves carry energy and refract.

Explanation:

Sound waves are longitudinal waves, and electromagnetic waves are transverse waves. So as they are a different type of wave we discard options B and C.

Also sound waves unlike electromagnetic waves, they do need a medium to propagate, which discards option D.

This leads us to the correct option that is A. Both waves carry energy and refract.

All waves are a perturbation that carries energy. Also, refraction occurs in both types of waves, this because both change direction when moving from one medium to another.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
