Which statement describes a difference between electromagnetic and mechanical waves? A. Mechanical waves do not transfer energy,
Natasha_Volkova [10]
The answer is D.

Mechanical waves need a medium to travel, for example, sound is a mechanical wave. You are able to hear other people because the sound wave is travelling trough a fluid -air-. If you were to be in space -vacuum- you would not be able to hear anything. 

The most well known example of an electromagnetic wave is light. As you may have noticed, we're able to get the light from the Sun to Earth; clearly light -electromagnetic wave- is able to travel in vacuum/space (i.e., without a medium).

A dog running at 10 m/s is 30m behind a rabbit moving at 5 m/s. when will the dog catch up with the rabbit assuming both their v
dedylja [7]

The will dog catch up with the rabbit in 6 minutes assuming both their velocities remain constant during the chase.

<h3>What time will the dog catch the rabbit?</h3>

The time that the dog will catch up with the rabbit is given as follows:

Let the distance covered by the rabbit be x.

Distance covered by dog = x + 30

  • Time taken = distance/speed

The time taken will be the same T

  1. Time taken by dog, T = (x + 30)/10
  2. Time taken by rabbit, T = x/5

Equating both times.

(x + 30)/10 = x/5

x = 30 m

Solving for T in equation (ii);

T = 30/5 = 6 minutes

In conclusion, time is obtained as a ratio of distance and speed.
