Answer: The correct answer is "electromagnetic wave".

Explanation:

Electromagnetic waves: These waves are produced by vibration of the charged particles. But the mechanical waves are caused by wave amplitude.

Electromagnetic wave does not need a medium while the mechanical wave needs a medium to travel.

The electromagnetic wave travels with the speed of the light. The example of electromagnetic wave is light.

Mechanical waves are of two types: Longitudinal wave and Transverse.

Sound wave is a longitudinal wave. It consists of compression and rarefaction.

Therefore, Light travels as an electromagnetic wave.

The correct answer is electromagnetic. Lights travel as an electromagnetic wave. In fact, light is an electromagnetic radiation which has a center of the electromagnetic spectrum. Light is visible to the naked eye, and is responsible for an organism's sense of sight.

Leto [7]

<span>The question is asking us what is BEST to say about a runner who is running at a constant velocity? A constant velocity (=speed) means that they are not getting faster or slower - they are running exactly as fast all the time. This meanst that their speed does not change, so their change of speed is equal to 0. A change of speed is called acceleration so their C. Their acceleration is zero. - C is the correct answer. </span>

A ship is travelling due east at 30 km/hr and a boy runs across the deck

dsp73

Answer:

Vr = 20 [km/h]

Explanation:

In order to solve this problem, we have to add the relative velocities. We must remember that velocity is a vector, therefore it has magnitude and direction. We will take the sea as the reference measurement level.

Let's take the direction of the ship as positive. Therefore the boy moves in the opposite direction (Negative) to the reference level (the sea).

$V_{r}=30-10\\V_{r}=20 [km/h]$
