Which statement describes a characteristiccommon to all electromagnetic waves and
mechanical waves?
(1) Both types of waves travel at the same speed.
(2) Both types of waves require a material medium
for propagation.
(3) Both types of waves propagate in a vacuum.
(4) Both types of waves transfer energy.

Answers

Answer 1

Answer: "(4) Both types of waves transfer energy." is the best option from the list regarding the characteristics common to all electromagnetic waves and mechanical waves

Answer 2

Answer:

Answer: The correct answer is (4).

Explanation:

Electromagnetic wave is the transverse wave. It is produced by the moving charged particle. It travels at the speed of the light. It does not require a medium to travel. It can travel through the vacuum.

In mechanical wave, there is an oscillation of matter. It requires a medium to travel.It cannot travel through vacuum. The three types of mechanical waves are longitudinal wave, transverse wave and surface wave.

The common characteristics to all electromagnetic waves and mechanical waves are both can move through matter and both can occur as a result of a disturbance. This disturbance is a result of wave transfer energy.

Therefore, the common characteristic to all electromagnetic and mechanical waves is both types of waves transfer energy.

Tech A says that a battery stores electrical energy in chemical form. Tech B says that a battery creates direct current. Who is correct?

Answers

Answer:

Battery stores the electrical energy in the chemical form. When we connect it's positive and negative terminals and provide the path for the flow of electrons then it converts that chemical energy into the electrical energy and hence the direct current is created. So both of the technicians are right.

If you know the distance an object has traveled in a certain amount of time you can determine

Answers

With that information, you can determine the object's speed.
Just divide the distance covered by the time to cover the distance.

If you also know the direction the object moved, then you can
determine its velocity. If you don't, then you can't.

You can determine the velocity it is moving at.
