An electromagnetic wave moves through electric and magnetic fields. What is the relationship between the wave and the fields?
O A. The vibrations of the fields are in the same direction but
perpendicular to the motion of the wave.
B. The vibrations of the fields are at 90° angles to the direction of
motion of the wave.
C. The vibrations of the fields and wave motion are all parallel to
each other.
D. The vibrations of the fields and the wave motion are at 180°
angles to each other.

B. The vibrations of the fields are at 90° angles to the direction of

motion of the wave.

Explanation:

Electromagnetic waves are waves that are produced by the vibration of the electric and magnetic fields.

Both fields are oriented perpendicularly to one another. This vibration produces the electromagnetic waves.

These waves are very unique in that they do not require any material medium for propagation.

There is a broad spectrum of electromagnetic waves with gamma rays being the most energetic and radio waves being the least energetic.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

the right answer is 0.3 meters per second
