Julie is comparing electromagnetic waves and sound waves. Which of the following words would best complete her chart below? (2 points)

Electromagnetic

Are transverse

Can travel

Fastest without a medium

Group of answer choices

without frequency

through any substance

on a curved path

in a vacuum

in a vacuum

Explanation:

In physics, a transverse wave is a moving wave whose oscillations are perpendicular to the direction of the wave or path of propagation. In a transverse wave, the particles are displaced perpendicular to the direction the wave travels. Electromagnetic waves are transverse waves. They require no material medium for propagation and travel fastest in a vacuum.

Sound waves are longitudinal waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. Sound waves do not travel through vacuum because they require a material medium (air) for propagation. A vacuum has no air hence sound waves do not travel through a vacuum.

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
