Answer:
false
Explanation:
Because the sun has ultraviolet rays
In the motion of the medium particles in a longitudinal wave, the medium vibrates parallel to the direction of the wave.
<h3>What is a longitudinal wave?</h3>
A longitudinal wave is a wave that is transversing along the length. When the displacement of medium and travel of wave is the same in that condition wave is known as the longitudinal wave.
It requires some medium to travel. A mechanical and sound wave is an example of a longitudinal wave.
Hence in the motion of the medium particles in a longitudinal wave, the medium vibrates parallel to the direction of the wave.

Not possible. The air is actually able to travel sound throughout itself without any difficulties. I believe, air actually brings sound closer to the people farther away ; It really helps to stretch sound.
Based on the weights of the crate on the different planets, the mass of the given planets compared to the earth are as follows:
- Mercury - lower mass than Earth
- Venus - lower mass than Earth
- Mars - lower mass than Earth
- Jupiter - higher mass than Earth
- Saturn - higher mass than Earth
- Uranus - higher mass than Earth
- Neptune - higher mass than Earth
<h3>What does the weight of an object depend on?</h3>
The weight of an object depends on the mass of the object as well as a constant known as acceleration due to gravity, g.
For an object of constant mass, its weight depends only on the acceleration due to gravity on the object.
The higher the mass of an object, the greater will be its value of acceleration due to gravity.
Hence, for planets in which the weight of the object is less than on earth, the planets will have a lower mass than earth. On the other hand, for planets in which the weight of the object is more than on earth, the planets will have a higher mass than earth.
