Which type of wave cannot travel through a vacuum? visible light waves X-ray waves gamma ray waves sound waves
2 answers:
The correct answer to the question is- Sound waves i.e the sound waves can not move through vacuum.
EXPLANATION:
Sound wave is a mechanical longitudinal wave which requires a medium for its propagation. The medium may be solid,liquid or gas. It can not travel in space or vacuum.
As per Clark Maxwell's electromagnetic theory, the electromagnetic radiations are the waves which contain time varying electric and magnetic fields which are perpendicular to each other as well as perpendicular to the direction of propagation. Any electromagnetic wave can travel in space with the velocity of light i.e .
As per the question, we have X-ray, gamma ray,visible light and sound wave.
Except sound, all the waves i.e visible light, gamma ray and X-ray are electromagnetic in nature. So, these waves can travel in space.
Hence, the correct answer of this question is sound wave which can not travel in space or vacuum.

Answer: A- It would increase
Explanation:
According to the law of universal gravitation:
Where:
is the module of the attraction force exerted between both objects
is the universal gravitation constant.
and
are the masses of both objects
is the distance between both objects
As we can see, the gravity force is directly proportional to the mass of the bodies or objects and inversely proportional to the square of the distance that separates them.
In other words:
<h2>If we decrease the distance between both objects, the gravitational force between them will increase. </h2>
