Answer:

Explanation:
The acceleration due to gravity on earth is
regardless of the mass of the object. This means, in the absence of air resistance, both a 3000 kg object and a 300 kg will accelerate at the same rate of
towards earth.
The reason the acceleration due to gravity is the same for all masses is that by grace of nature, the inertial mass
of the object from
equals the gravitational mass
from
, resulting


which is the acceleration that only depends on the mass of earth and its radius, and not on the mass of the object.
A transverse wave transfers energy perpendicular to the direction of wave motion. a longitudinal wave transfers energy parallel to the direction of the wave
We know that the centripetal acceleration is zero, since the summation of forces is the mass times the acceleration in the x- component.
Answer:
A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work on it.
