It all comes to the doppler effect, the red shift means that the galaxy is moving away from us. The redshift is a result from the doppler effect, so as the galaxy moves away the wavelength expands, increasing the wavelength which responds to the red light.
Answer:
from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection, and radiation. Sometimes more than one may occur at the same time.
Explanation:
Answer:
You could conclude the 2nd fact
Explanation:
The volume of a gas will increase by ten times if the temperature is increased by ten times.
<h3>Relationship between the volume of a gas and temperature</h3>
The relationship between the volume of a gas and its temperature is explained in Charles' law of gases which states that:
- The volume of a fixed mass of gas is directly proportional to its temperature provided the pressure of the gas is kept constant.
This means that if the temperature of a gas is increased by any given factor, the volume increases by the same factor proportionally.
Therefore, if the volume of a gas will increase by ten times if the temperature is increased by ten times.

Gravitational force equals GMm/r^2, where G is constant, M and m are the masses, and r is distance.
For I, if both masses double, the formula becomes G2M2m/r^2, or 4GMm/r^2. Therefore, the gravitational force will quadruple or 4x.
For II, if the distance between the object doubles, the formula becomes GMm/(2r)^2 or GMm/4r^2. In this case, the gravitational force is 1/4x the initial force.
