Answer:
Explanation:
The formula for kinetic energy Ke=1/2mv^2 where Ke is kinetic energy, m=mass, and v= velocity.
If the kinetic energy is increased that means that there must be an increase in mass or velocity. However, since the velocity is squared that means that velocity affects the kinetic energy of the object more than the mass does.
<u>Conductivity</u> is the property of matter in which a substance can transfer heat or electricity.

- Fermionic Condensate ( It discovered in 2003 )
Doppler Shift lets you see a star A. Move back and forth
<h3>What is Doppler Shift?</h3>
This refers to the frequency change of a wave in relation to an observer as it moves back and forth.
Hence, we can see that the thing which astronomers can learn from the Radial Velocity Method is D. Period of orbit and minimum mass of a planet as it measures the wavelengths of absorption lines in its spectrum.

Answer:
it is the Hubble law
Explanation:
Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from the Earth at speeds proportional to their distance. In other words, the farther they are the faster they are moving away from Earth.
