Answer:

Explanation:

Renewable energy such as solar energy, wind energy, geothermal energy and hydropower are inexhaustible and obtained from natural sources. This energy can be replenished. Whereas, the non-renewable energy sources such as coal and petroleum products are exhaustible energy. They cannot be replenished. It takes millions of years to form non-renewable energy. The non-renewable energy cause pollution but renewable energy is environment-friendly without being depleted. Therefore, renewable sources of energy better than non-renewable sources.

If a star's radial velocity is -50 km/s, the frequency of its light would appear to be ______ (higher or lower) than its true fr
Phoenix [80]

Answer: If a star's radial velocity is -50 km/s, the frequency of its light would appear to be higher than its true frequency. We usually say that the star's wavelength is blue shifted.

Explanation:

Radial velocity is defined as the velocity of how an object is seen by the axis of a circle.

Then, if the radial velocity is -50km/s, this means that the radius is decreasing, and then that the star is coming towards the viewer.

as the star is coming towards the viewer, we will see a shorter wavelength, which implies that the frequency would appear to be bigger as it really is.

and this is called a blue shift, because the blue light is the visible light with the biggest frequency, while the red light is the visible light with the smallest frequency, then we have:

If a star's radial velocity is -50 km/s, the frequency of its light would appear to be higher than its true frequency. We usually say that the star's wavelength is blue shifted.
