If the mass of object increases, the weight will stay the same. The weight is a factor which is dependent on gravity, while mass is a constant.
Explanation:
Red-shift
Emission spectra
Light from a star does not contain all the wavelengths of the electromagnetic spectrum. Elements in the star absorb some of the emitted wavelengths, so dark lines are present when the spectrum is analysed. Different elements produce different patterns of dark lines. The diagram shows part of the emission spectrum of light from the Sun.
A gradient colour spectrum of the sun.
Spectra from distant galaxies
Astronomers can observe light from distant galaxies. When they do this, they see it is different to the light from the Sun. The dark lines in the spectra from distant galaxies show an increase in wavelength. The lines are moved or shifted towards the red end of the spectrum. This effect is called red-shift. The diagram shows part of the emission spectrum of light from a distant galaxy.

Red-shift and speed
Astronomers see red-shift in virtually all galaxies. It is a result of the space between the Earth and the galaxies expanding. This expansion stretches out the light waves during their journey to us, shifting them towards the red end of the spectrum. The more red-shifted the light from a galaxy is, the faster the galaxy is moving away from Earth
Answer: It should be Geothermal.
The avantages of geothermal energy are;
1. It is a Renewable and reliable source of energy.
2. It is a clean source of energy and it is sustainable.
3. It has little or no cost of maintenance and operations.
Disadvantages are;
1. It can cause environmental pollution. High concentration of of geothermal can lead green houses gases affecting the atmosphere.
2. It can lead to earthquakes.
3. The geothermal powerplants or cooling system are expensive to maintain and purchase.
Explanation:
Geothermal energy is the heat energy that is gotten from the sun surface of the Earth. It is found in the rock and fluid in the Earth crust.
