Base in your questions that ask what cause the bright lines seen in the emission spectrum and i think the best answer to that is the H2 gas is used when protons was heated so the electron absorb all the photons and get exited and resulted by given of a light.
Geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
Explanation:
The correct statement is that geothermal power plants use the renewable resource of heat from within the Earth to generate electricity.
Geothermal energy is heat energy from within the earth.
- Geothermal energy is not available everywhere on the earth. It is restricted to certain geologic terrains.

Answer:
63.57 kg
Explanation:
weight = 140 lbs
Let the mass is m.
1 lbs = 4.45 N
The weight of an object is defined as the force with which our earth attracts the body towards its centre.
Weight is the product of mass of the body and the acceleration due to gravity of that planet.
W = m x g
On earth surface g = 9.8 m/s^2
Now convert lbs in newton
So, 140 lbs = 140 x 4.45 = 623 N
So, m x 9.8 = 623
m = 63.57 kg
Thus, the mass is 63.57 kg.
