The correct answer is:
Absorber
An absorber is a material that takes in a wave when the wave hits it.
Answer:
The answer is they utilized light in a few spots to enlighten the subjects and to demonstrate their volume as masses.
Explanation:
That is the reason every one of the particles that move at the speed of light (e.g. photons) have zero rest mass. As a molecule with mass methodologies the speed of light, its vitality increments and winds up unbounded at the speed of light, which is the motivation behind why it can never be quickened to achieve that speed. However, you can state that the photon has relativistic mass on the off chance that you truly need to. In current wording, the mass of a protest is its invariant mass, which is zero for a photon.
10 trillion km is the corrct asnwer
Answer:
h=2.86m
Explanation:
In order to give a quick response to this exercise we will use the equations of conservation of kinetic and potential energy, the equation is given by,
There is no kinetic energy in the initial state, nor potential energy in the end,
In the final kinetic energy, the energy contributed by the Inertia must be considered, as well,
The inertia of the bodies is given by the equation,
On the other hand the angular velocity is given by
Replacing these values in the equation,
Solving for h,
I believe the correct answer from the choices listed above is the second option. In a nuclear power plant, nuclear energy is first changed to thermal energy. Heat energy is first given off in this process. Hope this answers the question. Have a nice day.
