What do we mean by gravitational time dilation?

Physics
1 answer:
Katena32 [7]3 years ago
8 0

Answer:

The dilation of time is a phenomenon that results from the theory of relativity proposed on 1905 by Einstein.

This theory, states (under the condition of the invariance of the speed of light in vacuum) the measurement on a body is made with reference to the system in which it is being measured and that time passes at different rates in regions of different gravitational potential.  

That is:

<h2>The greater the local distortion of space-time due to gravity, the slower the time passes.  </h2>

mina [271]

Answer:

Electromagnetic radiation is an electric and magnetic disturbance traveling through space at the speed of light (2.998 × 108 m/s). It contains neither mass nor charge but travels in packets of radiant energy called photons, or quanta.

what is the transfer of heat energy by direct contact. A . convection b. radiation c. thermal or heat and d. conduction ​
katrin2010 [14]

Answer:

d. conduction ​

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Any material or object that allow the conduction (transfer) of electric charge or thermal energy is generally referred to as a conductor. Conductors include metal, steel, aluminum, copper, frying pan, pot, spoon etc.

In conclusion, conduction typically involves the transfer of heat energy by direct contact between two or more conductors such as a pot and electric cooker.
