Explanation :
The points regarding the gravitational waves are as follows :
(1) Gravitational waves are predicted to travel through space at the speed of light. So, the speed of gravitational waves is also equals .
(2) The first direct detection of gravitational waves came in 2015. It is detected using a advanced LIGO detectors.
(3) The existence of gravitational waves is predicted by Einstein's general theory of relativity.
Hence, the correct options are (B), (D) and (E).
Answer:
Mass, m = 4 kg
Explanation:
<u>Given the following data;</u>
Energy = 3.6 * 10^17 Joules
We know that the speed of light is equal to 3 * 10⁸ m/s.
To find the mass of the substance;
The theory of special relativity by Albert Einstein gave birth to one of the most famous equation in science.
The equation illustrates, energy equals mass multiplied by the square of the speed of light.
Mathematically, the theory of special relativity is given by the formula;
Where;
- E is the energy possessed by a substance.
- m is the mass.
- c is the speed of light.
Substituting into the formula, we have;
Mass, m = 4 kg
