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=0.143 kg
Explanation:
From the Newton's second law of motion the force applied to an object is directly proportional to the acceleration produced and the acceleration is in the direction of the force.
F=ma where F is the force, m is the mass of the object and a i the acceleration.
m=F/a
=4.719N/33 m/s²
=0.143 kg
The differences in energy released by earthquakes are too large to express with linear scales.
Ek = (m*V^2) / 2 where m is mass and V is speed, then we can take this equation and manipulate it a little to isolate the speed.
Ek = mv^2 / 2 — multiply both sides by 2
2Ek = mv^2 — divide both sides by m
2Ek / m = V^2 — switch sides
V^2 = 2Ek / m — plug in values
V^2 = 2*30J / 34kg
V^2 = 60J/34kg
V^2 = 1.76 m/s — sqrt of both sides
V = sqrt(1.76)
V = 1.32m/s (roughly)
