Which of the following accurately describe some aspect of gravitational waves? select all that apply. (a) gravitational waves come from funnel-shaped regions of the universe(b) gravitational waves are predicted to travel through space at the speed of light(c) the existence of gravitational waves is predicted by newton's universal law of gravitation(d) the first direct detection of gravitational waves came in 2015(e) the existence of gravitational waves is predicted by einstein's general theory of relativity(f) gravitational waves carry energy away from their sources of emission(g) gravitational waves are an extremely low-energy form of light

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).

god i hope this !

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
