Answer:
- the first direct detection of gravitational waves came in 2015
- gravitational waves are predicted to travel through space at the speed of light
- the existence of gravitational waves is predicted by Einstein's general theory of relativity
Explanation:
The gravitational waves are waves that are produced by the objects, and depending on the mass of the object they can be stronger or weaker in their influence.
These waves have been in the minds of the scientists for more than a century now, with Einstein predicting them in his theory of relativity. The only problem with these waves was that there was no proof of them. The proof finally came in 2015 when these waves were detected from the first time, with two black holes to be thanked for that as they were the source of them.
These waves are predicted to be able to travel with the speed of light through space when they have small amplitudes.
Answer:
For the ones that say use calculator try it. Just pop it in and you get your answer :D
Explanation:
rounding
a. 6.54 = 6.5
if the number is 5 or above round up and drop the numbers to the right of it
if its 4 or under drop the numbers to the right of it
in this case your tenth place is 5 so you drop the four.
follow this formula for the rest
