<h2>
Answers:</h2>
-The first direct detection of gravitational waves came in 2015
-The existence of gravitational waves is predicted by Einstein's general theory of relativity
-Gravitational waves carry energy away from their sources of emission
<h2>
Explanation:</h2>
Gravitational waves were discovered (theoretically) by Albert Einstein in 1916 and "observed" for the first time in direct form in 2015 (although the results were published in 2016).
These gravitational waves are fluctuations or disturbances of space-time produced by a massive accelerated body, modifying the distances and the dimensions of objects in an imperceptible way.
In this context, an excellent example is the system of two neutron stars that orbit high speeds, producing a deformation that propagates like a wave,<u> in the same way as when a stone is thrown into the water</u>. So, in this sense, gravitational waves carry energy away from their sources
.
Therefore, the correct options are D, E and F.
centimeter or millimeter.
Explanation:
The unit of length most suitable for measuring the thickness of a cell phone is centimeter or millimeter.
Length refers to how long a material is.
- There are different units of length.
- Smaller units that are microscopic are used to measure length dimensions that are very small
- For example, nanometre is used to express microscopic length values.
- Centimeters and millimeters are used for small dimensions that we can easily see.
- Longer lengths can take the order of a yard, kilometer, miles e.t.c

Answer:
Help out with the laundry himself.
