The astronaut's mass doesn't change. It's the same wherever he goes,
because it doesn't depend on what else is around him.
His weight depends on what else is near him, so it changes, depending
on where he is.
Weight = (mass) x (gravity)
On Earth, Weight = (145 kg) x (9.81 m/s²) = 1,422.5 newtons.
(about 320 pounds)
On the moon, Weight = (145 kg) x (1.62 m/s²) = 234.9 newtons.
(about 53 pounds)
Electromagnetic wave bc I studied that early in the year
The energy of a wave is directly proportional to the square of the amplitude of the wave.
<h3>What is the relationship between energy and amplitude?</h3>
There is direct relationship between energy of the wave and the amplitude of the wave. The energy transported by a wave is directly proportional to the square of the amplitude of the wave. This means if energy is increase the amplitude of wave becomes double and vice versa.
Energy = (amplitude)2
So we can conclude that the energy of a wave is directly proportional to the square of the amplitude of the wave.

<span>Pollination is the process by which pollen is transferred to the female part of a plant. The stigma is the central part of the flower, that is supported by a style and is part of the female reproductive organ within plants. Its structure is optimised to promote pollination by having hairs, sticky surfaces and three-dimensional sculptures that capture and trap pollen.</span>
