<u>Astronauts are not weightless during either launch or return to Earth.</u>
<u></u>
<h3>
Brief explanation</h3>
Astronauts become weightless when they stop accelerating. Basically that means when the engines cut out and they begin to coast in orbit. They will remain “weightless” for as long as they are in orbit. To get out of orbit, they have to decelerate (i.e. Accelerate in the opposite direction) and so they begin to feel a force that feels very much like gravity as they are falling back to Earth.
One of the cool things is that you can't tell the difference between gravity and acceleration. They're the same thing as far as your body is concerned. Einstein used a variety of somewhat related thought experiments while he has working out the details of the special theory of relativity.
Hence, with this explanation , we can conclude that astronauts are not weightless during either launch or return to Earth.

The mass of the soil sample is 82g.
- The container has a mass of 15g.
- Let the mass of the soil be "x" g.
- The mass of the container and soil combined is 97g.
- container mass + soil mass = total mass
- 15g + x = 97g
- x = 97g-15g
- x = 82g
- The amount of matter that makes up a physical body is known as its mass. It serves as a gauge for the body's inertia.
- The amount of matter that makes up any item or body is the best way to define mass. Everything we see around us is made of mass.
- In physics, mass is the most fundamental characteristic of matter and one of the fundamental quantities. The amount of matter in a body is referred to as its mass. The kilogram is the kilogram, which is the SI unit of mass (kg).

Answer:
The balance between incoming energy from the sun and outgoing energy from Earth ultimately drives our climate. This energy balance is governed by the first law of thermodynamics, also known as the law of conservation of energy.
