When a spacecraft travels away from Earth, the gravitational force acting on it
2 answers:
Gravitational force on aircraft at some distance from the Earth is given as
here we know that
= mass of Earth
= mass of aircraft
r = distance between center of earth and aircraft
now as the aircraft is flying away from the surface of Earth so here the distance between them is increasing with the motion of aircraft
So as it moves away the force between them will decrease
So here we can say that
When a spacecraft travels away from Earth, the gravitational force acting on it
<u>decreases</u>

State 1:

We know as well that
To find the mass we apply the ideal gas formula, which is given by
Re-arrange for m,
Because of the pressure, temperature and volume ratio of state 1 and 2, we have to
Replacing,
For conservative energy we have, (Cv = 0.718)
The diameter of the sphere is 2cm.
<h3>How to calculate the diameter?</h3>From the diagram, the first sphere on the ruler is at 4cn and the last sphere is at 12cm.
Therefore, the length will be:
= 12 - 4.
= 8cm
The diameter of one sphere will be:
= Length / 4
= 8/4
= 2
Therefore, the diameter of the sphere is 2cm.
Note that the second question wasn't found online.
