Answer:
![F_5 >F_4>F_1 >F_2>F_3](https://tex.z-dn.net/?f=%20F_5%20%3EF_4%3EF_1%20%3EF_2%3EF_3)
Where
represent the force for each of the 5 cases
presented on the figure attached.
Explanation:
For this case the figure attached shows the illustration for the problem
We have an inverse square law with distance for the force, so then the force of gravity between Earth and the spaceship is lower when the spaceship is far away from Earth.
Th formula is given by:
![F = G \frac{m_{Earth} m_{Spaceship}}{r^2}](https://tex.z-dn.net/?f=%20F%20%3D%20G%20%5Cfrac%7Bm_%7BEarth%7D%20m_%7BSpaceship%7D%7D%7Br%5E2%7D)
Where G is a constant ![G = 6.674 x10^{-11} m^2/ (ks s^2)](https://tex.z-dn.net/?f=%20G%20%3D%206.674%20x10%5E%7B-11%7D%20m%5E2%2F%20%28ks%20s%5E2%29)
represent the mass for the earth
represent the mass for the spaceship
represent the radius between the earth and the spaceship
For this reason when the distance between the Earth and the Spaceship increases the Force of gravity needs to decrease since are inversely proportional the force and the radius, and for the other case when the Earth and the spaceship are near then the radius decrease and the Force increase.
Based on this case we can create the following rank:
![F_5 >F_4>F_1 >F_2>F_3](https://tex.z-dn.net/?f=%20F_5%20%3EF_4%3EF_1%20%3EF_2%3EF_3)
Where
represent the force for each of the 5 cases
presented on the figure attached.
Answer:
The value of change in internal energy of the gas = + 1850 J
Explanation:
Work done on the gas (W) = - 1850 J
Negative sign is due to work done on the system.
From the first law we know that Q = Δ U + W ------------- (1)
Where Q = Heat transfer to the gas
Δ U = Change in internal energy of the gas
W = work done on the gas
Since it is adiabatic compression of the gas so heat transfer to the gas is zero.
⇒ Q = 0
So from equation (1)
⇒ Δ U = - W ----------------- (2)
⇒ W = - 1850 J (Given)
⇒ Δ U = - (- 1850)
⇒ Δ U = + 1850 J
This is the value of change in internal energy of the gas.
The non-relativistic formula for low speed v < 0.1c is:
K.E = 0.5mv^2 = 0.5 * 235 * (7)^2 = 5757.5 J
