Answer:
The work done is calculated as
Solution:
As per the question:
Mass of the spaceship, m = 3500 kg
Height of the orbit, h = 220 km
Mass of the earth,
Height of the higher orbit, h' = 360 km
Radius of the orbit,
Now,
The work done is given by the change in the gravitational potential energy:
Gravitational Potential Energy, U =
Now, for the lower orbit:
For upper orbit:
Change in the gravitational Potential energy:
Therefore, the work done:
Answer:
124 kPa
Explanation:
The highest pressure in the water is in the bottom of the cylinder. The reason is because all the weight of the water and the gasoline puts some pressure plus the atmospheric air. So, the absolute pressure would be the one exerted by the atmosphere, the gasoline and the water and is calculated as follows:
≈124 kPa
