Explanation:
A force of 500N acts on the area of 2.5m2; calculate the pressure
exerted,
(Ans: 200 Pa]
b. Calculate the force applied when 400 Pa of pressure is exerted by a box
of surface area 2m2.
(Ans: 800 N]
The weight of a stone is 1400N. If it exerts a pressure of 700 Pa, calculate
the area.
(Ans: 2m]
d. A force of 2000 N acts on 5m² surface area. Calculate the pressure
exerted.
(Ans: 400 Pa]
c.

Orbits are the result of a perfect balance between the forward motion of a body in space, such as a planet or moon, and the pull of gravity on it from another body in space, such as a large planet or star. An object with a lot of mass goes forward and wants to keep going forward; however, the gravity of another body in space pulls it in. There is a continuous tug-of-war between the one object wanting to go forward and away and the other wanting to pull it in.
Answer:I think its the first one

Answer:c>a>b
Explanation:
Given
All the engine extracts same amount of heat(Q) from High-temperature reservoir
For a) 400 and 500 K
For b)500 K and 600K
For c) 400 K and 600 K
So c will give the highest amount of work
c>a>b
