Answer:
a) The total force is 4659.8 N
b) The gauge pressure is 50764 Pa
Explanation:
Given:
Pressure inside = 0
Patm = pressure outside = 1.013x10⁵Pa
Pressure difference = ΔP = 1.013x10⁵ - 0 = 1.013x10⁵Pa
a) The area is equal:

The force is:

b) The gauge pressure at the bottom is equal:

Where:
ρ = density = 1000 kg/m³
h = 17 ft = 5.18 m
Replacing:

Answer:
it is the 3rd answer choice
Answer:
This is not a question, but a statement. The concept that the work done is equal to the input work on a simple machine is called ideal machine. An ideal machine has 100% efficiency which means that there is no loss. All the amount of input work is equal to the useful output of the machine.
