Answer:
Weight = 105 Newton
Explanation:
Given the following data;
Mass = 70kg
Force of gravity = 1.5N/kg
To find the weight;
Weight = mass * force of gravity
Substituting into the equation, we have;
Weight = 70 * 1.5
Weight = 105 Newton
Therefore, the weight of the astronaut when they are on the Moon is 105 Newton.
Answer:
A - ¼ of the force
Explanation:
According to Pascal’s principle, there's an equation that relates the force to area ratios in hydraulic systems, provided that the pistons will be at the same vertical height and that the friction in the given hydraulic system is negligible. This formula is;
F1/A1 = F2/A2
Thus;
F1/F2 = A1/A2
Where F is the applied force and A is area of pad.
Now, we are told that the size of the pad is doubled. Thus;
If the initial radius is r, then the new radius is 2r
Thus;
F1/F2 = (πr²)/(π(2r)²)
F1/F2 = r²/4r²
F1/F2 = ¼
F1 = ¼F2
Thus, the answer is ¼ of the force
