Answer:
1471.5 Newton
10
Explanation:
Small piston area = A₁ = 2 m²
Large piston area A₂ = 20 m
m = Mass of car = 1500 kg
g = Acceleration due to gravity = 9.81 m/s²
Force
F = mg = 1500×9.81 = 14715 N
Force applied by car is 14715 N
a) Pascal's law
Force required is 1471.5 Newton
b) Mechanical advantage
Mechanical advantage is 10
Answer:
b and e
Explanation:
r x F is the formula for torque.
The "turning effect" or torque happens when concentric forces rotate an object along said center.
a) False because T = Fr = Ia (a = angular acceleration)
b) True
c) False. L = Iw (w = angular velocity), which does not equal Ia
d) False. It is torque, not the product of torque and something else
e) True.
Anything that is possibly solid or can be contained in a solid
Mass is the amount of matter that is contained in a certain object.
Like
20 kg
10 g
100 lb
Added potential energy = (mass) x (gravity) x (height)
or
Added potential energy = (weight) x (added height)
If you need to lift a 15N box 3m straight up, you have to increase its potential energy by (15 N) x (3 m) = 45 Joules .
Where is that added potential energy supposed to come from ? You could use an electric winch, a steam engine, a gasoline-powered motor, thousands of hamsters running on little treadmills that are are connected to the main pulley somehow, or your own arm muscles. But howEVER you do it, you have to provide <em>45 Joules</em> of WORK in order to increase the potential energy of the box by just that much.
