Answer:
Suppose the micrometeoroid weighed 1 g = .001 kg
Suppose also the spacecraft were moving at 18,000 mph (1.5 hrs per rev)
Usually, the smaller particle would be moving but for simplicity suppose that it were stationary wrt the ground
v = 18000 miles / hr * 1500 m/mile / 3600 sec/hr = 7500 m/s
KE = 1/2 * .001 kg * (7500 m)^2 = 28,125 Joules
One can see that 28000 Joules could be damaging amount of energy

Answer:
d. 10000N
Explanation:
When a force (
) is exerted on the smaller area piston (
), the pressure that originates therein is transmitted to the larger area piston(
). According to Pascal's principle the pressure on the smallest piston (
) will be equal to the pressure on the largest piston (
):
