Answer:
Because it is said that the earth rotates and revolves around the sun and moon so it is impossible for the earth not to be spinning.
Explanation:
Pretty sure it is B.
Because inertia is a tendency to do nothing or remain unchanged.
100 cm is 1 meter. So your answer would be 0.362 meters.
The mass of the petcock of the pressure cooker is 0.257 kg.
The total pressure inside the cooker is= atmospheric pressure+Gauge pressure
=100 kPa+101 kPa=201*10^3 Pa
The area of the petcock is= (π/4)d^2=0.785*0.004^2=12.56*10^(-6) m^2
Now the mass of the petcock is calculated as
P=(F/A)=(mg/A)
201*10^3=(m*9.81/(12.56*10^(-6)
m=0.257 kg
Therefore the mass of the petcock is 0.257 kg
