Answer:
Explanation:
Length of bar = L
mass of bar = M
mass of each ball = m
Moment of inertia of the bar about its centre perpendicular to its plane is
Moment of inertia of the two small balls about the centre of the bar perpendicular to its plane is
Total moment of inertia of the system about the centre of the bar perpendicular to its plane is
I = I1 + I2
Answer:
Explanation:
Given
Mass of airplane =21500 kg
Force due to jet engines=35100 N
Force from wind is 14900 N at angle of 75 south of west
Resolving forces
Therefore acceleration in x direction
Direction of acceleration
Answer:
Nuclear fusion would not occur in stars of any mass.
Explanation:
Stars are made of exploding balls of hydrogen and helium. Without the right amount of hydrogen, there would be no nuclear fussion.
Answer:
They arn't usually guesses, but they are well made theorys or explanations. Its a well-substantiated explanation of facts that have been confirmed in expirements.
