Answer:
Force of friction is 10 N.
Explanation:
Given:
Mass of the table is,
Force acting towards right,
Net acceleration of the table,
Let the force of friction acting on the table to the left be N.
Therefore, net force acting on the table is given as,
Now, as per Newton's second law of motion,
Equating the above two equations, we get
Therefore, the magnitude of the force of friction acting on the table is 10 N to the left direction.
When inflating the balloon to a diameter of 7 inches, the final volume is
V₁ = (4/3)π*(7/2 in)³ = 57.1667π in³
When inflating the balloon to a diameter of 28 in, the final volume is
V₂ = (4/3)π*(28/2 in)³ = 3658.7π in³
If the rate of air entry into the balloon is constant, then
V₂/V₁ = 3658.7/57.1667 = 64
Answer: it takes 64 times longer.
