(a) the principle of aerodynamic convergence

(b) the centripetal force

(d) Conservation of kinetic energy

(e) None of these

Conservation of angular momentum

Answer: Option C.

Explanation:

The law of conservation of angular momentum expresses that when no outer torque follows up on an article, no difference in precise force will happen.

The law of conservation of angular momentum expresses that the angular energy of a body that is the result of its snapshot of latency about the hub of revolution and its rakish speed about a similar pivot, can't change except if an outside torque follows up on the framework.

Parker (73.2 kg) is being dragged down the hall with an applied force of 123 N. If the frictional force is 27.4 N, what is the c

levacccp [35]

Answer:

The coefficient of friction in the hall is 0.038

Explanation:

Given;

mass of the Parker, m = 73.2 kg

applied force on the parker, F = 123 N

frictional force, Fs = 27.4 N

the coefficient of friction in the hall = ?

frictional force is given by;

Fs = μN

Where;

μ is the coefficient of friction

N is normal reaction = mg

Fs = μmg

μ = Fs / mg

μ = (27.4) / (73.2 x 9.8)

μ = 0.038

Therefore, the coefficient of friction in the hall is 0.038

Lisa [10]

Answer:

when the radius is halved, F becomes 4 times

Explanation:

The formula is given by

$F = \frac{Gm1m2}{r^2}$

When r is halved:

$F = \frac{Gm1m2}{(1/2r)^2}$

=> $F = \frac{Gm1m2}{1/4 r^2}$

=> $F = 4(\frac{Gm1m2}{r^2} )$

This means when the radius is halved, F becomes 4 times
