2) If the centripetal force on an object in uniform circular motion is increased, what is the effect on (a) the frequency of rotation f (with r constant) and (b) f and r when both are free to vary

a) Frequency will increase

b)The f and r will vary similarly

Explanation:

from equation F=mω²r

ω=2πf

⇒Force, F is directly proportional to f and r

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

answer: (431,2)
