Answer:
It is because the room is occupied with stuffs.
Explanation:
In a well furnished room there are things
like bed, cupboard, wardrobe and other stuffs, So they act as absorbing materials.
They absorb sound and do not give a chance to resounds.
Well, the spring constant is measured using the F=k∆x, where F is the force, k is the constant, and ∆x is the change in position. So if the mass is 1.98, the force (mxg) is 19.4. Thus the spring constant is 19.4/.0478(change in position). This equals 405.86.
Answer:
Nearest, the revolutions per minute will be 29.
Explanation:
Given that,
Radius of circle = 1 m
Acceleration a =g
We know that,
Angular frequency is defined as,

Where, n = number of revolutions in one second
We need to calculate the revolutions in one second
Using formula of centripetal acceleration

Put the value of a and ω


Put the value into the formula


We need to calculate the revolutions per minute
Using value for the revolutions per minute


Hence, Nearest, the revolutions per minute will be 29.
