Answer:
It will not change
Explanation:
The period of oscillation of a mass-spring system is given by
where
T is the period
m is the mass hanging on the spring
k is the spring constant
As we see from the formula, the period of oscillation does not depend on the amplitude of the motion: therefore, if we change the amplitude, the time for one oscillation will not change.
Answer:
Plutonium, has formula Pu with molecular mass 94
Explanation:
Answer:
The Height is H = 70.02 m
Explanation:
We are given that the
Initial length is = =
from what we are told in the question the circumference of the circle is =
This means that the Radius would be :
Let C denote the circumference
So
=>
We are told that 1-meter bar of steel that increases its temperature by 1 degree C will expand meters
Hence
The final length would be
Where T is the change in temperature is the Coefficient of linear expansion for steel
let denote the final length
So
Now the Height is mathematically represented as
