Answer:
Volume of balloon = 1000 cm^3
Explanation:
The head of a normal person can be assumed as a sphere with radius 10 cm.
Volume of sphere , where r is the radius.
We have approximate radius = 10 cm.
Approximate volume of head
In the given options the closest value to the approximate volume is 1000 cm^3.
So, volume of head = Volume of balloon = 1000 cm^3
Answer:
Part a)
Part B)
percentage increase is
%
Explanation:
Part a)
As we know that the beat frequency is
after increasing the tension the beat frequency is decreased and hence the tension in string B will increase
So we have
Part B)
percentage increase in the tension of the string will be given as
now we have
so we have
so we have
percentage increase is
Answer:
Explanation: This is done using the equation:
Because the Radius is a know value. We have the following.
Which is:
