Answer:
T ' = √2 T
Step-by-step explanation:
Given that
Time period = P
Frequency = T
We know that time period for pendulum given as
When the length become half then time period will become p'
L'=L/2
It means that time period will become 0.707 P.
We know that frequency T
T= 1 /P
T' = 1/P'
T'=√2/P
T ' = √2 T
Triangles with height and base
, with
have area
.
Such cross sections with the base of the triangle in the disk (a disk with radius 5) have base with length
i.e. the vertical (in the plane) distance between the top and bottom curves describing the circle
.
So when , the cross section at that point has base
so that the area of the cross section would be 6^2/2 = 18.
In case it's relevant, the entire solid would have volume given by the integral
