Answer:
T = 0.607 seconds
Explanation:
Given:
Mass, M = 1.50 × 10⁻² kg
Radius, R = 5.50 × 10⁻² m
Now,
the time period in terms of moment of inertia is given as:
.....................1
where, T is the time period
g is the acceleration due to gravity
I is the moment of inertia
Now,
Moment of inertia, I is given as:

on substituting the moment of inertia in the equation 1, we get

or

on substituting the valeus, we get

or
T = 0.607 seconds
Hence, the time period is 0.607 seconds
I think you would be using a topographic Map, So the answer should be A
Answer:
W = 68 J
Explanation:
On a force vs displacement chart, work is the area under the curve.
The area under the curve can be divided into a rectangle and a triangle
W = Fd = (2 N)(12 - 0 m) + ½(13 - 2 N)(12 - 4 m) = 68 N•m = J
