Answer:
a has a faster period
Explanation:
Period only depends on the length, irrelevant to the mass.
a has a shorter length, so has a small period, or faster.
Answer:
The moment of inertia of this sphere is
.
Explanation:
It is given that,
Mass of the sphere, m = 4.8 kg
Radius of the sphere, r = 22 cm = 0.22 m
Tangential force, F = 11.2 N
The moment of inertia of the uniform sphere is given by :



So, the moment of inertia of this sphere is
. Hence, this is the required solution.
