(ii) a 0.72-m-diameter solid sphere can be rotated about an axis through its center by a torque of 10.8 m • n which accelerates it uniformly from rest through a total of 160 revolutions in 15.0 s. what is the mass of the sphere

Explanation:

As we know that it will have constant torque on it

so the acceleration of the ball will be constant so here we can say that we can use kinematics equation

so we have

now we know that

so we know that

here we know that

diameter = 0.72 m

so radius (R) = 0.36 m

it doesn't. it was imagined up in the middle ages.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
