(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

answer; /// the above statement is (true);

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
