A5.0-kg hollow cylinder of radius 0.37m rotates freely about an axle that runs through its center and along its long axis. a cord is wrapped around the cylinder and is pulled straight from the cylinder with a steady tensile force of 50 n . as the cord unwinds, the cylinder rotates, with no slippage between cord and cylinder.
a- calculate the work done by the tensile force as the cylinder rotates through 1000 rad
b- if the cylinder starts from rest, calculate its rotational speed after it has rotated through 1000 rad .

Which object is most likely represented by a dot?

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.
