Document Summary
Phys 101: physics for the life sciences lecture 26: If there is no net torque on the system then, dl dt. A rigid rod of mass m and length particles of masses m1 and m2 are stuck on the end and rotates in a vertical plane with angular velocity . is pivoted without friction at it"s centre. Two l: calculate an expression for the angular momentum of the system. +m1+m2)] : calculate the magnitude of the angular acceleration of the system. A star has a period of 30 days for rotation about an axis that goes through its centre. After the star undergoes a supernova explosion, the stellar of mass m which originally (before it got compressed) had a radius of 1. 0 104 km collapses to a neutron star of radius 3. 0km . Assuming the mass of the core does not change, determine the period of rotation of the neutron star.
