Apulsar is a rapidly rotating neutron star that emits a radio beam the way a lighthouse emits a light beam. we receive a radio pulse for each rotation of the star. the period t of rotation is found by measuring the time between pulses. suppose a pulsar has a period of rotation of t = 0.0820 s that is increasing at the rate of 9.84 x 10-7 s/y. (a) what is the pulsar's angular acceleration alpha? (b) if alpha is constant, how many years from now will the pulsar stop rotating? (c) suppose the pulsar originated in a supernova explosion seen 582 years ago. assuming constant alpha, find the initial t.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
