Answer 1

Question

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .

A pulsar may form when a star of medium mass dies. On July 4, 1054 CE, Chinese astronomers witnessed the death of a star that led to the formation of the pulsar in the Crab Nebula. Contemporary astronomers have measured the angular speed of the nebula's pulsar as ? = 1.89 ✕ 102 rad/s and have found that the pulsar is slowing down such that ? = 2.39 ✕ 10−9 rad/s2. (a) Determine the period of the pulsar's rotation. s(b) Determine the number of seconds by which this period increases each second (dT/dt).

A star has a mass of 1.5 x 10^30 kg and is moving in a circular orbit about the center of its galaxy. The radius of the orbit is 2.2 x 10 ^ 4 light years( 1 lightyear = 9.5 x 10 ^15 m ) , and the angular speed of the star is 2.2 x 10 ^ -15 rad/s. a) Determine the tangential speed of the star. b) What is the magnitude of the net force that acts on the star to keep moving around the center of the galaxy?

A star rotates in a circular orbit about the center of its galaxy. The radius of the orbit is 2.9 x 10^20 m, and the angular speed of the star is 9.7 x 10^-15 rad/s. How long (in years) does it take for the star to make one revolution around the center? Note: the tolerance is in the 2nd significanct digit and indicate the unit
