Aspherical star of one solar mass and r = 0.5 solar radii rotates once every 60 days. at the end of its nuclear burning it collapses to a radius of 70 km. if 1/4 of the mass is lost in the collapse, what is the final period of rotation of the star? (the radius of the sun is 696,000 km.) (a) 0.157 s (b) 0.0393 s (c) 0.0175 s (d) 0.00983 s (e) 0.00162 s

The magnetic field inside a superconducting solenoid is 4.50 t. the solenoid has an inner diameter of 6.20 cm and a length of 26.0 cm. determine (a) the magnetic energy density in the field and (b) the energy stored in the magnetic field within the solenoid.

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
