A spacecraft is in a circular orbit of radius 3.3*104 km arounda 1.9*1030 kg pulsar. The magnetic field of the pulsar at that radial distanceis 1.6*102 T directed perpendicular to the velocity of the spacecraft. The spacecraft is 0.20 km long with a radius of 0.040 km and moves counter clock wise in the xy-plane around the pulsar.
a) What is the speed of the space craft?b) Compute the induced emf.c) Describe the hazards for astronauts inside any space craft moving in the vicinity of a pulsar.
On her way to visit Grandmother, Red Riding Hood sat down to rest and placed her 1.7-kg basket of goodies beside her. A wolf came along, at what angle was Red Riding Hood pulling
A metal ball with diameter of a half a centimeter and hanging from an insulating thread is charged up with 1020 excess electrons. An initially uncharged identical metal ball hanging from an insulating thread is brought in contact with the first ball,..

A deuteron is accelerated from rest through a 10-kV potential difference and then moves perpendicularly to a uniform magnetic field with B = 1.6 T. What is the radius of the resulting circular path
A particle of mass m is acted on by a conservative force scalar potential is Ax^2/2 with A>0 constant. (a) Write the Lagrange for the system, drive the equations of motion using Lagrange's equation, and name all conserved quantities.
q. a cannon tilted upward at 33 fires a cannonball with a speed of 99. at that instant what is the component of the
A 2.5-kg cart is rolling along a frictionless, horizontaltrack towards a 1.5-kg cart that is held initially at rest. Thecarts are loaded with strong magnets that cause them to attract oneanother. Thus, the speed of each cart increases.
