A rod of length L0 moves with a speed v along the hor- izontal direction. The rod makes an angle of 0 with Copyright 2005 Thomson Learning, Inc. All Rights Reserved. respect to the x-axis. (a) Show that the length of the rod as measured by a stationary observer is given by L L0[1 (v 2/c 2 )cos2 0] 1/2. (b) Show that the angle that the rod makes with the x-axis is given by the expression tan tan 0. These results show that the rod is both contracted and rotated.

A20 cm long spring is attached to a wall. the spring stretches to a length of 22 cm when you pull on it with a force of 100 n. what is the spring constant

Acyclotron is used to produce a beam of high-energy deuterons that then collide with a target to produce radioactive isotopes for a medical procedure. deuterons are nuclei of deuterium, an isotope of hydrogen, consisting of one neutron and one proton, with total mass 3.34×10−27kg. the deuterons exit the cyclotron with a kinetic energy of 6.40 mev .a-what is the speed of the deuterons when they exit? b-if the magnetic field inside the cyclotron is 1.25 t, what is the diameter of the deuterons' largest orbit, just before they exit? c-if the beam current is 350 μa how many deuterons strike the target each second?
