Question: In electrolysis 96 500C of charge releases 1 mole of hydrogen atoms.
a. From this information show how to determine the charge-to-mass ratio of the proton. Clearly state any assumptions you make.
b. Suppose in measuring e/m of the electron you observed that electrons accelerated through a voltage acquire velocity of v = 0.03 c (where c is the speed of light in vacuum) and bend in the circle of radius r = 3cm in a magnetic field of B = 2mT. What would you determine e/m to be? (Your answer should be different from the accepted value.)
c. Explain why results like your answers to (a) and (b) implied to J.J. Thomson the existence of a new particle. What was it, and in what ways is it important?
A soccer ball is released from the top of a smooth incline. After 4.20 s the ball travels 11.1 m. One second later it has reached the bottom of the incline. Suppose the ball's acceleration is constant and decide its value ( m/s2)?
A rocket blasts off from a platform on a space station. An identical rocket blast off from free space. Considering that everything else is equal, will the two rockets have the same acceleration? define.

Determine the normal mode frequency of the Lagrangian, given by L=(1/2)(xdot2 +ydot2)-(1/2)(ω21x2+ω22y2)+ αxy ,where α is constant xdot =ydot means derivative with respect time.
An airplane is heading due south at a speed of 580 km/h. If a wind begins blowing from the southwest at a speed of 90.0 km/h (average), calculate (a) the velocity (magnitude and direction) of the plane, relative to the ground, and (b) how far from it..
