A proton enters a region filled with a magnetic field B = B0k. The proton enters with a velocity v = 103
i + 2 × 102k m s−1
. Assume that i points toward the right of the page and k points toward the
top.
(a) Sketch the setup, show the relevant vectors/forces and the direction of the orbit of the proton.
(b) What is the frequency of the proton in its orbit? Or, how long does it take the proton to make
one orbit?
(c) The proton travels 10 cm along the field, how many turns does it make?

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

Matt is driving down 7th street. he drives 150 meters in 18 sec. assuming he doesn’t slow down or speed up, what is his speed?

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
