8. Electron travelling though two horizontal plates In the diagram P1 and P2 are two parallel horizontal plates that are 12.7 mm apart in a vacuum and have a potential
difference of 169 volts maintained between them, the upper plate being positive. Also, there is a horizontal magnetic field
of 0.033 T as shown.

A horizontal beam of electrons is directed between the plates so that it is moving at right angles to the magnetic field as
shown.
The magnitude of the electric field between the plates, to two significant figures, is:

Question part points submissions used suppose that 2 j of work is needed to stretch a spring from its natural length of 26 cm to a length of 36 cm. (a) how much work is needed to stretch the spring from 28 cm to 32 cm? (round your answer to two decimal places.)

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.

Which sections of the heating curve illustrate this process?
