Hi hi guys! I am back with another scribe post for today. In class today, we first went over the two worksheets that were handed out on Monday called "Electric Potential" and "Physics 40S Electric and Magnetic Fields Assignment." Please click on the picture to see what the worksheets look like if you've missed it. You can ask Ms. Kozoriz for a copy if you didn't get one. If you want to see the steps on how to solve the problem, please come see me :). Otherwise, here are the answers for the worksheets if you can't read my writing:

Electric Potential

1.) 31 J/C (electric potential)

2.) a.) 3.6 x 10^-14 J (potential energy)

b.) 180 J/C (electric potential)

3.) 20,000,000 m/s (velocity)

4.) 3.0 x 10^-4 J (work)

5.) a.) 12 ev (work)

b.) 1.92 x 10^-18J ; 12 ev (energy)

c.) 2.05 x 10^6 m/s (speed)

Physics 40S Electric and Magnetic Fields Assignment

Part 1

Part 2

1.) a.) 3.2 x 10^-15 J (potential energy)

b.) 3.2 x 10^-15 J (kinetic energy)

c.) 8.38 x 10^7 m/s (velocity)

d.) 2.4 x 10^-10 s (time)

e.) 500,000 N/C (electric field)

f.) 8.78 x 10^16 m/s^2 (acceleration)

g.) 2.1 x 10^7 m/s (velocity)

h.) 2.5 x 10^-3 (displacement)

If you have any questions about the answers please come see me :).

Next in class, we were given 3 handouts. The handouts are "Moving Charges Worksheet," "Magnetic Formulae," and a cathode ray diagram that we previously got on Monday. Please click on the pictures to view the handouts.

Moving Charges Worksheet

Part 1

Part 2

Magnetic Formulae

Cathode Ray Diagram

It will be most likely that we will be correcting "Moving Charges Worksheet" tomorrow in class so for those who were in class please have it done and for the absentees, please see Ms. Kozoriz to get a copy.

Basically in today's class, we spent our time correcting the worksheets and were to work on the new ones that were handed out. New material was not taught in today's class so nothing important was missed. If you have any questions, please see Ms. Kozoriz or myself and we will be glad to help you.

Thanks for reading my post :)!
