יז Two charges are located on the positive x-axis of a coordinate system. Charge g1
= 6 C, and it is 6cm from the origin. Charge q2 = -3.0 C, and it is 12 cm from the
origin. How large is the electric force exerted by these two charges on a third
charge, q3 = 5.0 C, located at the origin? (k = 9 x 109 Nm/C)

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?

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.
