The acceleration of gravity on the moon is about 1.6 m/sec2. an experiment to test gravity compares the time it takes objects to reach a speed of 10 m/sec after being dropped from rest. how long does an object dropped on the moon have to fall compared to an object dropped on earth?
a. 1.6 times as long
b. 6.1 times as long
c. 9.8 times as long
d. 15.7 times as long

The step-down transformer gives a current of 10a at 24v if the primary voltage is 240v calculate the 1_primary current 2_the power input 3_the power output

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.

How does the electric potential energy between two charged particles change if one particle is reduced by a factor of 3? a. increased by a factor of 3 b. it is decreased by a factor of 9 c. it is reduced by a factor of 3 d. it is increased by a factor of 9
