see how a block and tackle system can increase your mechanical advantage. you will need two broomsticks, a rope, and two . a. give each a broom stick and have them stand facing each other holding the broomstick firmly in both hands in a horizontal position. the broomsticks should be at the same level, about two feet apart. b. tie one end of the rope to one of the broomsticks. (you may need to have one of your hold the knot firmly in one hand as he or she holds the broomstick to anchor it.) c. wrap the rope around the other broomstick, as in a simple pulley system, and pull on the free end of the rope. your should resist your pulling. what happens? can you pull the broomsticks together? d. now weave the rope back over the first broomstick, so you have a double pulley. pull on the free end. what happens now? can you pull the broomsticks together? what is your mechanical advantage? e. try weaving the rope over the broomsticks one or two more times. describe what happens, and state the mechanical advantage of each situation.

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.

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.
