Try increasing the resistivity of the resistor, rho. How does this change the "look" of the resistor? Describe how that relates to the formula you just write (direct, indirect etc.) What happens to the value of the resistance? Is this something that can be changed in a resistor that you would buy in a store to use in a circuit?

An open cart is moving along a straight frictionless horizontal track. when rain starts falling vertically into the cart, what happens to the speed of the cart?

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

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.
