2. Two mylar balloons are rubbed against your head so they get a charge. The force of repulsion is measured to be 3.59x10^-3 N when placed 0.50 meters apart. What is the charge on each balloon? Where electrons moved onto or off of the balloons? How many?​

In a system, when potential energy decreases, then entropy also decreases. true false

Suppose while hauling rocks, you accidentally drop one. it breaks apart in flat, planar sections. what type of rock did you just drop? 20 points

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
