Two parallel-plate capacitors, 6.6 µF each, are connected in parallel to a 20 V battery. One of the capacitors is then squeezed so that its plate separation is 66.0% of its initial value. (a) Because of the squeezing, how much additional charge is transferred to the capacitors by the battery? µC

The boy of mass 30 kg is at r1= 2 meters from the fulcrum. of the girl is 45 kg, at what r2 must she sit so that they are balanced ?

(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.)

The ability to make things happen is also called a. heat b. force c. matter d. energy
