A see-saw is 6.50 m long and has its fulcrum in the middle. A 102 N kid sits on the right end and a 75.0 N kid sits 1.50 m in from the right end. How far from the left end must a 185 N kid sit to balance the see-saw?

What must be the same for any two resistors that are connected in series ? a. the potntial diffrence across each b. the rate at which charge moves through each c. the rate at which energy is used by each d. the resistance to the flow of charge of each

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.
