Suppose you are in charge of a toll bridge that costs essentially nothing to operate. the demand for bridge crossings (q) is given by p = 15 – (1/10) q. the number of bridge crossings if the toll price were set to zero (p = $0) is and the loss in consumer surplus (cs) associated with a bridge toll of $5 (p = $5) is

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

In an experiment, how can i change human errors? be specific.
