Q1. A 9.7 V battery is connected to a bulb whose resistance is 1.3. How many electrons leave the battery per minute?

Q2. How much work did the movers do (horizontally) pushing a 190-{rm kg} crate 11.2 m across a rough floor without acceleration, if effective coefficient of friction was 0.60?

Q3. A constant horizontal pull of 8.55 {rm N} drags a box along a horizontal floor through a distance of 18.4 {rm m}. Suppose that the same pull is exerted at an angle above the horizontal. If this pull now does 59.0 {rm J} of work on the box while pulling it through the same distance, what angle does the force make with horizontal?
