2. for question 14.15 (p.674) [q14.17, p.657 of 3rd edition] in the text book, assume that the resistance for each limb is 200 ω and the resistance of the body trunk is 100 ω, draw a complete equivalent circuit only

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
