1ADDITIONAL PRACTICE QUESTIONSWITH SOLUTIONS INDICATEDNote to students: Some of you have e-mailed me asking for morepractice questions. This is my full digest.Questions that Iconsider essential are the “Tutorial Questions” and myrecommendation is to work them in the following order:TUTORIAL QUESTIONS “1 to 12”:3, 57, 58, 59, 60, 61, 31, 35, 42, 75, 76, 77Please remember that our enrollment in this class is over 700and I have other classes to take care of too (my workload inthis module is only 2 weeks) so please don't overwhelm me withe-mails about these.
Section 1: IntroductionThe next questions pertain to Video: Introduction1.The Great Laxey Wheel pumps water from a mine, transferring potential energy to the water.If thewater were to then hypothetically flow on its own back into the mine, what would happen to thatpotential energy?
2.Gravitational potential energy can be found with the formulaU=mghwhere g = 9.81 m/s2on earth.A similar formula exists for electrostatic potential energy,U=qEhwhere q represents charge and Erepresents electric field strength.Find the necessary potential energy an electron needs to gain torise a height of 1 meter within an electric field of 1 V/m.
3.(ASSOCIATED VIDEO TUTORIAL Q1)Two electrodes in vacuum have created an electric field.This electric field was measured at twopoints.The first point had a potential of +1 V and the second point was at 0 V.An electron isinitially at rest at the second point.i.The electron will obviously move towards the first point.What kinetic energy (expressed in eV)will the electron have at the second point?
