Astudent of mass m = 78 kg takes a ride in a frictionless loop-the-loop at an amusement park. the radius of the loop-the-loop is r = 20 m. the force due to the seat on the student at the top of the loop-the-loop is fn = 364 n and is vertically down. what is the apparent weight of the student at the bottom of the loop-the-loop?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
