An object with mass 120 kg moved in outer space. When it was at location <15, -22, -3> its speed was 12.5 m/s. A single constant force <240, 400, -230> N acted on the object while the object moved to location <18, -29, -7> m. What is the speed of the object at this final location?
Two spherical objects are separated by a distance of 1.01 × 10-3 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of 1.83 × 10-20 N. How many electrons did it take to produce the charge on one of the objects?
Part One. (Four points apiece) 1. One very small uniformly charged plastic ball is located directly above another such charged ball in a test tube as shown in the figure. The balls are in equilibrium a distance d apart. If the charge on each ball is doubled, the distance between the balls in the test tube would become a. v2d. b. 2d. c. 4d. d. 8d. e. None of these. 2.

Three parallel wires that are each 500 m long and spaced 0.6 m apart, carry currents and exert forces upon each other. Wire #1 and wire #2 are both fixed in position and cannot move. Wire #3 can move, but will break if it experiences a force of 20 N or more. Wire #1 is carrying a current of 120 A to the left and wire #2 is carrying a current of 240 A to the right. A) What is...
