Atechnician connects one lead of a digital voltmeter to the positive ( ) terminal of the battery and the other meter lead to the battery terminal (b) of the starter solenoid and then cranks the engine. during cranking, the voltmeter displays a reading of 878 millivolts. technician a says that this reading indicates that the positive battery cable has too high resistance. technician b says that this reading indicates that the starter is defective. which technician is correct

a. technician b only
b. technician a only
c. both technician a and technician b
d. neither technician a nor technician b

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?
