Which of the following statements are true regarding transformers? check all that apply.
in a transformer, if the primary coil contains more loops than the secondary coil, then it is a step-up transformer. a transformer converts mechanical energy into electrical energy. a transformer is used to increase or decrease a direct current voltage. a transformer is used to increase or decrease an alternating current voltage. in a transformer, if the secondary coil contains more loops than the primary coil, then it is a step-up transformer. in a transformer, the power input is less than the power output.

After the near spacecraft passed mathilde, on several occasions rocket propellant was expelled to adjust the spacecraft's momentum in order to follow a path that would approach the asteroid eros, the final destination for the mission. after getting close to eros, further small adjustments made the momentum just right to give a circular orbit of radius 45 km (45 Ă— 10^3 m) around the asteroid. so much propellant had been used that the final mass of the spacecraft while in circular orbit around eros was only 545 kg. the spacecraft took 1.04 days to make one complete circular orbit around eros. calculate what the mass of eros must be.
