An ideal transformer has 60. turns on its primary coil and 300. turns on its secondary coil. If 120. V at 2.0 A is applied to the primary, what voltage and current are present in the secondary?
 
  What will be an ideal response?

Question 2

You have discovered a new asteroid, which has a moon in an elliptical orbit around it.
 
  From a series of observations, you establish that the closest approach occurs when the moon is 51,000 m from the asteroid, the furthest separation is 102,000 m, and the speed of the moon at the point of closest approach is 7.50 m/s. What is the mass of the asteroid? G = 6.67 x 10-11 Nm2/kg2.A) 4.25  1016 kg
