From what height above the surface of the earth should an object be dropped to initially experience an acceleration of 0.54g? (G = 6.67  10-11 N  m2/kg2, Mearth = 5.97  1024 kg, Rearth = 6.38  106 m)
 
  A) 2300 km
  B) 1700 km
  C) 5400 km
  D) 2900 km

Question 2

Suppose that a rigid aluminum wire were to be strung out in a loop that just fits snugly around the equator (assuming a perfectly spherical Earth with a radius of 6.37  106 m).
 
  If the temperature of the wire is increased by 0.50C, and the increase in length is distributed equally over the entire length, how far off the ground will the wire loop be if it remained centered on the earth? The coefficient of linear expansion of aluminum is 24  10-6 K-1.
  A) 76 cm B) 760 m C) 76 mm D) 7.6 mm E) 76 m
