A 2.10-kg hammer is transported to the Moon. The radius of the Moon is 1.74  106 m, its mass is 7.35  1022 kg, and G = 6.67  10-11 N  m2/kg2. How much does the hammer weigh on Earth and on the Moon?
 
  What will be an ideal response?

Question 2

If the mass of a 1.0-kg book could be entirely converted into electrical energy, how many kW  h of energy would that generate? (c = 3.0  108 m/s)
 
  What will be an ideal response?

These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
