A 500-turn circular loop 15.0 cm in diameter is initially aligned so that its axis is parallel to the Earth's magnetic field. In 2.77 ms the coil is flipped so that its axis is perpendicular to the Earth's field. If a voltage of 0.166 V is induced in the coil, what is the value of the Earth's magnetic field?

Question 2

Which of the following statements is true about the Maxwell speed distribution?
  a. A higher proportion of molecules have the root-mean-square speed than the average speed.
  b. A molecule of gas moving at the most probable speed has more kinetic energy than does the same molecule moving at the average speed.
  c. The mean speed and root-mean-square speed are different names for the same value.
  d. The distribution of molecules from largest to smallest goes 1) most probable speed, 2) mean speed, 3) root-mean-square speed.
