Given that the period of the moon’s orbit about the earth is 27.32 days and the nearly constant distance between the center of the earth and the center of the moon is 3.84 3 108 m, use equation 13.11 to calculate the mass of the earth. (b) why is the value you calculate a bit too large?

the higher the current the higher the mag field around it the higher the influence on the compass

more than, less

less than, more

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
