Show all steps. 1. The moon orbits the earth at a distance of 3.85 x 10^8m. Assume that this
distance is between the centers of the earth and the moon and that the
mass of the earth is 5.98 x 10^24 kg. Find the period for the moon's motion
around the earth. Express the answer in days and compare it to the length
of a month.

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
