Dr. kibble is monitoring the position of a meteoroid as it approaches planet earth. he observes it through a telescope every 5.0 minutes and records its position in the table below.
time (min) distance from earth (km)
0.0 18,000
5.0 15,000
10.0 12,000
15.0 9,000
which of the following could be the graph of the meteoroid's remaining distance to earth through time?

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.
