50 ! i'll mark you brainliest, , and a 5 star! answer this !
briefly describe what you think the world would be like if the amount of greenhouse gases in the atmosphere were reduced to levels like those during the ice age.

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.
