An object at a distance of 6400km from the centre the earth weights 50 Newton
what will be its weight if
it is shifted to 12800 km from the center of the earth?

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

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.
