URGENT HELP NEEDED 40 POINTS Two forces act on a 27 kg mass to give it an acceleration of 29 m/s2 in the positive x
direction. If one of the forces acts in the negative y direction with a magnitude of 570 N, what is the magnitude of the second force?
Answer in units of N.

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.
