Astone was thrown horizontally at a speed of 5.0m/s from the top of a cliff 78.4 m high

a. how long does it take the stone to hit the bottom of the cliff

b. how far from the base of the cliff does the stone strike the ground

c. what are the horizontal and vertical components of velocity of the stone as it hits the ground

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.
