Apply:
wavelength = speed of wave / frequency
wavelength = 12 m/s / 4 Hz = 48 m
When a conductor is passed through a magnetic field, a current is induced in the CONDUCTOR.
This process is called electromagnetic induction. Electromagnetic induction involves the production of electromotive force in an electrical conductor in a magnetic field. Electromagnetic induction can be generated using two different methods:
1. By keeping the electric conductor in a moving magnetic field.
2. By keeping the electric conductor in constant motion in a static magnetic field.
Newton’s second law is that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
Answer:
3.24 m/s
Explanation:
Suppose that the boat sails with velocity (relative to water) direction being perpendicular to water stream. Had there been no water flow, it would have ended up 0m downstream
Therefore, the river speed is the one that push the boat 662 m downstream within 539 seconds. We can use this to calculate its magnitude
So the boat velocity vector relative to the bank is the sum of of the boat velocity vector relative to the water and the water velocity vector relative to the bank. Since these 2 component vectors are perpendicular to each other, the magnitude of the total vector can be calculated using Pythagorean formula:
m/s
