Breanna connected a wire coil to a lightbulb to demonstrate that a moving magnet can cause a current to flow in a wire. Then she moved a bar magnet
first toward and then away from the wire coil. However, she could not make
the lightbulb light up. Which factor could explain this outcome?

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Gas cloud 1 is likely to form a star. gas cloud 2 is not. based on this information, match the given conditions with each cloud

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
