If the electric field of a beam of light exceeds the breakdown value for air, the beam does not propagate through the air. The maximum electric field that can propagate through the air is 3.0 x 106 V/m. (a) What is the maximum amplitude of the magnetic field for this light wave. {0.01 T} (b) Calculate the intensity of this wave. {1.19 x 1010 W/m2} (c) Describe what possibly happens when the wave intensity is higher than this value.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

You throw a small rock straight up from the edge of a highway bridge that crosses a river. the rock passes you on its way down, 7.00 s after it was thrown. what is the speed of the rock just before it reaches the water 28.0 m below the point where the rock left your hand? ignore air resistance.

Explain what will happen if decomposers were apsent from a forest ecoysystem.
