Plants are responsible for a very important energy transformation, as shown. At left, a small grey circle is followed by an arrow pointing right to a large grey circle with a small white circle centered in it. The 4 arrows point to a vertical row of 4 images, 1 arrow per image. From top there are a medium sized grey circle with a small white circle centered in it, then a small grey circle, then another small grey circle, then another medium sized grey circle with a small white circle centered in it. Then comes + Energy. At the top of the vertical row of 4 images is the label Nucleus. At the bottom of the vertical row of 4 images is the label Nucleus. Which energy transformation does the picture best illustrate? radiant to chemical nuclear to mechanical chemical to thermal mechanical to chemical

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
