A swimmer jumps from a diving board into a pool. What would a graph of the swimmer's potential energy and total mechanical energy look like?(1 point) Potential energy would increase, while total mechanical energy would remain constant.

Potential energy would remain constant, while total mechanical energy would increase.

Potential energy would decrease, while total mechanical energy would remain constant.

Potential energy would remain constant, while total mechanical energy would decrease.

Which process is directly affected by the absorption of the thermal energy from the sun?

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?
