The trees come from a seed and grow to trees
In any complex resistance circuit, the voltage across any resistor in the circuit is always C) equal to the voltage source.
Green light.
In fact, wavelength of
corresponds to 500 nm. The spectrum of visible light goes from approximately 380 nm (corresponding to violet light) to 750 nm (corresponding to red light). Green is approximately in the middle, having a wavelength range between 495-570 nm, therefore 500 nm lies in this range.
K2C03 is Potassium Carbonate. It's a molecule.
<span>So we want to know how much light will a single polarizer stop. Since the polarizer intensity formula is I=I0cos^2(a), where I is the intensity, I0 is the initial intensity and a is the angle of the light's initial polarization direction and the axis of the polarizer. Also, the average of cos^2a is 1/2 so I=(1/12)*I0. and I/I0=1/2 or 50%. So the light that passes trough one polarizer has 50% of the initial intensity. And the correct answer is 50%.</span>
