Answer;
the colors of light that plants require for photosynthesis
Explanation;
The color of light used for photosynthesis depends on the pigment in the plant. For example, green plants with chlorophylls and carotenoids have a maximum activity with violet-blue and red light.
White light contains various colors, including red, orange, yellow, green, blue, indigo and violet. When plants harvest light for photosynthesis, they only absorb a few colors and reflect the rest. Plants appear green because chlorophyll absorbs other colors and reflects green.
I can't see numbers here, so here are all the answers:
1) the frequency is c/λ = 3e8/556e-9 = 5.39e14Hz
2) light travels at <span>299,792,458 m/s. So in nanoseconds it's 0.299792458m. This is about 1/3 of a meter which is about one foot.
3) length is L = ct = (</span>299,792,458 m/s)(6e-15) = 1.799e-6m or 1.799μm
The resulting positive amplitude of the two waves after the superimposition is 4.30 cm.
<h3>
Amplitude of the waves</h3>
The amplitude of the waves is the maximum displacement of the wave. This is the vertical position of the wave measured from the zero origin.
After the superimposition of the two similar waves, the resulting amplitude will be less than the initial amplitude of the wave with the highest vertical height since the superimposition creates destructive interference.
Resulting amplitude of the two waves is calculated as;
A = 5.4 cm - 1.10 cm
A = 4.30 cm
Thus, the resulting positive amplitude of the two waves after the superimposition is 4.30 cm.

Answer:
B = 0.07 mT
Explanation:
q = 1.6x10^-19 coulombs
for the electron to pass through the field undeflected the magnetic force acting on it must equal the electrical force due to the electric field
electric force = Eq = 16000 * 1.6x10^-19 newtons
magnetic force = qvB = 1.6x10^-19 * 2.7x10^8 * B
16000 * 1.6x10^-19 = 1.6x10^-19 * 2.7x10^8 * B
B = 0.07 mT (milli tesla)
There's actually only one latitude implied by anything attached the question . . . Zero, since there are no choices listed.
That's brilliant ! Because zero latitude (the equator) IS the place on Earth where tangential speed is greatest.
Very clever !
