Explanation:plants trap light used in splitting water into hydrogen ions and oxygen molecules
To find speed you have to divide distance by time. In this case:
5 meters➗3 seconds = about 1.66666666 and so on m/s.
You could round to 1.67 or 1.7 if you'd like.
Answer:
a)
b)
Explanation:
a)
The width of the central bright in this diffraction pattern is given by:
when m is a natural number.
here:
- m is 1 (to find the central bright fringe)
- D is the distance from the slit to the screen
- a is the slit wide
- λ is the wavelength
So we have:
b)
Now, if we do m=2 we can find the distance to the second minima.

Now we need to subtract these distance, to get the width of the first bright fringe :
I hope it heps you!
6,000 in scientific notation is 6 x 10^3.
6 x 10^3 = 6,000
