Assume that the wavelengths of photosyntheticallyactive radiations (PAR) are uniformly distributed at integernanometers in the r
ed spectrum from 675 to 700 nm.a. What are the mean and variance of the wavelength distributionfor this radiation?b. If the wavelengths are uniformly distributed at integernanometers from 75 to 100 nanometers, how do the meanand variance of the wavelength distribution compare to theprevious part? Explain.

Answer:
The magnitude will be "353.5 N". A further solution is given below.
Explanation:
The given values is:
F = 500 N
According to the question,
In ΔABC,
⇒
⇒
then,
⇒
⇒
Now,
The corresponding angle will be:
⇒
⇒
⇒
Aspect of F across the AC arm will be:
=
On putting the values of F, we get
=
=
Component F along the AC (in magnitude) will be:
=
