Answer:
560nm
Explanation:
You can use the following expression for thin films:
where n is the index of refraction, d is the thicknes of the thin film and m is the order of the diffraction pattern. For keratin layers we can use n=1.40. For the longest wavelenth we use m =1.
Hence, we obtain:

in case you dont want to read the answer is B
Mass of the block = 2/g = 2/9.8 =0.204 kg.
Frictional force = mass * acceleration
a = F/ m where F is the frictional force = 2.4
a = 2.4/ 0.204 = 11.76 m/s^2
It depends on the indirect taxes and the share market values
Earth quakes are commonly found along fault lines or tectonic plates.
