Answer:
n = 3
Explanation:
We know that the nth-order maximum for the Young's two-slit experiment is given by the following expression:
dsin(θ) = nλ
If two maxima concides we must have the relation:
nλ1 = mλ2 --- eq1
In this particular experiment
m = n+1
λ1 = 680 nm
λ2 = 510 nm
Replacing m in eq1 we have
nλ1 = (n+1)λ2
Solving for n we have:
n = λ2/(λ1-λ2)
Therefore:
n = 510/(680-510)=3
A. K20 is the correct answrr
The answer is True. Acceleration is a vector quantity.
<span>Having a wide knowledge of the nervous system and the of how the brain’s different parts collaborate to organize all our movements, senses thoughts, and emotions enable the medical assistants to handle the cognitive and behavioral complications in the patient. It helps them to deal with wounds and falls since the nervous disorder generally affects cognition and movement. Having a wide knowledge of how the nerve impulses are transmitted from the nervous system to the brain, when it is then converted into feelings such as pleasure, pain, cold or hot, the medical assistant will be able to take response immediately on the patient prior they start complaining of sensory indications, such as discomfort, irritating, and unresponsiveness.</span>
<h3><u>Given</u><u>:</u></h3>
Force,F = 100 N
Acceleration,a = 5 m/s²
