Answer:
c. 307 nm
Explanation:
angular position of first dark fringe = λ / d , λ is wavelength and d is width of slit .
(40 x π ) / 180 = 410 / d
angular position of second dark fringe = 2 x λ / d , λ is wavelength and d is width of slit .
(60 x π ) / 180 = 2 x λ / d
Dividing these equations
60 / 40 = 2 x λ / 410
λ = 307.5 nm.

Because your taking a educated guess on what will happened if the track member drinks the energy drink
The force between the two objects is 19.73 nN.
<u>Explanation:
</u>
Any force acting between two objects tends to be directly proportional to the product of their masses and inversely proportional to the square of the distance between the two objects. And this kind of attraction force between two objects is termed as gravitational force.
So if we consider 
and 
as the masses of both objects and let d be the distance of separation of two objects. Then the force between the two objects can be determined as below:
As gravitational constant 
, = 20 kg and = 100 kg, while d = 2.6 m, then
Thus, we get finally,
As we know, nano denoted by letter 'n' equals to 
So the force acting between two objects is 19.73 nN.
Answer:
Alveoli
The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood.
