Answer:
Δx = 6.33 x 10⁻³ m = 6.33 mm
Explanation:
We can use the Young's Double Slit Experiment Formula here:

where,
Δx = distance between consecutive dark fringes = width of central bright fringe = ?
λ = wavelength of light = 633 nm = 6.33 x 10⁻⁷ m
L = distance between screen and slit = 3.7 m
d = slit width = 0.37 mm = 3.7 x 10⁻⁴ m
Therefore,

<u>Δx = 6.33 x 10⁻³ m = 6.33 mm</u>
Answer:
10N
Explanation:
1. Every Action has an equal and opposite reAction.
2. If 10N of force is acted upon an wrench, then the wrench will react with an equal amount of force, but in the opposite direction.
Explanation:
I hesitate to articulate upon the highest degree of accuracy!
Explanation:
P.E=MGH
Where m is mass
Where G is Acceleration Due to Gravity
Where h is Height
So the parameters are M = 20kg
G = 9.8m/s
H = 0.5meters
P.E= 20x9.8x0.5
=98J.
So Ans. is A= 98J
His kinetic energy is converted to potential energy.
