To solve this problem it is necessary to apply the concepts related to the Period based on the length of its rope and gravity, mathematically it can be expressed as
g = Gravity
L = Length
T = Period
Re-arrange to find the gravity we have
Our values are given as
Replacing we have
Therefore the correct answer is C.

Answer:
λ = 6.61 x 10⁻⁷ m = 661 nm
Explanation:
From the Young's Double Slit experiment, the the spacing between adjacent bright or dark fringes is given by the following formula:
Δx = λL/d
where,
Δx = fringe spacing = 2.86 mm = 2.86 x ⁻³ m
L = Distance between slits and screen = 2.12 m
d = slit separation = 0.49 mm = 0.49 x 10⁻³ m
λ = wavelength of light = ?
Therefore,
2.86 x 10⁻³ m = λ(2.12 m)/(0.49 x 10⁻³ m)
(2.86 x 10⁻³ m)(0.49 x 10⁻³ m)/(2.12 m) = λ
<u>λ = 6.61 x 10⁻⁷ m = 661 nm</u>

Machine
We use various tools to perform different types of work in our daily life. The tools or simple devices used for making our work easier, faster and more convenient are simple machines.
Those tools or devices which make our work easier and convenient in the direction of the force is called simple machine.
Purpose of using simple machine
Simple machines are used to make our work easier in the following ways:
By multiplying force.
By changing the directions of force.
By transferring force from one point to another.
By increasing the rate of doing work.
