Answer:
d / λ = 26.7
Explanation:
In Young's double slit experiment, constructive interference is described by the expression
d sin θ = m λ
In the case of destructive interference we must add half wavelength (λ/2)
d siyn θ = (m + ½) λ
Let's clear
d / λ = (m + ½) / sin θ
Let's calculate
d / λ = (2+ ½) / sin 5.4
d / λ = 5 / (2 sin 5.4)
d / λ = 26.7

Answer:
The potential energy of a 2 kg mass at a height of 40 meters is 784 J
Explanation:
Potential energy is that energy that a body possesses due to the height at which it is located and whose unit of measurement of the International System of Units is the joule (J).
The potential energy of a body is the result of multiplying its mass by its height and by gravity:
Ep=m*g*h
Potential energy Ep, is measured in joules (J), mass m is measured in kilograms (kg), gravity, g, in meters / second-squared (), and height, h , in meters (m).
In this case:
- Ep=?
- m= 2 kg
- g= 9.8
- h= 40 m
Replacing:
Ep= 2 kg* 9.8 * 40 m
Solving:
Ep= 784 J
<u><em>The potential energy of a 2 kg mass at a height of 40 meters is 784 J</em></u>
Electricity is the flow of electric charges. Hope this is correct and helps!!
