Answer:
b) increase.
c) decrease.
d) Fringe is said to be a missing fringe when interference maxima overlap with diffraction minima.
Explanation:
a ) Young's interference is the interference phenomenon related to the light waves. Interference is the superposition of light waves . It proved the wave nature of light . Interference can be either constructive or destructive.
b) If the distance between the two slits increases, the number of fringes also increases. d sinθ = m λ. Here d is the slit width and m is the order of fringes. It shows that as d increases, m also increases.
c) Similarly, as d decreases , number of fringes decrease.
d) Fringe is said to be a missing fringe when interference maxima overlap with diffraction minima.
Answer:
F = 1.63 x 10⁻⁹ N
Explanation:
Complete question is as follows:
The diagram below shows two bowling balls, A and B, each having a mass of 7.0 kg, placed 2.00 m apart between their centers. Find the magnitude of Gravitational Force?
Answer:
The gravitational force is given by Newton's Gravitational Law as follows:
F = Gm₁m₂/r²
where,
F = Gravitational Force = ?
G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²
m₁ = m₂ = mass of each ball = 7 kg
r = distance between balls = 2 m
Therefore,
F = (6.67 x 10⁻¹¹ N.m²/kg²)(7 kg)(7 kg)/(2 m)²
<u>F = 1.63 x 10⁻⁹ N</u>
