Answer:
-2π ≤ ∅ ≤ 3π/2
0 ≤ ∅ ≤ π/2
Explanation:
In simple harmonic motion, the displacement and velocity vectors are as follows:
where ∅ is the phase angle. At t = 0, the initial displacement and velocity are
According to two equations, we need to find the ∅ values which makes both cosine and sine terms positive.
So, ∅ is in the range: [-2π, -3π/2] and [0,π/2]
Answer:
f = 5.63 x 10¹⁴ Hz
Explanation:
Given,
speed of light, c = 3 x 10⁸ m/s
wavelength,λ = 533 n m = 5.33 x 10⁻⁷ m
frequency, f = ?
using formula of frequency
c is the speed of light
f = 5.63 x 10¹⁴ Hz
hence, the frequency of the light is equal to f = 5.63 x 10¹⁴ Hz
Explanation:
The law of repulsion is given by Coulomb. The mathematical form of Coulomb law is given by :
...............(1)
Where
F is the force
k is the electrostatic constant
are electric charges
r is the distance between charges
The Newton's law of universal gravitation is given by :
..............(2)
G is the universal gravitational constant
From equation (1) and (2) it is clear that both law obeys inverse square law and both are of same type. So, the law of repulsion by Coulomb agrees with the Newton's law of universal gravitation.
