Power = Work done / time
Work done = Force * Distance
= 300 N * 1.5 m = 450 J
Power = 450 / 0.75 = 600 Watts.
The paths of the light waves that interfere cause first-order lines to differ in length by the wavelength of the light.
The phenomenon of wave interference occurs when two waves meet while traveling in the same medium.
As the two light waves interfere in the first order they interfere by differing the consecutive lengths by the wavelength of the light. The wavelength of the light can be defined as the distance between identical points (adjacent crests) in the adjacent cycles of a wave signal propagated in space or along a wire.
Hence, it can be concluded that the paths of the light waves that interfere cause first-order lines to differ in length by the wavelength of the light.

Answer:
low powered radio frequency (RF) energy
Answer:
![\frac{d^{2}x }{d^{2}t }+\frac{k}{m}x+\frac{b}{m} \frac{dx}{dt}=0](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5E%7B2%7Dx%20%7D%7Bd%5E%7B2%7Dt%20%7D%2B%5Cfrac%7Bk%7D%7Bm%7Dx%2B%5Cfrac%7Bb%7D%7Bm%7D%20%5Cfrac%7Bdx%7D%7Bdt%7D%3D0)
Explanation:
The spring mass equation for the damped oscillation will be,
![F=-kx-bv](https://tex.z-dn.net/?f=F%3D-kx-bv)
Here, -bv is the damping term used in this b is damping constant, k is spring constant, x is elongation in the spring, F is the force.
![ma=-kx-bv\\m\frac{d^{2}x }{d^{2}t }=-kx-b\frac{dx}{dt}\\ m\frac{d^{2}x }{d^{2}t }+kx+b\frac{dx}{dt}=0\\\frac{d^{2}x }{d^{2}t }+\frac{k}{m}x+\frac{b}{m} \frac{dx}{dt}=0](https://tex.z-dn.net/?f=ma%3D-kx-bv%5C%5Cm%5Cfrac%7Bd%5E%7B2%7Dx%20%7D%7Bd%5E%7B2%7Dt%20%7D%3D-kx-b%5Cfrac%7Bdx%7D%7Bdt%7D%5C%5C%20%20m%5Cfrac%7Bd%5E%7B2%7Dx%20%7D%7Bd%5E%7B2%7Dt%20%7D%2Bkx%2Bb%5Cfrac%7Bdx%7D%7Bdt%7D%3D0%5C%5C%5Cfrac%7Bd%5E%7B2%7Dx%20%7D%7Bd%5E%7B2%7Dt%20%7D%2B%5Cfrac%7Bk%7D%7Bm%7Dx%2B%5Cfrac%7Bb%7D%7Bm%7D%20%5Cfrac%7Bdx%7D%7Bdt%7D%3D0)
Therefore the differential equation for the damped harmonic oscillator is,
![\frac{d^{2}x }{d^{2}t }+\frac{k}{m}x+\frac{b}{m} \frac{dx}{dt}=0](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5E%7B2%7Dx%20%7D%7Bd%5E%7B2%7Dt%20%7D%2B%5Cfrac%7Bk%7D%7Bm%7Dx%2B%5Cfrac%7Bb%7D%7Bm%7D%20%5Cfrac%7Bdx%7D%7Bdt%7D%3D0)
