A harmonic wave travels in the positive x direction at 12 m/s along a taught string. A fixed point on the string oscillates as a function of time according to the equationy = 0.0205 cos(4t)where y is the displacement in meters and the time t is in seconds(a) What is the amplitude of the wave, in meters?(b) What is the frequency of the wave, in hertz?(c) What is the wavelength of the wave, in meters?

Amplitude, A = 0.0205 m

Frequency, f = 0.636 Hz

Wavelength, 18.84 m

Explanation:

Given that,

Speed of the wave along a taught string, v = 12 m/s

A fixed point on the string oscillates as a function of time according to the equation :

........(1)

Here, y is the displacement in meters and the time t is in seconds

The general equation of oscillation is given by :

............(2)

On comparing equation (1) and (2) we get :

(a) Amplitude, A = 0.0205 m

(b) Frequency of the wave,

(c) Velocity of the wave is given by formula as :

Since,

Hence, this is the required solution.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
