Amicrophone is attaced to a spring that is suspended from
theceiling. directly below on the floor is a stationary 440
hzsource of sound. the microphone vibrates up and down insimple
harmonic motiono with a period of 2.0 s. the
differnce between the maximum and minimum sound frequenciesdetected
by the microphone is 2.1 hz. ignorign anyreflections of sound in
the room and using 343 m/s for the speed ofsound, determine the
amplitude of the simple harmonic motion.

To solve this problem we will apply the concept related to the amplitude and the Doppler effect. The difference between the maximum and minimum frequency detected by the microphone would be given by the mathematical function

Here,

= Source Frequency

= Speed of microphone

v = Speed sound

Maximum speed of the microphone is

Now the amplitude is

Here T means the Period, then

A= 0.2605m

Therefore the amplitude of the simple harmonic motion is 0.2605m

it becomes positively charged by charging it

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
