Given that in a square, length=width, let the length be L, the perimeter will be:
P=L+L+L+L=4L
but
4L=16x+24
thus the length of one side will be:
L=4x+6
hence the length of the perimeter is (4x+6) units and the width is (4x+6) units.

A tuning fork is struck and oscillates in damped harmonic motion. The amplitude of the motion is measured, and 3 s later it is f

attashe74 [19]

Answer:

C=0.46 s⁻¹

Step-by-step explanation:

The general equation for the damped harmonic system given as

$y=Xe^{-Ct}sin\omega t$

Where

A= Amplitude

$A=Xe^{-Ct}$

C=Damping constant

Lets take at time t= t₁, A= K

And at time t= t₁+3 s ,A= K/4

$A=Xe^{-Ct}$

$K=Xe^{-Ct_1}$ -----------1

$\dfrac{K}{4}=Ke^{-C(t_1+3)}$ -------------2

From equation 1 and 2

$Xe^{-Ct_1}=Ke^{-C(t_1+3)}$

$1=4e^{-3C}$

$e^{3C}=4$

$C=\dfrac{1}{3}\ln4$

C=0.46 s⁻¹
