Jason knows that the equation to calculate the period of a simple pendulum is , where T is the period, L is the length of the ro

Brrunno [24]

<u>Answer-</u>

$\boxed{\boxed{L=\dfrac{g}{4\pi^2 f^2}}}$

<u>Solution-</u>

The equation for time period of a simple pendulum is given by,

$T=2\pi \sqrt{\dfrac{L}{g}}$

Where,

T = Time period,

L = Length of the rod,

g = Acceleration due to gravity.

Frequency (f) of the pendulum is the reciprocal of its period, i.e

$f=\dfrac{1}{T}\ \Rightarrow T=\dfrac{1}{f}$

Putting the values,

$\Rightarrow \dfrac{1}{f}=2\pi \sqrt{\dfrac{L}{g}}$

$\Rightarrow (\dfrac{1}{f})^2=(2\pi \sqrt{\dfrac{L}{g}})^2$

$\Rightarrow \dfrac{1}{f^2}=4\pi^2 \dfrac{L}{g}$

$\Rightarrow L=\dfrac{g}{4\pi^2 f^2}$

Susanna found a roll of fabric she want to use to make a pillow. The role head 3/4 of a yard of fabric left. Suzanne need 1/3 of

balu736 [363]

$\frac{1}{4}$ represents the amount of fabric Susanna needed.

Step-by-step explanation:

Given,

Remaining fabric = $\frac{3}{4}\ of\ yard$

Fabric Susanna needs = $\frac{1}{3}\ of\ remaining\ fabric$

Fabric Susanna needs = $\frac{1}{3}*\frac{3}{4}$

Fabric Susanna needs = $\frac{1}{4}\ of\ a\ yard$

$\frac{1}{4}$ represents the amount of fabric Susanna needed.
