Answer:

v = -3

Step-by-step explanation:

6v+3= -75v - 15 (16)

81v=  -243

then put it over -3 then

-243 over 81

Answer:

v = -3

Step-by-step explanation:

Step 1: Use the Distributive Property

6v + 3= -75v - 240

Step 2: Isolate v

81v = -243

Step 3: Simplify

v = -3

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}
