Step-by-step explanation: Our first task in this problem is to setup variables representing <em>length</em> and <em>width</em> and we do that by using the second sentence.
<em><u>The length is twice the width</u></em>
So if we call our width <em>x</em>, that means that our length is 2 times <em>x</em> or 2x
Width of the rectangle ⇒ <em>x</em>
Length of the rectangle ⇒ <em>2x</em>
Before moving on, go ahead and draw a picture of your
rectangle so that you can visualize what's going on.
I have done this for you below.
We label our widths <em>x</em> and our lengths <em>2x</em>.
Now we can use the first sentence to setup our equation.
The perimeter of a rectangle is the distance
around the outside of the figure.
So if our perimeter is 60, that means that x + x + 2x + 2x = 60.
Simplifying by combining like terms, we get 6x = 60.
Now dividing both sides by 6, we find that <em>x = 10</em>.
Since <em>x</em> represents width, our width is 10.
Our length therefore with be <em>2(10)</em> or 20.
So our width is 10 and our length is 20.
Answer
Given,
Period of the Pendulum, T= 1 s
acceleration due to gravity, g = 9.8 m/s²
Length of Bob = 0.2482 m
Loss of time in the clock = 1.5 minutes/ day
Loss of time in 1 oscillation
=
= 0.001042
Hence, time period, T = 1 + 0.001042
T = 1.001042 s
a) Using Time period of oscillation formula
Free fall acceleration at the clock location = 9.77 m/s²
b) Length of pendulum bob to keep it perfect time
Hence, Length of pendulum bob is equal to 0.2475 m.
