Answer:
It is all determined by how many spaces and which way the decimal point moves.
Step-by-step explanation:
So here are two examples
<em>Example 1:</em>
500000.00
To write this in scientific notation you would move the decimal place to the left.
You would move it 5 digits to the left so the exponent of 10 would be 5
<em>Example 2</em>
0.0000042
Here to write this in scientific notation you move the decimal place to the right.
You would move it 6 digits to the right so the exponent would be -6
Answer:
The length of pendulum is 55.853cm
Step-by-step explanation:
We are given
the original pendulum completed one swing every 1.5 seconds
so, T=1.5 sec
now, we can use time period formula
l is the length of pendulum
g is acceleration due to gravity
now, we can plug values
and then we can solve for l
In cm
Put them all under one. so it would b 1/everything negative
Denote the circle of radius 
by 
. is simple and closed, so by Green's theorem the line integral reduces to a double integral over the interior of (call it 
):
is a circle of radius , so we can write the double integral in polar coordinates as
a. For 
, we have
b. Let 
denote the integral with unknown parameter ,
By the fundamental theorem of calculus,
has critical points when
If 
, then line integral is 0, so we ignore that critical point. For the other two, we would find 
.
