My worldview is someone who doesn't exist. Someone who isn't real but i want them to BE real. It's not possible to have someone who is alike you. Who is there for yo when you need them
We have that for the Question "In the same year, the average finishing <em>time</em> for U.S. women was 4 <u>hours </u>and 41 <em>minutes</em>. What was the average female speed in miles per <em>hour</em>?" it can be said that
The average female speed in miles per hour
From the question we are told
In the same year, the <u>average</u> finishing <em>time</em> for U.S. women was 4 <u>hours </u>and 41 <em>minutes</em>. What was the average female speed in <u>miles</u> per <em>hour</em>?
<h3>Average speed </h3>
This is defined as the collective <u>mean</u> of different travel <em>intervals </em>
Generally the equation for Speed is mathematically given as
V=\frac{Distance}{Time}
Therefore
For 4 <u>hours </u>and 41 <em>minutes=4.683hours</em>
This travels time was <em>obtained </em>over a series of distance
<em>Hence</em>
<em>Distance D</em>
The average female <em>speed</em> in miles per hour

Answer:
The magnitude of the resultant decreases from A+B to A-B
Explanation:
The magnitude of the resultant of two vectors is given by
where
A is the magnitude of the first vector
B is the magnitude of the second vector
is the angle between the directions of the two vectors
In the formula, A and B are constant, so the behaviour depends only on the function . The value of are:
- 1 (maximum) when the angle is 0, so the magnitude of the resultant in this case is
- then it decreases, until it becomes 0 when the angle is 90 degrees, where the magnitude of the resultant is
- then it becomes negative, and continues to decrease, until it reaches a value of -1 when the angle is 180 degrees, and the magnitude of the resultant is
