Answer:
Why do insects fly so high?
Because the angle of attack is so high, a lot of momentum is transferred downward into the flow. These two features create a large amount of lift force as well as some additional drag. The important feature, however, is the lift.
Why an Aeroplane flying has kinetic
A flying aeroplane has potential energy has it flies above the ground level. And since the aeroplane is flying motion is associated with it and thus possesses kinetic energy. Hence a flying aeroplane has both potential and kinetic energ

Answer:
<em>The sale price is $498,30</em>
Explanation:
<u>Percentages</u>
The selling (list) price on a dishwasher is $906.
The store advertises a 45% markdown on that price.
The markdown is calculated as follows:
45% of $906 = 45 * 906 / 100 = $407.70
The sale price (retail) is calculated as the selling price minus the markdown.
Thus, the sale price is:
$906 - $407.70 = $498,30
The sale price is $498,30
It's always a good idea to start with the definition of the thing you're trying to find.
This problem is just trying to find out whether you KNOW the definition of acceleration. You may know it, but you haven't used it yet.
Average acceleration = (change in velocity) divided by (total time).
Change in velocity = (end value) minus (start value)
Change in velocity = (20m/s) - 0
Change in velocity = 20 m/s
Time = 10 s
Average acceleration = (20m/s)/(10s)
Average acceleration = 2 m/s^2
