Answer:
The answer is within the picture.
Explanation:
Here's the formula for mechanical advantage.
It's very important, and you should memorize it:
Mechanical Advantage = (output force) divided by (input force) .
#1). Force that moves the object = output force = 550N
Force that it takes = input force = 200N
Use the formula:
(output force) divided by (input force) = 550N/200N = 2.75 .
#2).
#3).
#4).
#5).
#6).
#7).
#8).
#9).
#10).
All of the rest of the problems on the page tell you the input force
and the output force. They can be solved by using the same formula
to calculate the mechanical advantage, just like I did in #1).
I disagree with the first sentence of #11. But by the time you get there,
you'll be an expert in mechanical advantage, so you can investigate and
decide who's correct ... the sheet or me.
<span>The car would have traveled exactly one-half of the circumference of the track, since it would have gone from one extreme point to its opposite extreme point. This would be equal to (3.5 / 2), or 1.75 km. The northernmost point would be 1.75km away from the southernmost point.</span>
Answer:
the planes times in the air
Explanation:
When a paper airplane is thown the path it takes is not the same every time. So, measuring the distance between the points where the airplane took off and the point where is landed would not show the time the plane was in the air.
The weight also does not determine the time the plane was in the air.
So, the planes air time recorded with the stopwatch gives the time the plane was in the air and will indicate the best plane.
