A doorknob is a simple machine known as a wheel and axle has a mechanical advantage of one, so it's easier to turn, but the trade off is that is moves a shorter distance.
A. less than one
B. greater than one
C. the same as
D. none of the above

B.) Greater than one

(at least I am pretty sure I am sorry if I am wrong I tried my best)

Explanation:

I think it is greater than one because it moves a short distance but it still is very helpful. The doorknob doesn't do much it just turns over and opens up a door. But, a doorknob CAN do much more. A doorknob can lock and keep things that you don't want inside out. It can also keep a door closed.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
