The simple machine that is not correctly matched with its appropriate task is the inclined plane because there is no such big ramp that is as high as 1 storey building, the appropriate task would be Lifting a heavy box and moving it across a room. and for the pulley : <span>Moving a heavy box up to the second floor of a building.</span>
The right answer is B because a liquid can take the shape of anything its in but it has the same volume
Answer:

Explanation:
To calculate the average velocity we must know the distance traveled and do
. The distance traveled is
, so we need to calculate the acceleration, which, since it's uniform, is
. Putting all together:

The speed of a transverse wave( v) = 117.03 m/s
The formula we can use in this case would be:
v = sqrt (T / (m / l))
Where,
v = is the velocity of the transverse wave = unknown (?)
T = is the tension on the rope = 380 N
m = is the mass of the rope = 86.0 g = 0.086 kg
l = is the length of the rope = 3.1 m
Substituting the given values into the equation to search for the speed v:
v = sqrt (380 N/(0.086 kg /3.1 m))
v = sqrt (380 * 3.1/ 0.086)
v = sqrt (13,697.67)
v = 117.03 m/s
speed of a transverse wave( v) = 117.03 m/s
