Answer:
Spun yarns are produced by placing a series of individual fibres or filaments together to form a continuous assembly of overlapping fibres, usually bound together by twist. This operation is required in wool spinning because different parts of the fleece contain fibres of different length and thickness.
The wheel and axle is a simple machine that reduces the friction involved in moving an object, making the object easier to transport. ... Once the object is moving, the force of friction opposes the force exerted on the object. The wheel and axle makes this easier by reducing the friction involved in moving an object.
In addition to reducing friction, a wheel and axle can also serve as a force multiplier, according to Science Quest from Wiley. If a wheel is attached to an axle, and a force is used to turn the wheel, the rotational force, or torque, on the axle is much greater than the force applied to the rim of the wheel.

Answer:
15.782828 Miles
if that isnt what your asking for please tell me
Explanation:
Answer:
196J or 200J
Explanation:
Potential Energy = mgh
m( mass) = 10gm
h ( height) = 2m
g = 9.8 or 10 m/s ^2 ( choose whichever one is taught to you, usually in my school its 9.8 if the value isn't given )
PE = 10 × 10 × 2 = 200 J
or
PE = 10 × 9.8 × 2 = 196 J
Hope it helps
