By applying a force of 55 N, a pulley system can lift a box with a mass of 20.0 kg. What

Gnesinka [82]

The mechanical advantage of the pulley is 3.56

Explanation:

The Mechanical Advantage (MA) of a pulley system is given by

$MA=\frac{Load}{Effort}$

where

Load is the weight of the object lifted

Effort is the force applied in input

For the pulley in this problem, we have:

Effort = 55 N

While the load is the weight of the box of mass m = 20.0 kg:

$Load = mg = (20.0 kg)(9.8 m/s^2)=196 N$

Substittuing, we find the MA of the pulley:

$MA=\frac{196}{55}=3.56$

<span>because the substance in the potassium permanganate crystals are permeable to water, so that means it will dissolve instantly while poured into water </span>

If a horse does 4000 J of work over 20 m, how much force does the horse use?

Eduardwww [97]

If you take a look at the definition of work, you will get this formula:

$W=Fd \\ F= \frac{4000}{20} \\ \boxed {F=200~N}$
