Why conserve water? Because fresh water is rare and the process to clean water is expensive; therefore it shouldn’t be wasted. The next time you are tempted to waste water, think of all poor people who can’t afford clean water. Many children die and suffer everyday from dehydration and water that are unclean. :(

You have a 16N sack of potatoes that you need to lift onto the kitchen counter. You set up a pulley system with a mechanical adv

natali 33 [55]

A force of 8 N will be required.

<h3><u>Explanation:</u></h3>

Mechanical advantage is defined as the ratio of output force from a system to the input force into the system. A machine which has the mechanical advantage more than 1 means it requires less force to give more force as output. Similarly, when the mechanical advantage for the machine is less than 1,it means more force is required to give to achieve a less one.

Here in the question, the mechanical advantage of the pulley is 2.

Output force required to pull the sack of potatoes upto kitchen is 16N.

Mechanical advantage = Output force / input force.

Or, 2= 16 / input force.

So input force = $16 / 2 =8.$

So a force of 8 N will be required to pull the pulley.
