How is mechanical advantage determined in a pulley system?

Physics
1 answer:
ratelena [41]3 years ago
7 0

Answer:

<h3>To calculate the mechanical advantage of a pulley you simply have to count the number of rope sections that support whatever object you are lifting (not counting the rope that is attached to the effort). For example, in a one pulley system the MA is 1. ... The more compound the pulley is the easier the load is to lift.</h3>

Which one of the following salts, when dissolved in water, produces the solution with a ph closest to 7.00? 110) a) kh co3 b) cs
s344n2d4d5 [400]

CsCl, when dissolved in water, produces the solution with a ph closest to 7.00.

<h3>What is pH?</h3>

In chemistry, pH, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution.

Acidic solutions (solutions with higher concentrations of H+ ions) are measured to have lower pH values than basic or alkaline solutions.

The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.

Solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic.

Solutions with a pH of 7 at this temperature are neutral (e.g. pure water).

The neutral value of the pH depends on the temperature – being lower than 7 if the temperature increases above 25 °C.

The pH value can be less than 0 for very concentrated strong acids, or greater than 14 for very concentrated strong bases.
