You hold a ruler that has a charge on its tip 6 cm above a small piece of tissue paper to see if it can be picked up. the ruler has −14 µc of charge. the tissue has 5 g of mass. what is the minimum charge required to pick up the tissue paper?

q=1.4*10^{-9}C

Explanation:

Given data:

charge on ruler = -14μC

Mass of tissue is 5 g

To Know the minimum charge,  equate electrostatic force to weight  

we have F = W

so

putting all value in equation,

solving for q

or q=1.4*10^{-9}C

this means that the temperature of both substances will be equal

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
