He is using the filtration method.
It’s a technique which is used for separation of solids and fluids by putting them through a medium which allows only fluid to pass through, leaving the solids (in this case the soil) alone.
The fluid that passed is called the filtrate.

A system initially has a pressure of 12 atm and a volume of 9 L. What is the volume if the pressure is decreased to 6 atm?
Evgesh-ka [11]

Answer:

<h3>The answer is 18 L</h3>

Explanation:

In order to find the volume , we use the formula for Boyle's law which is

P_1V_1 = P_2V_2

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the final volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question

P1 = 12 atm

V1 = 9 L

P2 = 6 atm

We have

V_2 =  \frac{12 \times 9}{6}  =  \frac{108}{6}  \\

We have the final answer as

<h3>18 L</h3>

Hope this helps you

sweet [91]
Okay so i think the answer to this is.

weight=mg

m=0.000100 g=9.80

so weight= 0.00980 kgm/s2
Hopefully thats correct (i am horrible at math)
