Answer:
The answer is "
"
Explanation:
Please find the complete question in the attached file.

pi = pressure only at two liquids' devices
PA = pressure atmosphere.
1 = oil density
2 = uncertain fluid density

The pressures would be proportional to the quantity
cm from below the surface at the interface between both the oil and the liquid.


4.Use Ohm’s Law to determine the resistance in a circuit if the voltage is 12.0 volts and the current is 4.0 amps.
A. 8.0 ohms B. 48 ohms C. 3.0 ohms D. 12 ohms
Ohm's law is V=IR, or I=V/R, or R=V/I. (I= current, V= voltage, R= resistance.) Let's plug in our variables: V=12.0, I=4.0, R=? into the equation R=V/I. 12.0/4.0=3.0, so the resistance is 3.0 ohms.
Answer: approximately 50%
Explanation:
Answer: D. It is a SUSPENSION
Explanation:
SUSPENSION
This is a combination of two or more single substances. The properties of the components involved are not however changed or lost as is the case with compounds.
For this reason this mixture can be separated due to sedimentation or filtering.
After a few days, this occurs in the aqueous nickel sulfide because the solid nickel sulfide is separating from the water.
