If a graduated cylinder has a current water level of 30 ml and you add an object which causes the water level to rise to 53 ml, what is the volume of the object you placed in the water?

23L

Explanation:

Given that:

Initial volume of water = 30mL

Final volume of water after an object was placed on it = 53mL

The volume object added which resulted in a rise to 5mL will be :

Final Volume of object - Initial volume of object

53 mL - 30mL = 23mL

Hence, volume of object added is 23 mL

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

neither accurate nor precise.
