The total resistance in this circuit is ___ ohms.

The total resistance in this circuit is ___ ohms. The battery voltmeter should read volts.

Sorry i didn't put it under science it didn't give it as an option. Could somebody answer this question and explain how they got it? I would greatly appreciate it!

I will be giving 45 pts which is the maximium number. Thank You!

Let me know if you need the aswer choices.

Total Resistance Rt = 30 Ohms

Voltmeter Reading V = 300 Volts

Explanation:

Using the attached circuit diagram,

Total Resistance Rt = R₁ + R₂ + R₃

                                = 12 Ohms + 8 Ohms + 10 Ohms

                            Rt = 30 Ohms

Voltage V  = IR

where V = ?, I = Current = 10 Amperes, R = Resistance = 30Ohms

∴ V = 10 * 30

      = 300 Volts

explanation:

0.07 g/cm³

1.37 g/cm³

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
