Answer: 1) 17.65 * 10^-12 C/V; 2) 0.68 V
Explanation: In order to calculate the capacitance of one cylinder capacitor we have to use the following expression:
where and b are the inner and outer radius of teh cylinder, respectively. L is length of the cylinder.
Finally we also kwn that C=Q/ΔV
then we have
ΔV =Q/C
ΔV = 12 * 10^-12/17.65*10^-12= 0.68V
Mass = Density * Volume
Density = 19.3 g/cm³
Volume = 24 cm³
Mass = Density * Volume = 19.3 g/cm³ * 24 cm³ = 463.2 g
Mass = 463.2 g
I don’t know the answer but try khan academy it’s very helpful with all subjects and is free
It’s going to be both answer A and B but if you can only answer one then it’s going to be B
