The two plates of a capacitor hold + 0.16 and - 0.16 Coulombs of charge, respectively, when the potential difference is 2.7 V. What is the capacitance? Give your answer in SI units. (keep 3 decimals)

An RC circuit, comprising a charged capacitor in series with a resistor and a switch, has R = 8.3 kOhm and C = 4.7 F (10^-6 F). The capacitor is at full voltage Vo at t = 0, when the switch is closed. How long in seconds does it take the capacitor to discharge to 1.0 percent of its initial voltage? Give your answer to 3 decimals.

A parallel plates capacitor is made of two metal plates each has an area of (4.000x10^-2) m² . The plates are separated by a distance of (1.90x10^-3) m. A dielectric material with dielectric constant of (6.500x10^0) is used to fill the volume between the two plates. What is the capacitance of this capacitor? Give you answer in the unit of F with 3 s.f.

Calculate the lowest possible uncertainty in the velocity for an electron, (mass 9.1110^-31kg) where the position is known to an uncertainty of 2.510^-11m. Give your answerin units of 10⁶ m/s to 3 decimals.

How much kinetic energy (to 3 sf) will an electron gain (in joules) if it falls through a potential difference of (7.18x10^0) kV in a TV tube?

How much energy in micro joules must a 8 V battery expend to fully charge a 10x10^-6F and a 5x10^-6 F capacitor when they are placed in parallel? (round your answer to an exact number)

Carbon-14 has an activity of 0.25 Bq per gram of carbon for living organisms. The half-life of ¹⁴C is 5730 years. If a sample of charcoal from an archeological dig yields a ¹⁴C activity of (5.00x10^-2) Bq per gram of carbon, how old is the material? Give your answer in the unit of years with 3 s.f.
