A balloon containing 546 cm\(^3\) of air is heated from 0°C to 10°C. If the pressure is kept constant, what will be its volume at 10°C?
Calculate the inductance L of the COIL in the circuit shown above
Calculate the electric potential at a distance of 20.0cm from a point charge of 0.015 C placed in air of permittivity. [ take \(\frac{1}{4\pi εâ‚€}\) = 9.0 x 10\(^9\)Nm\(^2\)C\(^{-2}\)]
A series R - L - C circuit is shown in the diagram above. Which of the following vector diagrams correctly represents the phase relationship among I, V, V\(_F\), V\(_C\), and V\(_L\), if V\(_C\) is greater than V\(_L\) and the symbols have their usual meaning?
If the current in the resistor R is 0.05 A, calculate the p.d across the inductor.
