A circuit contains a resistor, an inductor, and a capacitor. When an AC voltage is applied across the circuit, the impedance of

katen-ka-za [31]

Answer:

The impedance of the circuit depends on the angular frequency of the voltage source.

Explanation:

In a electric circuit, the magnitude of the impedance, is given by the following expression:

$Z = \sqrt{R^{2} + (Xl-Xc)^{2} (1)$

where R = Resistance

Xl = Inductive reactance = ω*L

Xc = Capacitive Reactance = 1/ωC

and ω = angular frequency of the voltage source.

So, it can be seen that the impedance depends on the value of the constants R,L and C, and on the angular frequency ω.

netineya [11]

Answer:

9500 kJ; 9000 Btu

Explanation:

Data:

m = 100 lb

T₁ = 25 °C

T₂ = 75 °C

Calculations:

1. Energy in kilojoules

ΔT = 75 °C - 25 °C = 50 °C = 50 K

$m = \text{100 lb} \times \dfrac{\text{1 kg}}{\text{2.205 lb}} \times \dfrac{\text{1000 g}}{\text{1 kg}}= 4.54 \times 10^{4}\text{ g}\\\\\begin{array}{rcl}q & = & mC_{\text{p}}\Delta T\\& = & 4.54 \times 10^{4}\text{ g} \times 4.18 \text{ J$\cdot$K$^{-1}$g$^{-1}$} \times 50 \text{ K}\\ & = & 9.5 \times 10^{6}\text{ J}\\ & = & \textbf{9500 kJ}\\\end{array}$
