Explanation Section 1: To determine: The impedance ( Z ) in the circuit. Answer: The impedance ( Z ) in the circuit is 5.7 × 10 2 Ω Explanation : Given Info: Resistance R is 200 Ω frequency f is 60 Hz voltage , Capacitance C is 5.0 μF and costs is $0 .080/kWh Formula to calculate the impedance is Z = R 2 + X C 2 Z is the impedance in the circuit, R is the Resistance, X C is the capacitive reactance, Formula to calculate the capacitive reactance is, X C = 1 2 π f C f is the frequency of the source, C is the capacitance, Use 2 π f C for X C in the above equation to find the expression for Z Z = ( R ) 2 + ( 2 π f C ) 2 Substitute 200 Ω for R , 60 Hz for f and 5.0 μF for C in the above equation to find Z Z = ( 200 Ω ) 2 + ( 2 π ( 60 Hz ) [ ( 5.0 μF ) ( 1 F 10 6 μF ) ] ) − 2 = ( 200 Ω ) 2 + ( 2 π ( 60 Hz ) ( 5.0 × 10 − 6 F ) ) − 2 = 5.7 × 10 2 Ω Thus, the impedance ( Z ) in the circuit is 5.7 × 10 2 Ω Section 2: To determine: The Power P in the circuit Answer: The Power P in the circuit is 8.9 × 10 − 3 kW Explanation : Given Info: Voltage at rms circuit output Δ V rms is 120.0 V , Resistance R is 200 Ω and the impedance ( Z ) in the circuit is 5.7 × 10 2 Ω Formula to calculate the Power P in the circuit P = I 2 rms R P is the Power in the circuit I rms is the rms current in the circuit

13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…
