8. Design a circuit that has two resistors connected in parallel. Given that you have a 22.5 Ω equivalent resistance, calculate a power source voltage that will produce a current of 0.8 A. Record the resistance and voltage in data table 4. Use the instructions provided in step 1 to build the circuit.

9. Calculate the current through and voltage drop across each resistor, and record the values in data table 4.

10. Using the ammeter and voltmeter, determine the current through and voltage drop across each resistor. Record the values in data table 4.

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
