If the voltage in a circuit is 120 volts and the circuit produces 1500 watts of power, whatis the resistance in the circuit?24. Suppose an electrician designs a circuit with 110 volts and a resistance of 10 ohms. Howmuch power will the circuit produce?FREE FALL For Exercises 25 and 26, use the following information.Assuming no air resistance, the time t in seconds that it takes an object to fall h feet can behdetermined by the equation t . 4Lesson 10-325. If a skydiver jumps from an airplane and free falls for 10 seconds before opening theparachute, how many feet does the skydiver fall?26. Suppose a second skydiver jumps and free falls for 6 seconds. How many feet does thesecond skydiver fall?Chapter 10 23 Glencoe Algebra 1
