1. The Atmos clock(the so-called perpetual motion clock) gets its name from the fact that it runs off pressure vacations in the atmosphere, which drive a belows containing a mixture of gas and liquid ethyl chloride. Because the power to drive these clocks is so limited, they must be very efficient. In fact, a single 60.0 W lightbulb could power 240 million Atmos clocks simultaneously. Find the amount of energy, in joules, required to run an Atmos clock for one day. Explain and draws.

An 80 kg astronaut has gone outside his space capsule to do some repair work. Unfortunately, he forgot to lock his safety tether in place , and he has drifted 5.0 m away from the capsule . Fortunately, he has a 1000 W portable laser with fresh batteries that will operate it for 1.0 h. His only chance is to accelerate him self toward the space capsule by firing the laser in the opposite direction. He has a 10-h supply of oxygen. How long will it take him to reach safety ?

One of the highest power lasers in the world sits on a table in the General Research Lab Building at Colorado School of Mines. It emits pulses that last approximately 19 fs, and contain 90 mJ of energy. "fs" indicates a femtosecond, which is 10−15 seconds. When the beam exits the laser, it is approximately 30 mm in diameter. Molecules begin to ionize when applied electric fields reach approximately 8.680e+09 V/m. To what diameter must the beam be focused to reach this electric field strength?
LED bulbs are much more efficient at producing light than are traditional incandescent bulbs. They initially cost much more, but last far longer and use much less electricity An LED bulb that produces as much light as a 100 W incandescent bulb uses only 12.5 W of power. The LED bulb lasts 15,000 hours, on the average, and costs £8.00, whereas the cost of an incandescent bulb was only £0.75, but it lasted just 750 hourS. Assume that electricity costs £0 122 per kilowatt-hour and that the bulbs are on for 4.0 h per day.
