What is the total cost (including the price of the bulbs) to run incandescent buibs for 3.0 years? constants compact fluorescent buibs are much more efficient at producing light than are ordinary incandescent bulbs. they initially cost much more, but last far longer and use much less electricity. according to one study of these bulbs, a compact bulb that produces as much light as a 100 w incandescent bulb uses only 23.0 w of power. the compact bulb lasts 1.00x10 hours, on the average, and costs $ 11.0 whereas the incandescent bulb costs only 76.0 g, but lasts just 750 hours. the study assumed that electricity cost 8.00 ¢ per kwh and that the buibs were on for 4.0 h per day. vπ ασφ 31 ? 805.92 dollars) submit previous answers request answen xincorrect; try again; 5 attempts remaining part b what is the total cost (including the price of the bulbs) to run compact fluorescent bubs for 3.0 years? aedb 7 dollar(s)

d) physical means can be used to separate the components of air.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
