Step3: Enter your full question details hereHow much mass does a 100 - watt bulb dissipate (in heat and light) in one year? Pedaling a bicycle at full throttle, you generate 1/2 horsepower of useful power (1 horsepower = 746 watts). The human body is about 25 percent efficient; that is, 25 percent of the food burned can be converted to useful work. How long a time will you have to ride your bicycle in order to lose 1 kilogram by con - version of mass to energy? Express your answer in years. (Conversion factor inside back cover.) How can reducing gymnasiums stay in business? One kilogram of hydrogen combines chemically with 8 kilograms of oxygen to form water; about 10 joules of energy is released. A very good chemical balance is able to detect a fractional change in mass of 1 part in 108. By what factor is this sensitivity more than enough-or insufficient-to detect the fractional change of mass in this reaction? Show that for a particle of nonzero rest mass, the speed (as a fraction of the speed of light) is given by the expression What value does the speed v derived in part A take when the mass of the particle is zero, as is the case for a flash of light? Is this result the one you expect? The mass and energy of particles in beams from accelerators is often expressed in Gave, that is billions of electron - volts. Journal articles describing these experiments refer to particle momentum in units of Gave /c. Explain.
