Part A Older railroad tracks in the U.S. are made of 12-m-long pieces of steel. When the tracks are laid, gaps are left between the sections to prevent buckling when the steel thermally expands. If a track is laid at 16° C. how large should the gaps be if the track is not to buckle when the temperature is as high as 50° C? The coefficient of linear expansion of soft steel is 11 x 10-5 °C-1 Express your answer with the appropriate units. ? d = Value m Submit Previous Answers Request Answer

The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 68 kg (150 lb) person of height 1.83 m (6.0 ft) would have a body surface area of approximately 1.9 m². Part A What is the net amount of heat this person could radiate per second into a room at 19.0° C (about 66.2°F) if his skin's surface temperature is 31.0° C? (At such temperatures, nearly all the heat is infrared radiation, for which the body's emissivity is 1.0, regardless of the amount of pigment.) Express your answer in watts. ΑΣφ ?
