You have been called to testify as a as an expert witness in a trial involving a head-on collision car a weighs 1515 pounds and was traveling eastward car b weighs 1125 lb and was traveling westward at 46 miles per hour. the car locked bumpers and slide eastward with their wheels locked for 19.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be .750. how fast in miles per hour was car a traveling just before the collision? ​

Initially, scientists described atoms as the smallest particles of matter. however, smaller particles within atoms were discovered. how did the scientific world respond to this new information? by ignoring the new information because it went against a scientific law by discarding the old theory about atoms and making a new one by revising the theory that explained atoms to include this new information by designing new technology that would prove the new information was wrong

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
