While performing an inspection on a government vehicle that will carry hazard class/division (hc/d) 1.1 and 1.2 materials, you notice that the vehicle's defroster does not work. the vehicle is going to be traveling for 1.5 hours during daylight conditions with no risk of cold weather. is this a cause for vehicle rejection?

Write the symbol for every chemical element that has atomic number greater than 3 and atomic mass less than 12.0 u.

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.

In a copper wire, a temperature increase is the result of which of the following
