Work out how much energy is saved by changing the bumper - set of a 1 000 kg car from steel to alumin um, over an assumed life of 200,000 km . T he energy consumption per kg per km for a 1000 kg car powered by gasoline i s 2.1 x 10 - 3 MJ/ ( km * kg )

Which is an example of an exothermic process?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
