Agaussian wave packet is associated with an electron localised at time t0 to within a distance of 10-10 m. show that this wave packet will have spread to twice its size after a time10-16 s. consider now a gaussian wave packet associated with a proton localised at time t 0 to within a distance of 10-14 m. find the time after which this wave packet will have doubled in size 2.7

Any color picture tube and electric field exerts a net force of magnitude 1.68x 10^-13 n on an electron the rest mass of an electron is 9.11 x 10^-13 what is the electron acceleration?

Aforce of 8,480 n is applied to a chart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
