The constant lair in the atmospheric law plays the role of a characteristic length. inphysics we always look for such characteristic parameters, because, although the constant temperature and thermal equilibrium assumptions are too simplistic for what is actually going on in the atmosphere, the value of lairstill gives an estimate of a height where theatmosphere undergoes a characteristic change. determine the value oflair. how does thisvalue compare with the altitude planes fly, clouds rise, and the structure of the troposphere?

When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.
