A gold wire with dexameter 2.00 mm carries a current of 0.20 A. The number density of conduction elTo estimate the mean time τ between collisions for a conduction electron in the wire, assume that, between collisions, an electron moves with a constant acceleration a due to the electric field. Under this assumption, explain why the drift velocity should be vd ≈ 1 2 aτ . Then solve for the numerical value of τ

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

d. air pressure decreases as altitude increases.

it is a negative acceleration
