An electron has velocity v with arrow = (25i hat + 45j) km/s as it enters a uniform magnetic field b with arrow = 64i hat μt.
(a) what is the radius of the helical path taken by the electron? mm
(b) what is the pitch of that path? mm
(c) to an observer looking into the magnetic field region from the entrance point of the electron, does the electron spiral clockwise or counterclockwise as it moves?
i. clockwise
ii. counterclockwise

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..

the bal will not change its velocity.

force tends to be low and long diustance masses are high
