An electron of mass 9.11 x 10-31 kg has an initial speed of 3.40 x 105 m/s. it travels in a straight line, and its speed increases to 6.60 x 105 m/s in a distance of 5.80 cm. assume its acceleration is constant.
(a) determine the magnitude of the force exerted on the electron.(n)
(b) compare this force (f) with the weight of the electron (fg), which we ignored.
f/fg= ?

answer:

a

explanation:

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
