An electron of mass 9.11*10-31kg has an initial speed of 3.00*105m/s. It travels in a straight line and its speed increases to 7
.00*105m/s in a distance of 5.00cm. Assuming its acceleration is constant, (a) determine the magnitude of the force exerted on the electron (b) Compare this force (F) with the weight of the electron (Fg), which we ignored
The accumulation of excess electric charge on an object is called static electricity. ... An electric field surrounds every electric charge and exerts the force that causes other electric charges to attract or repel. Electric fields are represented by arrows showing the electric field would make a positive charge move.
It's important that we understand how the climate is changing, so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures
As the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning.
