Explanation: see the attachment for answers
Average eed = Dis Distance e / T * i * m * e = micircle / 2 20 = pi r/20; =220/20; =11 m/s; ty = D Average velocityDispacement/time
=diameter eter / 20; =140/20; =7 m/s

Hi brother
I'm fine
How are you ?
Good evening
A cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above. Cyclones are characterized by inward-spiraling winds that rotate about a zone of low pressure.
