Calculate the work done to move an object of 50g in a circular path of radius 10cm

Work done = 0.31 J

Explanation:

Radius, r = 10cm = 0.1 m

Mass of the object, m = 50 g = 0.05 kg

Force, F = mg = 0.05 * 9.8

F = 0.49 N

Distance covered by the object = 2πr

Distance moved by the object = 2π*0.1 = 0.63 m

Work done = Force * Distance

Work done = 0.49 * 0.63

Work done = 0.31 J

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.
