Question # 3 In the following figure, XY is a see - saw of 4 metres length. It is pivoted at its midpoint Z.
calculate the anticlockwise moment, about a horizontal axis passing through Z, of a child of weight
230 Newton who sits:

X. Z. Y

a. At X
b. 0.5 m from X
X
c. At Y
d. At Z and explain why it is acting that way​

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds

Ibelieve your answer is b.hope this : )
