Answer:
The work done by the force is 150 J.
(d) is correct option.
Explanation:
Given that,
The object moves from 0 to 15 m.
Displacement = 15 m
Suppose the graph shows this force as a function of the position of the object
We need to calculate the work done
According to graph,
W = area under the graph from 0 to 15
Where, h = height
b = base
Put the value into the formula
Hence, The work done by the force is 150 J.
Answer:
1.time zones
2.The coriolis effect
3. triangles
Explanation:
1. day and night happen at different times at different places; it's always day somewhere and night another.
2. the coriolis effect means freely moving things (like cannonballs or hurricane winds) are deflected to the right - but only if your north of the equator if you're south of the equator they're deflected left.
3. if you walk a certain distance and make three right angle you can successfully make a triangles with three 90 degree angles which is impossible on a flat surface.
