Question 2 Cars A and B are travelling in adjacent lanes along a straight road. At time, t = 0 their positions
and speeds are as shown in the diagram. If car A has a constant acceleration of 0.6 m/s2 and car
B has a constant deceleration of 0.46 m/s, determine when A will overtake B.
(VA)o = 13 ms1
A
(VB). = 20 ms
B
O
30 m
Question 3
Position vs. time graph of a car is given below. Sketch a graph of velocity versus time and a
graph of acceleration versus time corresponding to the graph of displacement versus time given
in the graph.
x (m)
t(s)​

unable to answer the rest since your question is incomplete

the area between the graph and the t axis

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
