A girl is riding a bicycle at a constant velocity of 3.0 m/s along a straight road. At time t=0, she passes a boy sitting on a stationary bicycle. At time t=0, the boy sets off to catch up with the girl. His velocity increases from time t=0 until t=5.0s, when he has converted a distance of 10m. He then continues at a constant velocity of 4m/s. a. Draw the displacement-time graph for the girl from t=0 to 12s
b. On the same graph axes, draw the displacement-time graph for the boy
c. Using your graph, determine the value of t when the boy catches up with the girl.

the answer would be   dignified - apex

the amount of current in the coil

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
