A car moves along an x axis through a distance of 300m, starting at rest (at x=0), and ending at rest (at x=500m). Through the first ¼ of that distance, its acceleration is 2.15 m/s2
. Through the
next ¾ of that distance, its acceleration is -0.810 m/s2.
.
Find A) the velocity after travelling ¼ of the total distance
B) the time of travelling ¼ of the total distance
C) the time of travelling the remaining ¾ of the total distance
D) the total time of the entire travel.
E) Plot the graph of x-t and v- t of the motion

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.

As the distance from a magnet increases, what happens to the magnet force?
