If a 0.55 kg tennis ball is struck by a tennis racket with 12 N of force pointing right, what will be the acceleration on the tennis ball? a. 12.55 m/s^2 to the left

b. 0.15 m/s^2 to the right

c. 11 m/s^2 to the left

d. 21.8 m/s^2 to the right

is there multiple choice answers?

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
