Use the graph to determine the velocity between 6 and 12 seconds. m/s what was the velocity over the entire trip? m/s

-2 m/s

0 m/s

Explanation:

I just did it

The velocity of the particle is -2 m/s

Explanation:

Velocity is defined as the ratio of displacement of a particle to the time taken by the particle. The units of velocity is meters per second.

The equation representing velocity of a particle is given as:

From the graph:

The particle has traveled a distance of 12 m in the downward direction in between 6 to 12 seconds.

Displacement of particle = -12 m

Time taken = 12 - 6 = 6 sec

Putting values in above equation, we get:

Negative side represents the particle is moving in downward direction.

Hence, the velocity of the particle is -2 m/s

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
