Eli stands on a skateboard at rest and throws a 0.5-kg rock at a velocity of 10,0 m/s, Eli moves back at 0,05 m/s. What is the combined mass of Eli and
the skateboard? Include the unit,

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

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

it is reliable if two scientists recorded it
