which is a correct step in scientific experiment involving acids and bases? Mixing two acids to form a neutral solution. using an indicator to measure the hydrogen ion concentration of a solution. Pouring acid into an indicator to measure the pH of the indicator. Dissolving an indicator is an acidic solution to increase its pH

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

inverse v=i*r
