Describe how pH can be measured using universal indicator and a pH meter. Add a few drops of
to the solution. Record
the
change. Compare the colour to the indicator reference
Clean the pH meter using
record the pH. The pH meter will give a more
water. Place into the solution and
reading.

As a pendulum moves closer to the equilibrium position, how do the velocity, acceleration, and force change? the velocity decreases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration decreases, and the net force decreases. the velocity increases, the acceleration increases, and the net force decreases. the velocity decreases, the acceleration increases, and the net force increases.
