Before you begin titration, drops of indicator are added to the Erlenmeyer flask. This happens when preparing to measure pH change.
f = 40 Hertz
Explanation:
Velocity of a wave = frequency × wavelength
frequency = velocity/wavelength
20m/s = f × 0.50
20/0.50 = f
40 Hertz = f or f = 40 Hertz
Answer:
Explanation:
Mass is how much an object weighs . Volume is the amount of space the object takes up
