Answer:Stirring.
Explanation:Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.
Answer:
1/2m or 0.5m
Explanation:
The formula to find the speed of a wave is given by:
V = frequency x wavelength
To find the wavelength, make the wavelength the subject of the formula
Therefore, wavelength = velocity ÷ frequency
