Some students observe drops of oil falling from a pipette.
The students measure the time for 80 drops to fall from the pipette. The total time for these 80 drops to fall is 48 s.
Calculate the average time between two consecutive drops falling.
The students collect some drops of oil.
The students measure the volume of the oil they collect. State the term for the laboratory equipment that is suitable for measuring this volume accurately.
In a similar experiment, another student collects 0.35 kg of oil. Calculate the weight of this oil. (Take the gravitational field strength g=10 N/kgg = 10\text{ N/kg}g=10 N/kg)
