What causes the pail to move in circular motion?
What causes the pail to move in circular motion? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the […]

What is the best solvent for recrystallization?
What is the best solvent for recrystallization? For a solvent pair, the first solvent should readily dissolve the solid. The second solvent must have a lower solubility for the solute and be miscible with the first solvent.

What is the shortest period of time?
What is the shortest period of time? Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule. That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes […]
What is the purpose of frequency table?
What is the purpose of frequency table? The frequency table records the number of observations falling in each interval. Frequency tables are useful for analyzing categorical data and for screening data for data entry errors. Note that we will refer to two types of categorical variables: Categorical and Grouping or Break. How do you know […]
