You rapidly swirl a mixture of substances with different densities in a centrifuge, what will happen?

Asmall metal bar, whose initial temperature was 10° c, is dropped into a large container of boiling water. how long will it take the bar to reach 70° c if it is known that its temperature increases 2° during the first second? (the boiling temperature for water is 100° c. round your answer to one decimal place.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)

How are calculation for velocity and speed different

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
