5 How do scientists know the exact spot where an earthquake begins?
scientists know the exact spot where an earthquake begins because they use a ritcher scale
When do scientists have to rely on estimate?
Scientists must rely on estimates when they cannot obtain exact numbers.
If scientists cannot obtain exact numbers they should rely on a?
answer
Are all atomic masses known exactly?
No. Atomic masses have to be determined by using measuring instruments, which means that they can never be determined precisely. Every measuring instrument has a limit to its accuracy. There is wide agreement that it is impossible to build a perfect measuring instrument. Scientists have constructed some amazingly accurate measuring techniques, but no exact ones.
