A spring has a natural length of 30 cm. If a 24-N force is required to keep it stretched to a length of 40 cm, how much work W is required to stretch it from 30 cm to 35 cm? (Round your answer to two decimal places.)
W = J

If 0.6 J of work are needed to stretch a spring from 9 cm to 11 cm and 1 J are needed to stretch it from 11 cm to 13 cm, what is the natural length of the spring?

There are two major tests of readiness for college: the act and the sat. act scores are reported on a scale from 1 to 36. the distribution of act scores in recent years has been roughly normal with mean µ = 20.9 and standard deviation s = 4.8. sat scores are reported on a scale from 400 to 1600. sat scores have been roughly normal with mean µ = 1026 and standard deviation s = 209. reports on a student's act or sat usually give the percentile as well as the actual score. the percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. tanya scores 1260 on the sat. what is her percentile (± 1)?
