Jessica stretches her arms out 0.8 m from the center of her body while holding a 2.0 kg mass in of each hand. She then spins around on an ice rink at 1.2 m/s. a. What is the combined angular momentum of the masses?
b. If she oulls her arms in to 0.12 m, what is her new linear speed?

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

Match the lithification processes. 1. contact pressure causing grains to "grow" together 2. increase in density due to weight of overburden 3. precipitation of bonding agents between grains a. recrystallization b. cementation c. compaction

Type the correct answer in each box. use numerals instead of words. if necessary, use / for the fraction bar. in a survey conducted in an office, 60% of the sample respondents agreed that employees should have flexible working hours. if the margin of error is ±2%, the expected population proportion that wants flexible working hours is between __% and __%
