A wheelbarrow has wooden handles that are 3.5 feet long. The axle on the wheel is the fulcrum and is 0.5 feet from the end. What is the MA? You know you can probably lift 70
pounds without too much effort. How heavy of a wheelbarrow load can you lift?

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
