If the solvent front moves 54 mm from the baseline and a compound in the food dye being analyzed moves 32 mm from the baseline, what is the Rf value for the compound?
The mean solar flux at the Earth's surface is ~2.00 J*cm^-2*min^-1. In a nonfocusing solar collector, the temperature can reach a value of 85.0 C. A heat engine is operated using the collector as the hot reservoir and a cold reservoir at 298 K.

A specimen of aluminum having a rectangular cross section 10 mm x 12.7 mm (0.4 x 0.5 in.) is pulled in tension with having a 35,000 N (8000 lbf) force, producing only elastic deformation. Calculate the resulting strain.
The african elephant has developed the pinna or external ear that functions as a radiator-convector. The pinna can be modeled as a flat plat with air flow over it.
Water is circulating through a closed system of pipes in a two floor apartment. On the first floor, the water has a gauge pressure of 3.4X10^5 Pa and a speed of 2.1m/s. However, on the second floor, which is 4m higher, the speed of water is 3.7 m/
