The photograph shows one of the boats in a science club's toy boat race. All the boats were powered by identical rubber bands. Judges used stopwatches to time how long each rubber band took to unwind. The table shows some
of the data the judges collected.

Which boat experienced the greatest unbalanced force?

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
