What is the most likely evidence of an energy transformation taking place when a skater glides over ice? A.Skating blades become
cold as kinetic energy is transformed into thermal energy B.Skating blades become cold as kinetic energy is transformed into gravitational energy C.Small tracks of water are left on the ice as kinetic energy is transformed into thermal energy D.Small tracks of water are left on the ice as kinetic energy is transformed into gravitational energy
The correct answer is C. The weight downward and the friction moving forward creates thermal energy through kinetics and melts a tiny bit of the ice making it slick enough for the skate to slide.
We are given with the total mass of fertilizer which is 14.1 oz. This is equivalent to 399.73 grams. 15% of the total is the amount of nitrogen. Thus, the nitrogen amount is 59.96 grams.
