A cars is moving at 12 m/s and has a mass of 600 kg. What is the kinetic energy for the car? (Formula:KE= 1/2 MV2) 36,300J 43,200J 72,600J 86,400J

The isotonic saline solution described in part a is connected to an unknown solution via a semipermeable membrane, the unknown solution level drops. based on this information, what can be said about these two solutions?

Iwill give extra points to who gets this right

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.
