An enzyme with a km of 1.2x10-4 m was assayed at an initial sustrate concentration of 0.02 m. by 30 seconds, 2.7 μmoles/liter of product had been produced. how much product will be present at (a) 3 min and (b) 5.3 minutes? (c) what percent of the original substrate is used up at (c) 3 min and (d) 5.3 minutes?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
