An adventurous archaeologist cros- ses between two rock cliffs by slowly going hand over hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (Figure 5.43). The rope will break if the tension in it exceeds 2.50 × 104 N. Our hero's mass is 90.0 kg. (a) If the angle 0 is 10.0º, find the tension in the rope. Start with a free-body diagram of the archaeologist. (b) What is the smallest value the angle 8 can have if 0 the rope is not to break?

How does the measure of the relative viscosity provide a measure of the transesterification process? Select one: The produced biodiesel has a much higher viscosity than the starting soybean oil. The produced glycerol binds with the produced FAMES, creating more viscous products. O As relative viscosity decreases, this indicates that the reaction is progressing as desired. The produced biodiesel has a much lower viscosity than the starting soybean oil.
