Four points are labeled on a graph. Rank the slopes of the graph at the labeled points. Explain your reasoning.
Please show all work on now all work and explain your reasoning carefully for all questions in order to maximize the possibility of partial credit The spring shown in the diagram below is compressed 50cm and used to launch a 95kg physics student seated on a 5kg sled. Friction on the track is 4 0.15 on the shaded portions and negligible for the solid portions. The track's valley and hill consist of circular shaped segments of radius "R". a. What...

A pH vs. kcat study was done on HCBR and the resulting plot is found below. What is the likely amino that is responsible for the the observed pH dependency and in which type of catalysis is it most likely participating? Explain your reasoning for your answers to both parts of this question. Use the O_2 binding curves to the left to address the following: a. If the proximal histidine were mutated to...
Functions f and g are defined for all real numbers. The function f has zeroes at -2, 3, and 7; and the function g has zeroes at -3, -1, 4, and 7. How many distinct zeroes dose the product function f * g have? Explain and show your answer.

4. The aerodynamic behavior of a flying insect is to investigate in a water tunnel using a 10X scale model. The lift force F is believed to be a function of wing size L, flight speed u, flapping frequency w, fluid density P, and fluid viscosity u. Assume that air has a density 1/1000th and a dynamic viscosity 1/100th that of water. (a). List...
