Hi guys. I have a question, if someone could explain how to calculate this. The extinction of the dinousaurs is widely believed to be due to the impact of a very massive meteorite striking the sea, land or both. Consider a smaller meteorite of mass 4 million kg entering the atmosphere vertically at 15 km/s and impacting land in a vertical fashion. You are given that: 1 megaton of TNT is equivalent to 4.2 thousand million million joules 20 kilotons of TNT is the energy associated with the explosion of an atomic bomb The number of atomic bombs to which the meteorite impact would have been equivalent is approximately....

4. Suppose you are the manager of a firm producing maize flour according to the cost function: C(Q) = 0.5 Q2 40. Further assume that the output market for maize flour is competitive and the market price of a kilogram of maize flour is N$24.00.na. How many kilograms of maize flour should you process to maximize profits? nb. What is your level of profits? nc. What is the minimum price at which you will produce output (shut-down point). nnI really need help with this question !!
