You are in a rollercoaster that goes over a hump of radius 10 m at 50 mph. Luckily, there is a harness holding you in your seat, otherwise, you would have flown off. What is the force that the harness exerts on you at the top? Compare this force to your weight (i.e., how many times larger than your weight is it?)
Consider a reaction A+B=C has a rate = k[A][B]. The reaction rate is an experiment is carried out where [A]0=[B]0=1.00 M as well as the reaction rate is 0.24 Ms-1. Subsequent to 2.8 min, [A] = 0.60 M, explain what is the reaction rate then
