Weight on a car's wheels The center of mass of a 1600 kg car is midway between the wheels and 1 m above the ground. The wheels are 4 m apart.
(a) What is the minimum acceleration A of the car so that the front wheels just begin to lift off the ground?
(b) If the car decelerates at rate g, what is the normal force on the front wheels and on the rear wheels?
When 1 ml of HNO3 is added to the original solution what are the concentrations of [Ag+] and [Cl-]? I thought that the concentrations would decrease in the latter question, since there is twice as much solution. But shouldn't Q = Ksp, and the equi..
