A smooth surface hemisphere is fixed on a ground as shown in figure. From the topmost point of it, a small ball starts sliding with no initial velocity. Then the distance s between the center of base circle of hemisphere and the point where particle strikes the ground is

Amanometer is used to measure the air pressure in a tank. the fluid used has a specific gravity of 1.25, and the differential height between the two arms of the manometer is 34 in. if the local atmospheric pressure is 12.7 psia, determine the absolute pressure in the tank for the cases of the

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.
