A 9.5-kg monkey is hanging by one arm from a branch and is swinging on a vertical circle. As an approximation, assume a radial distance of 65 cm between the branch and the point where the monkey's mass is located. As the monkey swings through the lowest point on the circle, it has a speed of 2.2 m/s.
Find the magnitude of the centripetal force acting on the monkey.
Find the magnitude of the tension in the monkey's arm.
F ind 3-5 different types of vacuum pumps - explain how they work - explain where you would use them - explain their operating pressure - etc... I don't have a clear idea for the vacuum pumps, for any 3-5 types of vacuum pumps.
