A uniform rod of mass M = 14.0 kg and length L = 1.70 m has one end anchored to the floor by a hinge that allows the rod to rotate freely in the x-y plane. Magnitude of acceleration due to gravity is g = 10 m/s2. 4 pt Part A: What magnitude of force, F perpendicular to the rod must you apply to its other end to hold the rod steady at this angle θ = 65◦ ?

Which form of cell division creates the sperm and egg, resulting in half of the chromosomes as the other cells?

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
