Physics simple harmonic and fluids
Note: In addition to the equations provided on Official Stalling Equations sheets, you may need the following relationships to answer certain problems in the 2nd Minitest. Equation of continuity: Bernoulli's principle: The position vs. time graph at right is for a simple harmonic motion along the x-axis. Use this graph to answer questions 1 to 4. The approximate amplitude of oscillations is: The approximate period of oscillations is: The approximate phase angle of oscillations is: Recall the connection between simple harmonic motion and the motion of a particle along a circular path with a constant speed. If the x vs. t plot shown above is for the circular motion (constant speed) shown at right, the radius of the path and the angular speed of the particle, respectively, are: Can't answer this question because the linear speed is not given. A simple pendulum made of a bob of mass 1 kg and a massless rope of length 10 m performs simple harmonic oscillations. If the maximum displacement of the rope from the vertical is 3 degree , the maximum kinetic energy of the pendulum is: The Challenger Deep in the Mariana Trench, with its depth of about 11,000 m (-36,000ft% is the deepest known point in the oceans. A submersible designed to dive to the Challenger Deep has a flat viewport of area 0.15 m2. If the average density of sea water is 1030 kg/m3 and the atmospheric pressure can be neglected, the minimum force this viewport must be able to withstand is: The figure at right shows four situations in which two immiscible liquids are in a U-tube. In which situation(s) is/are the liquids most likely NOT in static equilibrium? A solid sphere of mass M and density rhos sits fully submerged on the bottom of a tank containing a liquid of density rhol (Explanation / Answer
