In "The Atwood Machine and Newton's Laws" lab,
1) Draw free body diagrams for the hanging mass m1 and any attached pulleys for each of the three investigations.
2) Using the free body diagrams, determine the tension expected in the strings. Compare ( percent difference) these tensions to the weights of hanging mass m2 for each case
3) What conclusions can you draw from this experiment?
Transverse waves with a speed of 46 meter per second are to be produced on a stretched string. Find the required tension in the string
Manufacturers of wire (and other objects of small dimensions) sometimes use a laser to continually monitor the thickness of the product. The wire intercepts the laser beam, producing a diffraction pattern like that of a single slit of the same wid..
In an X-ray scattering measurement the first order diffraction peak is observed at ? = 16.5°. What is the angle of the third order peak
Two hanging masses are connected by ropes to a 20 kg mass which sits on a frictionless table. find The amount of unbalanced force acting on the masses,
For the cellar of a new house, a hole is dug in theground, with vertical sides going down 2.40m. A concrete foundationwall is built all the way across the 9.60m width of the excavation. Find the forcethe water exerts on the foundation wall
A wire carries a current of 0.665 A. This wire makes an angle of 55.5° with respect to a magnetic field of magnitude 4.92E-5 T, What is the length of the wire
You put a mass on the end of a light string so that it forms a simple pendulum that swings back and forth with a period T. If you double the mass on the end of the string, the period of the pendulum will... A mass is oscillating up and down on the ..
What pressure is acting on the walls of drum
A coffee cup immersion heater utilizes a heating coil of resistance R= 8.5 Ohms. If a current of 12.9A passes through the coil, when operated at 110V determine the electrical power dissipated in the coil.
A hiker, who weighs 603 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3220 N, and rests on two concrete supports, one on each end. He stops 1/4 of the way along the bridge.
You sing into a well and find that the well resonates at frequencies of 220 Hz and 260 Hz with no resonances between these two frequencies. What is the depth of the well
Each of the three helicopter rotor blades is 5.20 mlong and has a mass of 280 kg. What is the kinetic energy of rotation
