The Lorentz-Fitzgerald Contraction

The USS Enterprise approaches the planet Seti Alpha 5 at a speed of 0.800c. Captain Kirk observes an airplane runway on the planet to be 2.00 km long. The air controller on the planet says that the runway on the planet is how long?

Starting from E2=(pc)2 + (mc2)2, derive p=h/wavelength for proton. Then verify E*wavelength=constant for proton.

Starting from E2=(pc)2 + (mc2)2, derive p=h/wavelength for proton. Then verify E*wavelength for proton. All the 2's are squares, i didnt know how to type that since I dont have that key function on keyboard.

Calculate the speed of an electron whose kinetic energy is twice as large as its rest mass energy.

Calculate the speed of an electron ehose kinetic energy is twice as large as its rest mass energy. Express V in C ( light speed). (Relativistic kinetic energy) P.S. Please help me with this as detailed as possible so I can understand the entire process. Thank you.

Rim of a cast iron flywheel

The rim of a castiron flywheel is 0.5m wide and its inner and outer diameters are 1.8m and 2.6m respectivly.Calculate a)the moment of inertia lc of the rim about its geometric axis; b)the radius of gyration k. need detailed simplified solution,no shortcuts thanks....

[Prob 8.12] Determine the compressional force? What is the intake temperature in a Carnot engine?

Referring to a person, determine the compressional force in the spine when the person bends forward to lift a 300N object. The spine and upper body are represented as a uniform horizontal rod of weight 400N. The erector spinalis muscle attaches at a point two thirds of the way up the spine and the angle between the spine and this muscle is 13.0 degrees. ======================================== Answers: (a) 500 N (b) 550 N (c) 600 N (d) 650 N ################################################## The exhuast temperature of a Carnot heat engine is 350 degree C. What is the intake temperature if the efficiency is 25.0 percent? ================================================== Answer:... click for more
