Two cylindrical rods are identical, except that one has a thermal conductivity k1 and the other has a thermal conductivity k2. they are placed between two walls that are maintained at different temperatures TW (warmer) and TC (cooler). When the rods are arranged as in part a of the drawing, a total heat Q' flows from the warmer to the cooler wall, but when the rods are arranged as in part b, the total heat flow is Q. Assuming that the conductivity k2 is twice as great as k1 and that heat flows only along the lengths of the rods, determine the ratio Q'/Q. Express your answer as a number with no units.
Explorer is caught in a whiteout (in which snowfall is so thick that the ground cannot be distinguished from the sky) as returning to base camp.
How much work must be completed to accelerate a baton from rest to an angular speed of 7.79 rad/s about its center? Consider the baton to be a uniform rod of length 0.596m and mass 0.495kg.
A frictionless pulley has the shape of a uniform solid disk of mass 6 and radius 25 . A 1.90 stone is attached to a very light wire that is wrapped around the rim of the pulley.
End A of the bar AB rests on a frictionless horizontal surface, and end B is hinged. A horizontal force vec F of magnitude 107 {rm N} is exerted on end A. You can ignore the weight of the bar. What is the vertical component of the force exerted by..
A 2.80x 10^2 W electric immersion heater is used to heat a cup of water. The cup is made of glass and its mass is 3x10^2 g. It contains 250g of water at 15°C.
A potter's wheel having a radius 0.47 m and a moment of inertia 10.9 kg•m2 is rotating freely at 46 rev/min. The potter can stop the wheel in 7.0 s by pressing a wet rag against the rim and exerting a radically inward force of 68 N. Find out the effe..
The block is acted upon by its weight w=200lb, a horizontal force Q=600 lb and pressure P exerted by the inclined plane. The resultant R of these forces is up and parallel to the incline there by sliding the block up it. Establish P and R.
A train at rest emits a sound at a frequency of 1045 Hz. An observer in a car travels away from the sound source at a speed of 37 m/s. What is the frequency heard by the observer .
On a frictionless table, a glob of clay of mass 0.340kg strikes a bar of mass 1.44kg perpendicularly at a point 0.10m from the center of the bar and sticks to it.
Find the typical speed for a tsunami. (Note down that in the open ocean, tsunamis generally have amplitude of less than a meter, allowing them to pass ships unnoticed. As they approach shore, however, water depth decreases and the waves slow down. Th..
What is the average kinetic energy of an ideal gas.
Three point masses each of mass m are connected by two thin rods each of mass M and length L. The central mass is at an origin and the z-axis is directed out of the page.
