Tags Friction Friction factor Velocity Jan 1, 2009 #1 gmax137 Science Advisor Education Advisor 3,079 3,466 There's a couple of recent threads on friction - rather than hijack those here's a new thread with a few questions I have. What I'm trying to understand is the relation...
The model suggests that firing costs lead to a strong adverse employment effect if unemployment is mainly caused by job rationing, whereas in labor markets driven by search frictions firing costs have only a negligible impact on employment. The paper tests this hypothesis using data on the ...
If the momentum of an object is tripled, its kinetic energy will change by what factor? How to find average force with momentum? How does mass and acceleration affect force? What are the units of linear momentum? What can the law of conservation of momentum predict?
(5)The average kinetic energy is the same for all gases at a given temperature, regardless of the identity of the gas and is proportional to the temperature of the gas. Answer and Explanation: The kinetic energy of any particle of massmis given by th...
With a VoIP system, you can even forward the DIDs to different continents, saving long-distance costs. VoIP helps direct-ins occur in the telephone network, and virtually, you won’t need to buy all new phones or hardware. 📱Better flexibility and mobility With DID, you have more control...
But if we factor in the above observation the difference comes out to be100-150 units per year. Which means a 3 star rated refrigerator will consume about 100-150 units more than a 4 star and similarly a 4 star rated refrigerator will consume 100-150 units more than a 5 star per year...
A smaller surplus may reduce friction between China, which is poised to become the world’s biggest exporter, and its major trading partners, the commerce ministry said Dec. 16. Disputes with the U.S. or Europe span shoes, tires, screws and the Obama administration’s complaint this week th...
The PV flux (or transport) across a given section S is: Z PVF ¼ q Q ~u Á n^ dS; ð3Þ S with n^ the surface unit normal vector. PVF has units of pvs sÀ1. Fig. 13 shows the PVF across the eastern exit of the Strait of Gibraltar (section S, see Fig. 12). ...
In physics, certain mechanical objects have the property that they can be stretched or compressed, and then return to their original forms. After a certain extent, some materials such as metal in a spring will reach its physical limits, and lose its elasticity....
How do you charge objects by friction and induction? If two spheres, each with a charge of 5C have a force between them of 25N, how far apart are they? What is the magnitude of electric field strength a distance of 14 meters from a 3 x 10^-6 coulomb charge? (Ignore the direction...
