aMeanwhile,Wongcharee and Eiamsa-ard, further investigated the heat enhancement performance of clockwise and counter-clockwise alternate-axes twisted tape (T-A). The results indicate these: (1) the friction factor associated by T-A is higher than that induced by typical twisted tape (TT), and...
When the velocity of an object is quadrupled, by what factor is its momentum changed? When we have friction from rolling, is the friction vector always in the opposite direction as the direction of motion? Explain. How does mass and acceleration affect force? How to find velocity with mass ...
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...
SAML also supports authorization, which defines a user’s privileges. The set of privileges assigned to an individual user typically depend on the user’s role or job responsibilities. SAML authorization tells the authenticating system what type of access each user is allowed to have. SAML simplifi...
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 over where and when you receive calls. A mobile workforce demands a flexible solution. Combining the pow...
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...
As a result, the friction force is no longer proportional to the velocity gradient, but rather to the square of the velocity. This is because the shear stress is now a function of both the velocity gradient and the velocity itself. The friction factor, as shown on the Moody chart, ...
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...
Individual particles do not have a temperature, they have a kinetic energy. To have a temperature, you need a very large number of particles acting as a single system. However, you are correct that the characteristic kinetic energy of the particles that evaporated were likely not too far bel...
However, when complex institutional systems are in question – in particular, where several systems interface – the assumption is rather more strained. The tax system is an example. Most agents probably have general information about tax levels, and act accordingly; but it is less likely they ...
