The meaning of JOULE'S LAW is either of two statements in physics: (1) the rate at which heat is produced by a steady current in any part of an electric circuit is jointly proportional to the resistance and the square of the current (2) the internal ener
THIS excellent little volume could be read not only with profit but also with pleasure by all students of physics from the school-boy stage upward. There is no better way of appreciating the meaning and value of a scientific principle than a study of the ways in which it was evolved, and...

Also, when the apple is one meter above its original position, say the floor, gravity would have gained the ability to do work on it. This ability, when measured in joules, is equivalent to one joule. Meaning, when you release the apple, the force of gravity, which is simply just the...

The dashed line denotes Y/Y0 = 1, meaning that there is no advantage of the additive if Y/Y0 \(\le\,\)1. The recovery yields were the average of three independent flash Joule heating (FJH) experiments (n = 3). g Scanning transmission electron microscopy (STEM) image of the...
1 calorie is equal to ___ joule.. Ans: Hint: First find out what is calorie and joule. Conclude that they are the units of the same quantity, yet they convey different information or meaning. Obtain the relationship between calories an...
This raises several questions: What is their respective contribution to the understanding of the historical emergence of the energy concept, and to the understanding of the very meaning of this concept? Are these accounts concurrent? Eventually, how can they help for the teaching energy? To ...
In comparison with stage one of reference21 the beam size of the pump was increased by a factor ≈2.7, while the pulse energy was increased by less than a factor 2, meaning that the fluence is more than halved here, thus further reducing the effects of thermal lensing. Finally, the ...
