Heat is the energy transferred in a process due to a difference in temperature. Heat is usually expressed using specific units like Joules or calories. These units of measurement can be interconverted using specific conversion factors.Answer and Explanation: ...
All matter consists of atoms, which, in turn, consist of protons, neutrons and electrons. Both protons and neutrons are located in the nucleus, which is at the center of an atom. Protons are positively charged particles, while neutrons are neutrally charged. Electrons are negatively charged, a...
The International System of Units is a global standard for expressing the magnitudes or quantities of important natural phenomena. Also referred to as the metric system, the System of Units is commonly abbreviated as SI, which comes from the original French name, Système international d'unités. ...
An agent is authorized to act on behalf of another person, such as an attorney or a stockbroker. People hire agents to perform tasks that they lack the time or expertise to do for themselves. A universal agent has wide authority to act on another's behalf, but a general agent or special...

In a static electric field, the work required to move per unit of charge between two points is known as voltage. Mathematically, the voltage can be expressed as, Where work done is in joules and charge is in coulombs. We can define voltage as the amount of potential energy between two ...
This is the definition of noise figure adopted by the IRE. Noise figure is generally a function of frequency but it is usually independent of bandwidth (so long as the measurement bandwidth is narrow enough to resolve variations with frequency). Noise powers Na and Ni of equation (1-2) are...
