The principle of conservation of electric charge implies that:At any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node, or:The algebraic sum of currents in a network of conductors meeting at a point is zero.

The answer is (8C5*8!)/4!*2!Because we don't want to place two s together & there are 5 s in this word . So subtract 13-5=8 & we get the number of space required for 5 s & now the remaining characters are placed as 8! & 2 L & 4 E are considered to be one if they are together. So 2! & 4! are divide by the whole number.Hence the correct answer is (8C5*8!)/(4!*2!)

The general formula:a^3 + b^3 + c^3 = (a+b+c)(a^2 +b^2 +c^2 -ab-bc-ca) + 3abcAnd it is given that (a+b+c)=0So if 0*(a^2 +b^2 +c^2 -ab-bc-ca) it gives 0 & hence the equation becomesa^3 + b^3 + c^3 =3abca^3 + b^3 + c^3-3abc=0Hence Proved.Very Simple :)

A quadratic equation is an equation ion which the highest power of variable is 2. It can be written in the form :Ax^2+Bx+C=0Where A,B are coefficientsC is Constant & x is variable.

Ohms law is limited to calculating the relationship between volts, amps and resistance.

Limitations of this law:
1. Now, this law is valid for conductors only and that too at a constant temperature. The resistance of a conductor increases with temperature. Hence, for changing temperature the V-I graph for a conductor will be non-linear (not a straight line).

2. In case of insulators ohm’s law is not followed at all, insulators do not conduct at all. But, when a very high voltage is applied across an insulator dielectric break down occurs and all of a sudden current begins to flow.

3. Ohm’s law is not followed by semiconductors. The V-I graph has a steep rising at a particular voltage, which indicates that the material begins to conduct properly only after a certain voltage.

Vector's component is a vector as it has direction with it.It can't be a scalar.Its also right that a vevtor's component can't be add to the same vector.But you are forgetting one thing for eg: acos2A is break down into acoscos^2A - asin^2A.Then both these terms are added to form the original vector.

I think 120 degree is the angle which is needed .

A pure number is a unitless quantity and dimensionless quantites are those pure numbers which don't have any dimension other than 1.

Like unitless quantity are 1,2,3

Dimensionless quantity are  π, e, and φ.

In classical statistical mechanics, the equipartition theorem is a general formula that relates the temperature of a system with its average energies. The equipartition theorem is also known as the law of equipartition,equipartition of energy, or simply equipartition. The original idea of equipartition was that, in thermal equilibrium, energy is shared equally among all of its various forms; for example, the average kinetic energy per degree of freedom in the translational motion of a molecule should equal that of its rotational motions.

No,its not possible.For pursuing a M.tech a person should be B.tech.

Current is scalar as it doesn't need any direction to state itself.

Scalar are those physical quantites which doesn't need any direction but vector are those which needs a direction like Velocity.

It is spread by Aedes mosquito.Aedes is a genus of mosquito originally found in tropical and subtropical zones, but now found on all continents excluding Antarctica. Some species have been spread by human activity. Aedes albopictus, a most invasive species was recently spread to the New World, including the U.S., by the used tire trade.

The electron (symbol: e−) is a subatomic particle with a negative elementary electric charge.

An electron has no known components or substructure; in other words, it is generally thought to be an elementary particle.An electron has a mass that is approximately 1/1836 that of the proton. The intrinsic angular momentum (spin) of the electron is a half-integer value in units of ?, which means that it is a fermion. The antiparticle of the electron is called the positron; it is identical to the electron except that it carries electrical and other charges of the opposite sign. When an electron collides with a positron, both particles may be totally annihilated, producing gamma ray photons.

In physics, tension is the pulling force exerted by a string, cable, chain, or similar solid object on another object. It results from the net electrostatic attraction between the particles in a solid when it is deformed so that the particles are further apart from each other than when at equilibrium, where this force is balanced by repulsion due to electron shells; as such, it is the pull exerted by a solid trying to restore its original, more compressed shape. Tension is the opposite of compression. Slackening is the reduction of tension.

metastable state,  in physics and chemistry, particular excited state of an atom, nucleus, or other system that has a longer lifetime than the ordinary excited states and that generally has a shorter lifetime than the lowest, often stable, energy state, called the ground state. A metastable state may thus be considered a kind of temporary energy trap or a somewhat stable intermediate stage of a system the energy of which may be lost in discrete amounts. In quantum mechanical terms, transitions from metastable states are “forbidden” and are much less probable than the “allowed” transitions from other excited states.

There are many examples of metastable states in atomic and nuclear systems. Analysis of atomic spectra often reveals metastable states as relatively final energy levels to which electrons have cascaded from higher energy levels in the act of generating light. Light energy trapped for a time in metastable mercury atoms accounts for the many photochemical reactions of this element. Metastable states of atomic nuclei give rise to nuclear isomers that differ—in energy content and mode of radioactive decay—from other nuclei of the same element.

The outer electron orbital of silicon, like that of carbon, has four valence electrons. The 1s, 2s, 2p and 3s subshells are completely filled while the 3p subshell contains two electrons out of a possible six.

Yes,there is not any word like principal Physics.But maybe you were trying to ask particle physics or may be plasma physics.Just post your query again ?
