i) Heat Current: Heat current is the same in all the conductors. i.e., \(\frac{Q}{t}={{H}_{1}}={{H}_{2}}={{H}_{3}}=….={{H}_{n}}\)
\(\frac{{{K}_{1}}A\left( {{\theta }_{1}}-{{\theta }_{2}} \right)}{{{l}_{1}}}=\frac{{{K}_{2}}A\left( {{\theta }_{2}}-{{\theta }_{3}} \right)}{{{l}_{2}}}=\frac{{{K}_{n}}A\left( {{\theta }_{n-1}}-{{\theta }_{n}} \right)}{{{l}_{n}}}\),
ii) Equivalent thermal resistance: \(R={{R}_{1}}+{{R}_{2}}+{{R}_{3}}+{{R}_{4}}+….{{R}_{n}}\),
iii) Equivalent thermal conductivity: It can be calculated as follows, from \({{R}_{S}}={{R}_{1}}+{{R}_{2}}+{{R}_{3}}+….\),
\(\frac{{{l}_{1}}+{{l}_{2}}+…+{{l}_{n}}}{{{K}_{s}}}=\frac{{{l}_{1}}}{{{K}_{1}}A}+\frac{{{l}_{2}}}{{{K}_{2}}A}+….+\frac{{{l}_{n}}}{{{K}_{n}}A}\) \(\Rightarrow {{K}_{S}}=\frac{{{l}_{1}}+{{l}_{2}}+…+{{l}_{n}}}{\frac{{{l}_{1}}}{{{K}_{1}}}+\frac{{{l}_{2}}}{{{K}_{2}}}+…..+\frac{{{l}_{n}}}{{{K}_{n}}}}\),
a) For n slabs of equal length, \({{K}_{S}}=\frac{n}{\frac{1}{{{K}_{1}}}+\frac{1}{{{K}_{2}}}+…..+\frac{1}{{{K}_{n}}}}\),
b) For two slabs of equal length, \({{K}_{S}}=\frac{2{{K}_{1}}{{K}_{2}}}{{{K}_{1}}+{{K}_{2}}}\),
iv) Temperature of interference of composite bar: Let the two bars are arranged in series as shown in the figure
Then heat current is same in the two conductors. i.e.,
\(\frac{Q}{t}=\frac{{{K}_{1}}A\left( {{\theta }_{1}}-\theta \right)}{{{l}_{1}}}=\frac{{{K}_{2}}A\left( {{\theta }_{1}}-\theta \right)}{{{l}_{2}}}\),
By solving we get, \(\theta =\frac{\frac{{{K}_{1}}}{{{l}_{1}}}{{\theta }_{1}}+\frac{{{K}_{2}}}{{{l}_{2}}}{{\theta }_{2}}}{\frac{{{K}_{1}}}{{{l}_{1}}}+\frac{{{K}_{2}}}{{{l}_{2}}}}\),
(a) If \({{l}_{1}}={{l}_{2}}\) then \(\theta =\frac{{{K}_{1}}{{\theta }_{1}}+{{K}_{2}}{{\theta }_{2}}}{{{K}_{1}}+{{K}_{2}}}\),
(b) If \({{K}_{1}}={{K}_{2}}\) and \({{l}_{1}}={{l}_{2}}\) then \(\theta =\frac{{{\theta }_{1}}+{{\theta }_{2}}}{2}\).

]]>The post Specific Heat of Solids appeared first on MyRank.
]]>For solids and liquids, we define the specific heat capacity as the quantity of energy that will raise the temperature of unit mass of the body by 1K. When a solid is heated through a small range of temperature, its volume remains more or less constant. Therefore, specific heat of a solid may be called its specific heat at constant volume\({{C}_{V}}\).
1) From the graph it is clear that at T = 0, \({{C}_{V}}\) tends to zero.
2) With rise in temperature, \({{C}_{V}}\) increases and at particular temperature it becomes constant = 3R = \(6cal/mole\times kelvin=25J/mole\times kelvin\),
3) For most of the solids, Debye temperature is close to room temperature.
4) Dulong and Petit Law: Average molar specific heat of all metals at room temperature is constant, being nearly equal to 3R =\(6\,cal.mol{{e}^{-1}}{{K}^{-1}}=25J.mol{{e}^{-1}}{{K}^{-1}}\), where R is gas constant for one mole of the gas. The statement is known as Dulong and Petiti law.
5) Debey’s law: It was observed that at very low temperature molar specific heat\(\propto \,{{T}^{3}}\).
6) Specific heat of ice: In C.G.S system, \({{C}_{ice}}=0.5\frac{cal}{gm\times {}^{0}C}\).
In S.I system, \({{C}_{ice}}=500\frac{cal}{kg\times {}^{0}C}=2100\frac{Joule}{kg\times {}^{0}C}\),
Solids have only one specific heat but whereas for fluids have two specific heats i.e., specific heat at constant pressure and specific heat at constant volume, because solids are very insensitive to change in volume under the application of external pressure.

]]>Theorem: If a transversal cut the sides BC, CA, AB of a triangle in D, E, F respectively then
BD/DC. CE/EA. AF/FB = -1.
Proof:
Let A (x₁, y₁), B (x₂, y₂) and C (x₃, y₃) be
Let the transversal be ax + by + c = 0
BD/DC = The ratio in which ax + by + c = 0 divides BC
= – (ax₂ + by₂ + c)/ (ax₃ + by₃ + c)
CE/EA = The ratio in which ax + by + c = 0 divides CA
= – (ax₃ + by₃ + c)/ (ax₁ + by₁ + c)
AF/FB = The ratio in which ax + by + c = 0 divides AB
= – (ax₁ + by₁ + c)/ (ax₂ + by₂ + c)
Therefore, BD/DC . CE/EA . AF/FB
= – (ax₂ + by₂ + c)/ (ax₃ + by₃ + c) . – (ax₃ + by₃ + c)/ (ax₁ + by₁ + c) . – (ax₁ + by₁ + c)/ (ax₂ + by₂ + c) = -1

]]>Theorem: If the lines joining any point P, to the vertices A, B, C of a triangle meet the opposite Sides in D, E, F respectively then (BD.CE.AF)/(DC.EA.FB)=1
Proof:
Let A (x₁, y₁), B (x₂, y₂), and C (x₃, y₃) be the vertices.
Let us consider point P is (0, 0)
We know that Slope of AB is (y₂ – y₁)/ (x₂ – x₁)
A (x₁, y₁) and P(0, 0)
Slope of AP is (y₁ – 0)/ (x₁ – 0)
= y₁/x₁
Equation of AP is y – 0 = y₁/x₁(x-0)
y = y₁/x₁(x)
yx₁ = y₁x
⇒ xy₁ – x₁y = 0
BD/DC = -(x₂y₁ – x₁y₂)/(x₃y₁ – x₁y₃)
= (- x₂y₁ + x₁y₂)/(x₃y₁ – x₁y₃)
Slope of BP is (y₂ – 0 )/(x₂ – 0)
= y₂/x₂
Equation of BP is y – 0 =(y₂/x₂)(x – 0)
y =(y₂/x₂)(x – 0)
yx₂ = y₂x
y₂x – yx₂ = 0
CE/EA = -(x₃y₂ – x₂y₃)/(x₁y₂ – x₂y₁)
= (x₂y₃ – x₃y₂ )/(x₁y₂ – x₂y₁)
Slope of CP is y – 0 =y₃/x₃(x – 0)
⇒ x₃y = y₃x
⇒ xy₃ – x₃y = 0
AF/FB = -(x₁y₃ – x₃y₁)/(x₂y₃ – x₃y₂)
= (x₃y₁ – x₁y₃)/(x₂y₃ – x₃y₂)
BD/DC. CE/EA. AF/FB = (- x₂y₁ + x₁y₂)/(x₃y₁ – x₁y₃) . (x₂y₃ – x₃y₂ )/(x₁y₂ – x₂y₁) . (x₃y₁ – x₁y₃)/(x₂y₃ – x₃y₂)

]]>The post Elastic Properties of Matter appeared first on MyRank.
]]>1) Elasticity: The property of matter by virtue of which a body tends to regain its original shape and size after the removal of deforming force is called as Elasticity.
2) Plasticity: The property of matter by virtue of which it does not regain its original shape and size after the removal of deforming force is called as Plasticity.
3) Perfectly Elastic body: If on the removal of deforming forces the body regain its original configuration completely it is said to be perfectly elastic. A quartz fibre and phosphor bronze is the nearest approach to the perfectly elastic body.
4) Perfectly Plastic body: If the body does not have any tendency to recover its original configuration, on the removal of deforming force, it is said to be perfectly plastic.
Paraffin wax, wet clay are the nearest approach to the perfectly plastic body. Practically there is no material which is either perfectly elastic or perfectly plastic and the behavior of actual bodies lies between the two extremes.
5) Elastic limit: Elastic bodies show their property of elasticity up to a certain value of deforming force. If we go on increasing the deforming force then a stage is reached when on removing the force, the body will not return to its original state. The maximum deforming force upto which a body retains its property of elasticity is called elastic limit of the material of body. Elastic limit is the property of a body whereas elasticity is the property of material of the body.
6) Elastic fatigue: The temporary loss of elastic properties because of the action of repeated alternating deforming force is called elastic fatigue.
Due to elastic fatigue:
i) Bridges are declared unsafe after a long time of their use.
ii) Spring balances show wrong readings after they have been used for a long time.
iii) We are able to break the wire by repeated bending.
7) Elastic after effect: The time delay in which the substance regains its original condition after the removal of deforming force is called elastic after effect. It is the time for which restoring forces are present after the removal of the deforming force; it is negligible for perfectly elastic substance, like quartz, phosphor bronze and large for glass fibre.

]]>The post Electrical Conducting Materials for Specific Use appeared first on MyRank.
]]>Electrical conducting materials are the basic requirement for electrical engineering products.
1) Filament of electric bulb: It is made up of tungsten which has high resistivity, high melting point.
2) Element of heating devices (such as heater, geyser or press): It is made up of nichrome which has high resistivity and high melting point.
3) Resistances of resistance boxes (standard resistances): Are made up of alloys these materials have moderate resistivity which is practically independent of temperature so that the specified value of resistance does not alter with minor changes in temperature.
4) Fuse – Wire: It is made up of tin – lead alloy (63% tin + 37% lead). It should have low melting point and high resistivity. It is used in series as a safety device in an electric circuit and is designed so as to melt and thereby open the circuit if the current exceeds a predetermined value due to some fault. The function of a fuse is independent of its length.
Safe current of fuse wire relates with its radius as \(i\propto {{r}^{3/2}}\)
5) Thermistors: A thermistor is a heat sensitive resistor usually prepared from oxides of various metals such as nickel, copper, cobalt, iron etc. These compounds are also semi-conductor. For thermistor \(\alpha \) is very high which may be positive or negative. The resistance of thermistors changes very rapidly with change of temperature.
Thermistors are used to detect small temperature change and to measure very low temperature.

]]>The post Law of Radioactive Disintegration appeared first on MyRank.
]]>The spontaneous breaking of a nucleus is known as Radioactive Disintegration. According to Rutherford and Soddy made experimental study of the radioactive decay of various radioactive materials and gave the following the laws:
Radioactive decay is a random and spontaneous process. It is not influenced by external conditions such as temperature, pressure, electric field etc. each decay is an independent event occurs by a chance to take first.
In any radioactive decay, either a \(\alpha \) particle or \(\beta \) particle is emitted by the atom. Emission of both is impossible at a time. Moreover, an atom doesn’t emit more than one \(\alpha \) particle or more then on \(\beta \) particle at a time.
At any instant the rate of decay of radioactive atoms is proportional to the number of atoms present at that instant, i.e.
\(-\frac{dN}{dt}\propto N\Rightarrow \frac{dN}{dt}=-\lambda N\),
It can be proved that, \(N={{N}_{0}}{{e}^{-\lambda t}}\),
This equation shows that number of atoms on taken radioactive element decreases exponentially with time. Theoretically, infinite time is required for radioactivity to disappear completely and this is same for all elements. In terms of mass, \(M={{M}_{0}}{{e}^{-\lambda t}}\)
Where, N = Number of atoms remains un-decayed after time t,
\({{N}_{0}}\) = Number of atoms present initially,
\(M=\) Mass of radioactive nuclei at time t,
\({{M}_{0}}=\) Mass of radioactive nuclei at time t=0,
\({{N}_{0}}-N=\) Number of disintegrated nucleus in time t
\(\frac{dN}{dt}=\) Rate of decay,
\(\lambda \) = Disintegration constant (or) decay constant of the radioactive element.
