Solution of triangles - We have studied that a triangle has six parts or six elements viz three sides and three angles. From geometry, we know that when any three elements are given of which necessarily a side is given, the triangle is completely determined i.e, remaining three elements c..

The application of Boolean algebra to electronic devices such as computers, lies in the restriction of the variable to two possible condition 'On and Off' or 'True or False' or numerically '1 or 0'. The electric circuits carry out the Boolean logic. In practice, electronic engineers use t..

Limitations of Linear Programming - Linear programming is applicable only to problems where the constraints and objective function are linear i.e., where they can be expressed as equations which represent straight lines. In real life situations, when constraints or objective functions are not linea..

The circular functions are functions of an angle. They are important in the study of triangles and modeling periodic phenomena, among many other applications. Trigonometric functions are commonly defined as ratios of two sides of a right triangle containing the angle, and can equivalently be ..

Different forms of numbers Scientific notation, square roots, exponents, radicals, absolute value, factorial, logarithms Properties of numbers Estimation of solutions Sequences and series Proportionality/direct variation, exponential/fractional expressions Patterns, rela..

The frequency ( n ) of emitted light is related to the energy difference of two levels ( D E) as E = 214.68 kJ mol - 1 , h = 39.79 x 10 - 1 4 kJ mol - 1 = 5.39 x 10 1 4 s - 1 8. The wavelength of first spectral line in the Balmer series is 6561 units. Calculate the wavel..

Given: Wattage = 100 W Voltage = 220V Since the electrolytic cell is connected in series, the same current flows through the cell. Time, t = 5h = 5 x 60 x 60s = 18000s So, Quantity of electricity passed, Q = I x t coulombs = 0.454 A x 18000 s = 8172 C For the reduction of Cu 2 + to C..

Characteristics of Electrochemical Series - 1) Reactive metals are placed on top (e.g., Li) and they have a great tendency to get oxidized. Non-reactive metals like Ag and Au. 2) Any metal above hydrogen can displace it from dilute acids. Example: Any metal which is above another can disp..

The higher the metal in the series, the more reactive it is i.e., its reaction is fast and more exothermic. This also implies that the reverse reaction becomes more difficult i.e., the more reactive a metal, the more difficult it is to extract from its ore. The metal is also more suscepti..
