Computer:- Computer is an electronic device which is capable of performing various operations such as arithmetic and logical operation. It process the given input data and gives out processed data. It can accept millions of instructions and can perform operation with accuracy. Basically, it perform three major operation, take input, process and gives output. Data:-…
3.1 Radio Studios A radio station produces on air programs with one or more live presenters and guests in a studio at the station, playing music and other program segments from various devices, and taking phone calls on the air. When needed, the On-Air studio operator also selects another studio in the building or…
In 1811 Amadeo Avogadro proposed his hypothesis. According to his hypothesis under the similar condition of temperature and pressure equal volume of all gases contain the same number of molecules. Application of Avogadro’s Hypothesis:- i] To establish the relation between molecular weight and vapour density or, Prove that: Molecular Weight = 2 × Vapour…
Molecular Weight is the number which shows how many times a molecule of a substance is heavier than 1/12th part of an atom of C12 isotope. In other words molecular weight is the sum of atomic weight of all atoms present in a molecule of a substance. eg. Mol. wt. of CaCO3 =1×40 + 1×12…
STP or NTP Pressure = 760 mmHg = 1 atm T = 273K = 0°c 100ml = 1000cc = 1 LitreAt STP 1 ml or 1 cc of hydrogen = 0.000089 gm Atomic Weight = Equivalent Weight × Valency In oxide formation method: In Hydrogen Displacement Method: In Chlorine…
According to Dulong and Petit’s Law, the product of atomic weight and specific heat equals to 6.4 (Approx.). This law can be used to calculate exact atomic weight. In this method equivalent weight and specific heat are determined experimentally. Then approx. atomic weight is calculated as:- Approx. Atomic weight × Specific Heat = 6.4…
2.1 Types of Radio Broadcasting Broadly speaking, Broadcasting means electronic transmission of radio and television signals that are intended for general public reception. It is also known as the systematic dissemination of entertainment, information, educational programming and other features for simultaneous reception by a scattered audience with appropriate receiving apparatus. Broadcasts may be audible only,…
1.1 Fundamental of Sound Sound is considered as a physical disturbance in a medium. The sound is actually pressure waves in the air which cause our eardrums to vibrate. For sound to be propagated from one place to another, a medium is required that has elasticity and inertia. By virtue of elastic and inertial forces…
Atomic Weight is the average relative weight per atom of an element according to their abundance considering an atom of C12 isotopes as 12 amu. For Example: Naturally occurring Chlorine contains 75% Cl35 and 25% Cl37, so atomic of Chlorine In other words, atomic weight is the number which show how many times an…
(Present Status of Dalton’s Atomic Theory) Atoms are no longer considered as indivisible particles. Since sub-atomic particles like electron, proton, neutron etc. are present in atoms. Atoms of same element may not be identical in all aspects due to the presence of isotopes. Atoms of different element can also have some similarities. …
I am trying to develop a educational website which may be helpful for school students, college students, teachers, professor & many more………! If you have any queries, then you can contact me.
