Q2. Write the principle and application of the following techniques-(i) Chromatography (ii) Sublimation(iii) Separation |
|
Answer» Answer: 1. the action of separating or being SEPARATED; a situation or period of being apart अलगाव, पार्थक्य (अलग करने या होने की क्रिया); अलगाव की स्थिति या अवधि 2. an agreement where a couple decide not to live TOGETHER any more पति-पत्नी में अब साथ-साथ न रहने का समझौता Sublimation is the transition of a substance directly from the solid to the GAS state, without passing through the liquid state. Chromatography is a laboratory technique for the separation of a mixture. The mixture is DISSOLVED in a fluid (gas, solvent, water, ...) CALLED the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which is fixed a material called the stationary phase. |

The acceleration of a moving vehicle is 7m/s^2 what does it mean? |
|
Answer» As stated in other answers, the ACCELERATION is the rate of change of the VELOCITY. So 5 m/s^2 is a change in velocity of 5 m/s every second. As NUMERICAL examples: If you started from rest, then after one second you would have a velocity of 5 m/s. After an additional second you would have a velocity of 10 m/s, etc. If you started at 2 m/s, then after one second you would have a velocity of 7 m/s. After an additional second you would have a velocity of 12 m/s. You don’t have to do whole seconds. If you have just one tenth of a second (0.1 s) then the velocity would INCREASE by 0.5 m/s.

Define ohm s law Answer the following questions |
|
Answer» Answer: Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance,[1] one arrives at the usual mathematical EQUATION that describes this relationship:[2] {\displaystyle I={\frac {V}{R}},}I={\frac {V}{R}}, where I is the current through the conductor in units of AMPERES, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.[3] Ohm's law is an empirical relation which accurately describes the conductivity of the vast majority of electrically conductive materials over many orders of magnitude of current. However some materials do not OBEY Ohm's law, these are called non-ohmic. The law was named after the German physicist Georg Ohm, who, in a treatise published in 1827, described MEASUREMENTS of applied voltage and current through simple electrical circuits containing various lengths of wire. Ohm explained his experimental results by a SLIGHTLY more complex equation than the modern form above (see § History below). In physics, the term Ohm's law is also used to refer to various generalizations of the law; for example the vector form of the law used in electromagnetics and material science.
