Common salt conducts electricity only in molten state.Why? |
|
Answer» Ok thanxx Why ionic compound breakdown in water but they have high electrostatic force? Ok thanxx to all three of you and special thanxx for someone...?? Because in molten state salt contains freeions Common salts are actually ionic compounds formed by positive and negatively charged ions. they Associate into positive and negative ions only in water.._ve end of H2O molecule attracts the +ve end of the salt and vice versa..Thus ions becomes free and are available for the conduction of electric current.. Because nacl break into na+ and cl- ions which help to conduct electricity? Because then breakdown with ions or they have free ions in molten state Any one..! |

Why are rainbows semi circular? |
|
Answer» Bcoz when a raindrop bends light it exits the raindrop at an angle 40 degrees away from the angle it entered the raindrop and forms full circular rainbow,But if the sun is very low in the sky, either just before sunset or just after sunrise, we can see a half circle. The higher the sun is in the sky, the less we see of the rainbow Just rainbow also made from many droplets and droplests behave like a prism Rainbows are actually circular but we cannot see it from the earth. full round rainbow can be seen from an aeroplane Refraction angle is alway low...see in the prism... Semi - circular nahi hota asal ma rainbow circular hota ha . kabhi as man sa dakhna Hey ....Mera nam ka first nd last letter bolo I was thinking about this q. just few mins ago |

Why ammeter is connected is not connected in parallel |
|
Answer» Ammeter measure current flowing in a circuit.it has very low resistance. To ensure correct measurements of current in circuit. If it is connected in // across loads then all current will choose lower resistive path I.e ammeter that cause damage to circuit. ammeter is needed to determine the total current flowing through the circuit. if it is connected in parallel then all the current wont flow through it and it cant give actual current reading.. so ammeter is connected always in series.a voltmeter is used to measure the potential diffrence betn two points which may be the two ends of a battery. so the connection of the voltmeter\'s two terminals should be touching the two ends of the battery or any resistance. in order to do so the voltmeter is always connected to the circuit in parallel.. Becoz. In parallel series all appliances experience same p. D. And ammeter measures elctiric current. So I is necessary. |

why does sky appears blue |
|
Answer» Sky appears blue because of the scattering of blue or violet light in the atmosphere by fine particles like tiny droplets, dust,smoke etc. Blue scater most because it has shorter wavelength. Because of scattering of light and atmospheric refraction Because blue colour has more wavelength than violet and indigo. Also our eyes are more sensitive to blue colour than violet and indigo and hence we see sky blue. Coz,blue color of sunlight scattered much more strongly than the red colour by the particle in atmosphere due to its shorter wavelength Bcoz blue light scattered more in the comperision of other 6 colors Because small particles present in space scatter only blue colour o Blue colour is scattered by atmospheric particles and this colour enters our eyes so sky appears blue....... It appears due to the atmospheric refraction Sky appears blue because blue light scatters the most |
