What is electricity? |
| Answer» CITY is the flow of electrical power or charge. It is a secondary energy SOURCE which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. The energy sources we use to make ELECTRICITY can be renewable or non-renewable, but electricity itself is NEITHER renewable or non-renewable. | |

Answer» कूलॉम-नियम (COULOMB's law) विद्युत आवेशों के बीच लगने वाले स्थिरविद्युत बल के बारे में एक नियम है जिसे कूलम्ब नामक फ्रांसीसी वैज्ञानिक ने १७८० के दशक में प्रतिपादित किया था। यह नियम विद्युतचुम्बकत्व के सिद्धान्त के विकास के लिये आधार का काम किया। यह नियम अदिश रूप में या सदिश रूप में व्यक्त किया जा सकता है। अदिश रूप में यह नियम निम्नलिखित रूप में है-दो बिन्दु आवेशों के बीच लगने वाला स्थिरविद्युत बल का मान उन दोनों आवेशों के गुणनफल के समानुपाती होता है तथा उन आवेशों के बीच की दूरी के वर्ग के व्युत्क्रमानुपाती होता है।इस नियम को अदिश रूप में निम्नलिखित प्रकार से लिख सकते हैं-{\displaystyle F=k_{e}{\frac {q_{1}q_{2}}{R^{2}}},}{\displaystyle F=k_{e}{\frac {q_{1}q_{2}}{r^{2}}},}जहाँ ke कूलॉम्ब नियतांक है जिसका मान ke ≈ 9,00,00,00,000 N⋅m2⋅C−2 होता है।[1] q1 और q2 दोनों आवेशों के चिह्नसहित मान हैं, और r दोनों आवेशों के बीच की दूरी है। जब दोनों आवेश विपरीत चिह्न के होते हैं तो उनके बीच आकर्षण होता है जबकि दोनों आवेश समान होने पर प्रतिकर्षण होता है। |

How does the density of water changes when :(a) it is heated from 0°C to 4°C. (b) it is heated from 4°C to 10°C ? |
|
Answer» a). increasesb). decreasesExplanation:When water is heated from 0 0C, its volume decreases because its DENSITY increases and you can see this effect upto 4 0C. Because the density of ice is maximum at 4 0C. Afterwards as the density decreases the volume increases. The main reason for this is HYDROGEN bond in ice GETS CLEAVED due to the melting of ice |

Force of attraction between two point electric charges placed at a distance d in a medium is F. What distance apart should these be kept in the same medium, so that force between them becomes 3F ? |
|
Answer» distance between the charges should be d/√3Explanation:MAGNITUDE of FORCE F = k q₁q₂/d²Since same charges are in same mediumF ∝ 1/d²∴ F₁/F₂ = (d₂/d₁)²∴ d₂/d₁ = √(F₁/F₂) = 1/√3 d₂ = d/√3 ∴ distance between the charges should be 1/√3 times the INITIAL SAPERATION. |
