Explain diffraction of light from Snell's law |
|
Answer» Explanation: SNELL's Law, which can be stated as. nA Sinθ A = nB Sinθ B. predicts how the ray will change direction as it PASSES from ONE medium into another, or as it is reflected from the interface between two media. The ANGLES in this equation are referenced to a SURFACE normal, as is illustrated below. |

Answer» बहुत ही अच्छा सवाल है। भौतिकी एक प्रायोगिक विज्ञान है। इसमें हर कदम पर मापन की आवश्यकता होती है। भिन्न-भिन्न भौतिक राशियों के मापन के लिए भिन्न-भिन्न मापक यंत्र का उपयोग किया जाता है। मापन की यथार्थता मापन यत्रों की विभेदन(RESOLUTION) या सीमा(Limit) के अतिरिक्त अन्य बातों पर भी निर्भर करती है। यही कारण है कि मापित मान (MEASURED VALUE)या प्रेक्षित मान (Observed Value) वास्तविक मान से कुछ भिन्न होता है। इसलिए हम मापन के लिए दो पदों का उपयोग करते हैं। यथार्थता (ACCURACY) :- जब किसी भौतिक राशि का मापित मान उसके वास्तविक मान के अधिक निकट होता है तो मापन की यथार्थता अधिक होती है। परिशुद्धता (Precision):- जब भौतिक राशि अधिक विभेदन या सीमा तक मापी जाती है तो मापन की परिशुद्धता अधिक होती है। मापन की परिशुद्धता मापन यंत्र के अल्पत्मांक (Leastcount)पर निर्भर करती है। अल्पत्मांक कम होने पर परिशुद्धता अधिक होती है। आइए इसे एक उदाहरण से समझने की कोशिश करते हैं। जैसे मान लो किसी गोले के व्यास का वास्तविक मान 1.635 सेंटीमीटर है। 0.01 सेंटीमीटर अल्पतमांक वाले यंत्र A से मापे जाने पर इस का मान 1.62 सेंटीमीटर तथा 0.001 सेंटीमीटर अल्पतमांक वाले दूसरे यंत्र B से मापे जाने पर यही मान 1.591 सेंटीमीटर प्राप्त होता है। तो हम यह तुलना कर सकते हैं कि यंत्र A के द्वारा मापित मान में अधिक यथार्थता है क्योंकि यह वास्तविक मान के अधिक निकट है। और यन्त्र B द्वारा मापित मान में अधिक परिशुद्धता हैं क्योंकि यन्त्र B का अल्पत्मांक यन्त्र A की तुलना में कम है। |

Gunpowder contains 75%nitre and 10%sulphur find the amount of gunpowder which carries 9kg nitre. What amount of gunpowder would contain 2.5kgdon't spam ✖✖❌❌full explanation |
|
Answer» Percentage of nitre in GUNPOWDER = 75% Amount of nitre in gunpowder = 9 KG Let US CONSIDER the amount of gunpowder be ‘X’ kg So, by calculating (x/100) × 75 = 9 By cross multiplying x/100 = 9/75 x = (9×100)/75 = 12kg Percentage of sulphur in gunpowder = 10% Amount of sulphur in gunpowder = 2.3 kg Let us consider amount of gunpowder be ‘x’ kg So, by calculating (x/100) × 10 = 2.3 By cross multiplying x/100 = 2.3/10 x = (2.3×100)/10 = 23kg ∴ The amount of gunpowder in nitre is 12kg The amount of gunpowder in sulphur is 23kg please Mark me as brainliest please |

1) what is ideal machine ?2) what is heat capacity ? |
|
Answer» Answer: 1) An ideal machine is a machine in which energy given as the output is equal to the input energy. The principle of an ideal machine is to convert all the given energy into a useful energy. ... Some of the energy given to the machine is converted to some energy that is not required like heat and sound. 2.Heat CAPACITY is the ratio of the amount of heat energy transferred to an OBJECT to the resulting increase in its temperature. Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one MOLE of a pure substance by one degree K. HOPE you understood |

What is dimensional analysis and how is it used to verify the answer to an equation? |
|
Answer» Answer: Dimensional ANALYSIS (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by ONE without changing its value. It is a useful technique. and In engineering and science, dimensional analysis is the analysis of the relationships between different physical QUANTITIES by identifying their base quantities (such as length, mass, time, and electric charge) and units of measure (such as miles vs. kilometres, or pounds vs. kilograms) and tracking these dimensions Dimensional Analysis is a WAY chemists and other scientists convert units of measurement. We can convert any unit to ANOTHER unit of the same dimension. With a known conversion factor, it is sometimes possible to convert to a new dimension |
