ANSWER
When a solution of acetic acid in water is shaken with charcoal, a part of the acid is adsorbed by the charcoal and the concentration of the acid decreases in the solution. Similarly, the litmus solution when shaken with charcoal becomes colourless.

बहुउद्देश्यीय कम्पनी एक बड़ी कंपनी है जो अपने उत्पादक और व्यावसायिक गतिविधियों को एक से अधिक देशों में करती है।
इसे एक स्थानान्तरण निगम भी कहा जाता है क्योंकि इसका संचालन उस देश की सीमाओं से परे होता है जिसमें यह शुरू किया गया था।
उदाहरण: भारत में काम करने वाले बहुराष्ट्रीय कंपनियां जॉनसन एंड जॉनसन और कोका-कोला हैं और भारतीय बहुराष्ट्रीय कंपनियों में टाटा स्टील और रिलायंस इंडस्ट्रीज शामिल हैं।

When an inductor and capacitor are connected together , energy flows from capacitor to inductor and then back to capacitor. This process continues forever in the absence of resistance in a cyclic oscillatory manner. Since there is no resistance, energy can not dissipate via inductor and capacitor and the whole energy of the system continues to swing back and forth between inductor and capacitor.
Let a capacitor which is initially charged as Q₀ and an inductor with initial current 0 are connected together.
So the initial energy of the system,
U₀ = energy stored in the capacitor + energy stored in the inductor
= Q₀²/2C + 0
= Q₀²/2C
when the switch is closed current starts flowing in the circuit and capacitor starts discharging, this current flows in the circuit until the capacitor is discharged completely. Let the final maximum current be I₀.
So final energy stored in the system now
Uₙ = energy stored in the capacitor + energy stored in the inductor
= 0 + LI₀²/2
= LI₀²/2
This current continues to flow in the circuit even after the capacitor is discharged totally because the inductor opposes the change in current. So this current now starts charging the capacitor until it is fully charged in the reverse polarity. This cycle of energy flow continues forever.
At any point the energy stored in the system will be the sum of energy stored in the capacitor and inductor.
U = Q²/2C + LI²/2
Since there is no resistance in the circuit energy dissipation does not takes place and the total energy of the system always remains constant.
Hence ,
U = Q²/2C + LI²/2 = LI₀²/2 = Q₀²/2C

A pure inductor of 25mh is connected to a source of 220v.Find inductive reactance and rms current in the circuit, frequency of source is 50Hz. |
|
Inductance of Inductor, L = 25 m H = 2 x 3.14 x 50 x 25 x 10-3 = 7.85 ?
|
Inductive reactance , XL = 2? f L

Transparent medium is denser medium as compared yo air bubble,as we know whenever light travels from a denser medium to rared medium it bends aways from normal,hence air bubble inside a transparent medim behaves like a diverging lens as it diverges the rays(moves away from normal).

. विज्ञान न की अंगूठा टेक शासन
- इस सिद्धांत के अनुसार निर्णय तत्वों के आधार तथ्यों पर आधारित होने चाहिए ना कि अंगूठा टेक नियमों के आधार पर संगठन में किए जाने वाले प्रत्येक कार्य वैज्ञानिक जांच के आधार पर होना चाहिए ना कि अंतदृष्टि व निजी विचार पर l
2. सहयोग न कि टकराव
- इस सिद्धांत के अनुसार प्रबंध एवं श्रमिकों में विश्वास एवं समझदारी होनी चाहिए l उन्हें एक दूसरे के प्रति सकारात्मक सोच विकसित करनी चाहिए जिससे वह एक टीम के रूप में कार्य कर सकें l
3. मानसिक क्रांति
- इसके द्वारा श्रमिकों व प्रबंधक को को एक दूसरे के प्रति सोच को बदलने पर जोर दिया गया है l जिससे संगठन में परस्पर विश्वास की भावना उत्पन्न हो सके तथा उत्पादन को बढ़ाया जा सके l दोनों पक्षों के लाभ के बंटवारे की अपेक्षा लाभ में वृद्धि की बात सोचनी चाहिए l
4. सहयोग ना की व्यक्तिवाद
- सिद्धांत मधुरता ना कि विवाद का संशोधित रूप है lइसके अनुसार संगठन में श्रमिकों एवं प्रबंधकों के बीच सहयोग होना चाहिए जिससे कार्य को सरलता से किया जा सके l
5. अधिकतम कार्य क्षमता एवं श्रमिकों का विकास
- टेलर के अनुसार श्रमिकों का चयन कार्य क्षमता के अनुसार कार्य एवं योग्यता को ध्यान में रखकर किया जाना चाहिए तथा उनकी कार्य क्षमता एवं कुशलता बढ़ाने हेतु उन्हें उचित प्रशिक्षण दिया जाना चाहिए इससे कंपनी एवं श्रमिकों की खुशhali बढ़ेगी तथा kushal shramik ke sath सामूहिक उद्देश्य की प्राप्ति में सरलता होगी l

The most stable conformation of a protein at a given temperature and the pH is known as its native state.
• The loss of biological activity of proteins when a protein in its native form, is subjected to physical change like change in temperature or chemical change like change in pH, is called denaturation of protein.
• For example: (i) Coagulation of egg white on boiling, (ii) curdling of milk which is caused due to the formation of lactic acid by the lactobacillus bacteria present in milk.
