Why does iron(or other magnetic substance) loses their magnetism when heated?

Iron becomes non magnetic when heated above 770°C. The temperature at which the substance loses its magnetism is called Curie point. High temperature disturbs the process of magnetism i.e, when the iron is heated,the atoms of the iron are vibrated with higher kinetic energy and loses the ability to be magnetized. Higher K.E.(random motion ofContinue reading “Why does iron(or other magnetic substance) loses their magnetism when heated?”

Empty space are kept in medical tablets, why?

1)Tese empty space prevent medicines from breaking down and also from external sock and vibration 2)Empty space are used to print the information including manufacture and expiry date. 3)For packets consisting of only one pill,these empty space is also maintained to increase the print area 4)When medicines are taken from place to place, they areContinue reading “Empty space are kept in medical tablets, why?”

Weight of a body is found less at the top of a mountain than at the bottom of it, why?

Ans: As we know that: weight(w)= mass(m)×accelearation due to gravity(g) The value of ‘g’ is more at the bottom of a mountain due to less radius and less at the top of the mountain due to more radius (•.• g is inversly proportional to square of the radius) . Therefore, the weight of an objectContinue reading “Weight of a body is found less at the top of a mountain than at the bottom of it, why?”

What is uric acid? What are the preventive measures of uric acid?

Uric acid is a compound of carbon, nitrogen, oxygen and hydrogen with the formula C5H4N4O3. It forms ions and salts known as urates and acid urates, such as ammonium acid urate. Uric acid is a product of metabolic breakdown of purine nucleotides and it it a normal component of urine. In human blood plasma, theContinue reading “What is uric acid?

The offspring produced by asexual and sexual reproduction process are dissimilar. why?

In asexual reproduction, crossing over does not take place and gamates are not produced. So, offspring produced by asexual reproduction are genetically identical to the parent. But in case of sexual reproduction,crossing over takes place during the formation of gamets. So variation occurs in the offspring

पानीमा लठ्ठी डुबाउँदा बाङ्गो र छोटो देखिन्छ किन?

पानीमा लठ्ठी डुबाउँदा बाङ्गो र छोटो देखिन्छ। लठ्ठीको तल्लो भागबाट आएका प्रकाशका किरणहरु जब पानीबाट हावामा प्रबेश गर्छन,चित्र(२)मा देखाएजस्तै गरि माध्यम(पानीबाट हावा) परिवर्तन गर्दा तिनीहरुको गति परिवर्तन हुन्छ र नर्मलबाट टाढा बाङ्गिन्छन । तसर्थ डुबेको भाग माथी उठेको जस्तो देखिन्छ र भाँचिएको जस्तो देखिन्छ। चित्र नं.(१) चित्र नं.(२)

How to measure blood pressure?

Blood pressure is measured by using sphygmomanometer Step2 An inflatable cuff is placed around the upper arm and inflated until all blood flow,in or out of the arm stops. The blood flow is monitored using a stethoscope. Step2 After inflation,there is no sound but as air escapes from the cuff, the pressure decreases until itContinue reading “How to measure blood pressure?”
