A particle executing simple harmonic motion possesses both kinetic energy and potential energy and the total energy of particle executing simple harmonic motion at any point is equal to the sum of kinetic energy and potential energy i.e.Let at any instant, the particle be at P at a distance y from mean position and v be the velocity of particle at P.
Kinetic energy: The kinetic energy of particle executing simple harmonic oscillation at any instant is given byThe velocity of particle at a distance y from the mean position is,Potential energy: The potential energy stored in the particle is eq

Any process in which no heat is allowed to be exchanged with surroundings is called an adiabatic process. Essential conditions for the adiabatic process to take place are: i) System is perfectly insulated from surrounding. ii) The process must be carried out rapidly so that the system hs sufficient time to exchange heat with the surroundings. 

When isobars are straight and when there is no friction, the gradient force is balanced by the Coriolis force and the resultant winds blow parallel to the isobars. These winds are known as the geotrophic winds.

बाज़ार में उपभोक्ताओं की सुरक्षा के लिए नियम एवं विनियमों की आवश्यकता होती है, क्योंकि अकेला उपभोक्ता प्राय: स्वयं को कमजोर स्थिति में पाता है। खरीदी गयी वस्तु या सेवा के बारे में जब भी कोई शिकायत होती है, तो विक्रेता सारा उत्तरदायित्व क्रेता पर डालने का प्रयास करता है।बाज़ार में शोषण कई रूपों में होता है।उधारणार्थ:(i) कभी-कभी व्यापारी अनुचित व्यापार करने लग जाते हैं, जैसे दुकानदार उचित वजन से काम वजन तौलते हैं या व्यापारी उन शुल्कों को जोड़ देते हैं, जिनका वर्णन पहले न किया गया हो या मिलावटी/दोषपूर्ण वस्तुएँ बेची जाती हैं।(ii) उदाहरण के लिए, एक कंपनी ने यह दावा करते हुए की माता के दूध से हमारा

The thin soap film formed between the wire and slider has two free surfaces.Therefore, total length of free surface that touches with slider is 2L = 60cm = 0.60 m.
Because the slider can support 1.5x10–2N weight.

We have,r = radius of the cylinder= radius of hemispherical ends = 14 cmh = height of cylinder = 72 cm∴ Total surface area = curved surface area of the cylinder + surface areas of hemispherical ends= (2rh +2 x 2r2) cm2= 2r (h + 2r) cm2
Now, cost of polishing the surface of the solid at the rate of 5 paise per sq. m

Escape velocity is minimum velocity with which a body must be thrown upward so that it may just escape.Expression for escape velocity:Let a body of mass m be escaped from gravitational field of the earth. During the course of motion, let at any instant body be at a distance r from the centre of the earth.The gravitational force between body and the earth is,                               and work done to raise the body by distance dr is,                                Total work done W in raising the body from the surface of the earth to infinity is,                                          

By KVL along path ACDBVA + 1 (1)(2) - 2  = VB0+1 = VB VB  = 1V

Let x and y represent the number of units produced per week of the products A and B respectively. Let Z be the profit corresponding to this rate of production. ThenZ = 40 x + 35 y ...(1)In order to produce these number of units,total consumption of raw material = 2x + 3yand total labour hours needed = 4x + 3yBut total raw material available = 60 kgand total labour hours available = 96∴  we have,                                             ...(2)∵  it is not possible to produce negative number of units∴ x ≥ 0, y ≥ 0    ...(3)∴ firm’s allocation problem can be put in the following mathematical

Given, three capacitors P,Q and R.Charge acquired by the capacitor when, P is charged to a potential difference V is, Q=CV.i) When P is connected to Q in parallel : total capacitance -C=C1+C2 = 2Ctotal charge on two capacitors=q+0=q=CV∴ potential difference between the plates of P= CV2C=V2ii) When P is connected to R in series :On such a connection, the circuit will not be completed. And hence, the sharing of charges will not take place. So, the potential will remain as V. That is, it remains unchanged.

Commoditisation:It was the transformation of non-commodity (viz. things not bought and sold for money in the market).
Examples:(i) Labour or skills become things that can be bought and sold in the market for wage, fee in terms of money.
(ii)    Sale of kidneys by the poor to cater to rich patients who need kidney transplants.
(iii)    Marriage for fee are arranged by marriage bureau and through websites.
(iv)    There are courses conducted on charge hr teaching cultural and Social skills while in earlier times, these were taught in an automatic way and through interaction of children with

The central metal ion is Co..It coordination number is 6.The oxidation state can be given as:X-6 = -3X= +3Oxidation state is +3.
d-orbital occupation is t2g6  eg0 since oxalate is strong field ligand therefore pairing occur.

સંસાધન એટલે જે વસ્તુ પર માનવી આશ્રિત કે અધારિત હોય, જેનાથી માનવીની જરૂરિયાતો પૂરી થતી હોય અને માનવી પાસે તેનો ઉપયોગ કરવાની શારીરિક કે બૌદ્ધિક ક્ષમતા હોય. અર્થાત્ કોઈ પણ વસ્તુ માનવીની જરૂરિયાતો પૂરી કરવા ઉપયોગમાં લેવાય ત્યારે તે સંસાધન બની જાય છે. સંસાધનોના ઉપયોગો : સંસાધનો માનવીને અનેક રીતે ઉપયોગી છે. માનવજીવનના દરેક તબક્કે સંસાધનો એક યા બીજી રીતે ઉપયોગી બને છે. ખેતપ્રવૃત્તિથી ઔદ્યોગિક પ્રવૃતિ સુધીની તમામ પ્રવૃતિઓ પ્રત્યક્ષ કે પરોક્ષ રીતે કુદરતી સંસાધનો પર આધારિત છે. સંસાધનોના ઉપયોગો નીચે મુજબ છે: 1. સંસાધન – ખોરાક તરીકે : માનવીની ખોરાકની જરૂરિયાત વિવિધ સંસાધનો દ્વારા પૂર્ણ થાય છે. વનસ્પતિજન્
