1) If 3x10^-19 J are required to remove an electron from a specific metal's surface, calculate threshold frequency and correspoinding threshold wavelength for the light incident upon the metal ans: frequency = 4.5x10^24 Hz Wavelength = 6.6 x 10^-7 m 2) Explain how photoelectric...

what is the UV catastophe saying? .. that lower wavelength would have infinite energy?? why did they think this way... obviously this isnt true because of conservation of energy.. then planck tried to give a solution to this problem .. and he explained that it gotta do with energy being...

1)Find A and B given that x^3 + 3x + 2i = (x-A)^2 (X-B) as simple as that. But i need help.. :apig: 2) Find all roots of the equation 18x^3 + 3x^2 - 28x + 12=0 if 2 of the roots are equal could u use sum of roots for this question??

hello, how can u differentiate between a : primary standard, secondary standard, primary standard solution, standard solution

1) find the equation of the tangent to the curve xy(x+y)+16=0 at the point on the curve where the gradient is -1 2)the chord AB of a circle of radius r subtends an angle of 2a radians at the centre O. The perimeter of the minor segment AB is K times the perimeter of the triangle OAB. Show...

the equation showing synthesis of ammonia is N2(g) + 3H2(g) <=> 2NH3 (g) delta H =-92kJ/mol in one production cycle, 28x10^-3 Kg of N2 react with 6x10^-3kg of H2. 6.8x10^-3 Kg of NH3 (g) are produced. how much heat is released? show working out please..

im confused over sum types of section 1 umat questions. Some question tells u to infer, (like why this occurs) while others asks to find the fact ( no reasons to state why).eg, look at this question. 1)Botanists studied a rainforest in Nicaragua that had been ravaged by hurrican in 1998...

what is the difference between an equivalence point and an end point? is equivalence point one where first sign of colour change occurs or is it equal moles of H+ and OH- being added together? 4) A mass of 0.665g of sodium carbonate is used to prepare a solution in a 250ml...

this question asks: evaluate importance of monitoring and management in the haber process. i cant think of sum aspects saying it might not be important to monitor and manage.. since its an evaluate question.. can sum1 help.. or is it not necessary to say it..

In a multiple choice test i had recently, it asked for the process to get from ethanol (aq) to ethanol (l) where ethanol (aq) was from the fermentation process. it was a choice between distillation and filtration. I know (probably) sum textbooks say distillation but this process would only...

i wana know if year 11 stuffs gona be in hsc.. things like maximisation, minimisation..absolute values. maths induction i know that its the basics for the understanding of year 12s stuff.. but there are sum tricky maximisation questions or absolute values out there. would there be specific...
