Answer / o.v.r.reddy

MULTI EXTRACTIONS WITH COUNTER CURRENT WAY WITH SMALL
VOLUME OF SOLVENT IS BEST OR CONTINUOS EXTRACTION IN TOWER
WITH CONTACTING OF SOLUTE AND SOLVENT PHASES OPPOSITELY
UNDER SLOW STIRRING DEPENDING UPON SP.GRAVITY OF RSFITE AND

Answer / mohan

several small volume exractions are quiet best than the
single exraction..coz thr may be a chance for getting the
undesired product,i mean we dnt get the desired
quality..and also the feed must not be fully extracted in
case of single exraction,moreover it takes much time to
extract the feed..but in multi extractions with small
volume fullfill the drawback from the single extraction..it
takes less time to extract the feed..

Question 61 – A biochemical trolley of mass 15 kg is towing a trailer of mass 5 kg along a straight horizontal pathway. The trailer and the trolley are connected by a light inextensible tow-bar. The engine of the trolley exerts a driving force of magnitude 100 N. The trailer and the trolley experience resistances of magnitude 10 N and 30 N respectively. (a) Form 2 equations with unknowns T and a, that represents the equilibrium for the 2 systems of the trolley and trailer. (b) Solve the simultaneous equations from the 2 equations that are obtained in part (a) of this question. T is the tension of the tow-bar and a is the acceleration.

Question 104 - In photoelectrical effect analysis of quantum chemistry, let E = kinetic energy of electron, p = intensity of UV light, f = frequency of UV light. According to Classical Theory, E = c for all values of f, E = mp. According to Quantum Theory, E = c for all values of p, E = mf + c. In a graph, m and c are constants where m is slope and c is y intercept. If m = 2 and c = 3 with similar value of E : (a) find the value of p according to Classical Theory; (b) find the value of f according to Quantum Theory.
