    Write an algorithm, using pseudocode or a flowchart, which  inputs a whole number (which is > 0)  calculates the number of digits in the number  outputs the number of digits and the original number (E.g. 147 would give an output of 3, 147)???

    1st join the original point with rotated point( repeat it for next point too) 2nd draw perpendicular bisector of both joint line. 3rd extend the bisector and mark the point where two bisector intersect.(that point is the point of rotation) 4th to find angle of rotation join the original point...

    oh but why ??according to me..if we rinse it with tap water and then distilled water some of water would get remained in flask which would be affecting concentration of alkali.!! anyway would be consulting with my sir.

    for q13 it would (C) bcuz 1mole --------------254g iodine xmole---------------2.54g iodine crossmultiply and u would get 0.01 moles and concentration is provided earlier therefore place in equation i.e C=N/V and get an answer of 0.04mol/dm3 for 19 my guess is (A) bcuz mg is higher...

    first answer is (A) bcuz to re use first is to wash with distilled water than with the solution to be filled with.!! and my guess for next is (C) bcuz this reaction is only possible when hydrogen is removed from carbon therefore four hydrogen would be removed for 4 chlorine so now the formula...

    FRHR is actually for INDUCED current i.e created by cutting of magnetic flux through motion:- used in ac generator b/c based on same theory ..,while FLHR is for ELECTRIC current produced by any source and interaction with magnetic flux to produce motion somehow:- therefore this rule is...

    •The aim of a feasibility study is to see if it is possible to devise a system that can be implemented and that will work at a reasonable cost. •The study ends when a decision whether or not to proceed with the new system has been made. •The results of the study are usually presented as a...

    Water purification is carried out with three simple steps :- 1) Filtration -to remove insoluble particles. 2)Chlorination-to kill bacteria. 3)Carbon treatment- to remove smell. :)

    I could not understand i have took the area of 1/4 sphere and 1/2cylinder , but havent took area of circle bcuz that circle is already included in cylinder!!! o_O:p

    Algorithms!!!

    they are not important ,it is good to write bcuz it would help u to easily refer the previous step if needed.!!!

    in 1st part simply connect three bulbs in parallel b) use the formula P=VI now therefore 30/240 = 0.125 A c) now just multiply by three to get current of three bulbs => 3(0.125) => 0.38 A
