Report | Achu asks : A middle aged woman wears eye glasses with power of -5.5D for myopia. Her doctor prescribed a correction of +1.5D in the near vision portion of her bifocals.This is measured relative to the main part of the lens. (1)What is the focal length of her distant viewing portion of the lens? (2)What is the focal length of the near viewing portion of the lens? |
Report | Harminder singh asks : what is the value of sum of n terms of the series whose nth term is(2sinA) raised to power n where n belongs to +ve integers. help yar, I am really confused for it. I just need it to solve a big problem of my life |
Report | Bheemaiah ch asks : therr are 12 buses in a power system and it has 3 voltage control buses then what is the size of jocobian matrix |
Report | B ramesh babu asks : Hai..........Can any one tell...........Why the Voltage ratings in power system are in Multiples of 11s |
Report | Joydeep roy asks : here ar a few questions . 1) a monoatomic ideal gas ,initially at temp.T1 ,IS ENCLOSED IN A CYLINDER FITTED WITH A FRICTIONLESS piston. The gas is allowed to expand adiabatically to a temperature T2 by releasing the piston suddenly. If L1 and L2 are the lengths of the gas column before and after expansion respectively, then T1/T2 is given by (a) [L1/L2]^2/3 (b) [L1/L2] (c) [L2/L1] {^ Here means to the power of } (d) [L2/L1]^2/3 2)a thin brass sheet at 10degree C and a thin steel sheet at 20degree C have the same surface area.The common temperature at whch both would have the same area is (coeff of linear exp. for brass & steel are 19*10^-6 /deg C & 11*10^-6/deg C RESP.) a)-3.75 degC (B)-2.75 degC (C) 2.75 degC (D) 3.75 degC SIR PLS SOLVE THESE QUESTIONS WITH SOME TIPS AND TRICKS ANS: (1)d (2)a |
