1.	In the equation b=a^(2) cos^(2)((2pi beta gamma)/(alpha)). If the unitsof a, alpha, and beta are m, s^(-1) and (ms^(-1))^(-1). respectively. The unit of b and Y......
Answer» `m and ms^(-2)` `m^(2) and ms^(-2)` `m^(2) and (ms^(-2))` `m and (ms^(-2))^(-1)` Solution :`:.b=a^(2)cos^(2)((2pi BETA gamma)/(alpha))` `:.` Unit of b= unit of`a^(2)` `:.` unit of `(2pi beta gamma)/(alpha)`= unitless `:.` UNITS of `gamma`= unit `(alpha)/(beta) [ :.` unitless] `:.` Units of `gamma=(s^(-1))/((ms^(-1))^(-1))=s^(-1)xxms^(-1)` `:.` Unit of `gamma==(m)/(s^(2))=ms^(-2)`
