The acidic urine becomes alkaline on standing due to the decomposition of urea to …….. 

Given :  Mass of urea = 5.6 g  To find :  The number of moles and molecules of urea  Formulae :  i. Number of moles = \(\frac{Mass\,of\,a\,substance}{Molar\,mass\,of\,a\,substance}\)  ii. Number of molecules = Number of moles × Avogadro’s constant Mass...

Correct option is: (B) \(2v_e\) Escape Velocity \(v_e = \sqrt {2gRe}\) \(\frac{V_{e1}}{V_{e2}} \propto \sqrt \frac{4R_1}{R_1}\) \(V_{escape \ 2} = 2 \ V_{escape \ 1}\)
