Sheela walks from A to B which is 2 km, away turns right at 90 ∘ and walks for 3 km, to point C turns right at 90 ∘ and walks to D which is 8 km, away, turns 90 ∘ right and goes 3 km, to point K Then once again the she turns right 90 ∘ and walks 4 km to pint F how far is it from A to F?

Sandhya walks straight from point A to B which is 2 kms away. She turns left at 90° and walks 8 kms to C, where she turns left 90 ∘ and walks 5 kms to D. At D she turns left 90 ∘ and walks for 8 kms to E. How far is she from A to E?

The root means square (R.M.S.) Speed V of the molecules of an ideal gas is given by the expressions, v = √ (3RT/M) and v = √ (3KT/m) where R is universal gas constant, T is the absolute (Kelvin) temperature M is the molar mass, K is Boltzman's constant and M is the molecular mass.

A man travels 7 kms towards East, then he turns left and travels 8 kms, again he turns left and travels 10 kms. Finally, he turns left and travels 2 kms. In which direction is he from his starting point?

A man went 1 0 kms towards South, then turned East and covered 1 0 kms and turned to the right. Again after 1 0 kms he turned to left and covered 1 0 kms to reach the destination. How far and in which direction is he to his starting point?
