Ram walks along the path shown in figure (bold lines), from A to B. If the distance covered by Ram is d, then the integer closest to `d/3` is

One mole of an ideal gas is taken from a to b along two paths denoted by the solid and the dashed lines as shown In the graph below. If the work done along the solid line path is W_(s) and that along the the dotted line path is w_(d) , then the integer closest to the ratio w_(d)//w_(s) is

A person walks along the path shown in Fig. 3.53. The path from B to C is semicircular and centred at O. If the magnitude of displacment of the person is 2m, distance travelled by him is nearly :

One mole of an ideal gas is taken from a and b along two paths denoted by the solid and the dashed line as shown in the graph below. If the work done along the solid path is w_(s) and that along the dotted path is w_(d) , then the integer closest to the ratio w_(d)//w_(s) is

The variation of velocity of a particle moving along a straight line is illustrated in the following figure. The distance covered by the particle in 4 seconds is :

Acyclist moves from Oto D along path as shown. What is the is the distance moved by him ?
