In the given graph between two physical quantities 'a' and 'b' as shown in the figure 'b' is along x-axis while 'a' is along y-axis. The plot describes the motion of a particle in a straight line then

Options

A. Quantity 'b' may represent time.
B. Quantity 'a' can be velocity if motion is uniform.
C. Quantity a should be displacement if motion in uniform
D. Quantity 'a' should be velocity if motion is uniformly accelerated.

Answer

a,c,d

Explanation

Here if time .t. is represent along x-axis then the graph represent displacement time graph for uniform motion in which the displacement goes on increasing uniformly with time.
Also .a. can act as the acceleration for uniformly accelerated motion. Thus (a),(c),(d) can be taken to be correct (c) and (d) under different condition as stated above.
