It is given that any two different system so you must to take L and T
this answer is right
The Velocity time graph for such an accelerated motion is an inclined straight line passing through the origin as shown in Fig☝️☝️
Acceleration = change in velocity/change in time
Hope it helps you.

Velocity-time graph of an object moving with uniform velocity
The slope of a Velocity–time graph of an object moving in rectilinear motion with uniform velocity is straight line and parallel to x-axis when velocity is taken along y-axis and time is taken along x-axis.
Velocity Time Graph
please follow me
here's the answer dear
Centripetal means towards the center. Even an object moving at a constant speed around a circle won't have a constant velocity. This is because velocity is a vector. ... Centripetal acceleration is measured in meters per second per second (m/s/s) and can be calculated using the equation a = v^2 /r
the velocity time graph shows velocity in ( m/s)

When velocity – time graph is plotted for an object moving with uniform acceleration, the slope of the graph is a straight line.
The slope of the velocity time graph of an object moving with uniform decreasing velocity with uniform acceleration is a downwards straight line. The straight downward slope shows the decreasing velocity with uniform acceleration, i.e. retardation.

classically, an electron can be in any orbit around the nucleus of an atom. then what determines the typical atomic size? why is an atom not, say, thousand times bigger than its typical size? the question had greatly puzzled bohr before he arrived at famous model of the atom that you have learnt in the text. to simulate what he might well have done before discovery, let us play as follows with the basic constants of nature and see if we can get a quantity with the dimensions of length that is roughly equal to the known size of an atom
(a) construct a quantity with the dimensions of length from the fundamental constants e,
, and c. determine its numerical value.
(b) you will find that the length obtained in (a) is many orders of magnitude smaller than the atomic dimensions. further, it involves c. but energies of atoms are mostly in non-relativistic domain where c is not expected to play any role. is what may have suggested bohr to discard c and look for ‘ else’ to get the right atomic size. now, the planck’s constant h had already made its appearance elsewhere. bohr’s great insight lay in recognising that h,
, and e will yield the right atomic size. construct a quantity with the dimension of length from h,
, and e and confirm that its numerical value has indeed the correct order of magnitude
then what ever the emplitude will be multipliy it with 2
