PLEASE MARK MY ANSWER AS BRAINLIEST!!!
-> L = [mr2]ω
L = [mv2t2]ω
L = mv2ωt2
τ=δtδL = 2mv2ωt (directly differentiate the eq. given above)
τ∝t
Therefore, straight line passes through ( 0,0 )
-> Centripetal acceleration, property of the motion of a body traversing a circular path. The acceleration is directed radially toward the centre of the circle and has a magnitude equal to the square of the body's speed along the curve divided by the distance from the centre of the circle to the moving body.
