Question is at critical position, at this instant linear velocity vc and angular velocity wc given in the question (not zero).

what theory is applied when this critical position?
Is centre of mass's resultant velocity is zero? ( Vc=Rwc​ )

R radius of circular disk with mass m with initial velocity v and an angular velocity w comes into contact with the ground as shown in the figure. Friction is not negligible, so both the velocity and...

a=F/m ( use F=ma in the direction to center of earth)
=(mg)/m
=g( gravitational acceleration at that place)

one oscillation time is 2.4 s
so error per single oscillation is ±0.1/48*2.4=±0.0005

I measure 20 oscillations time is 48 seconds. If the least count of that clock is 0.1 second.
What is the error for one(single) oscillation time?

Is luminous intensity also basic quanties?

Good question, please try to answer anyone

How some watches needle emit green light when it in dark area?

use s=ut+1/2at^2 ( downwards)
s=+80
u=-30
a=10
...
t>0 so u can get t=8sec

How Lenz's law follows from the Principle of the Conservation of Energy?

initial velocity =498
final velocity =0
distance=0.66
