Answer:
The final angular velocity is
Explanation:
From the question we are told that
The mass of the first disk is m
The radius of the first disk is r
The mass of second disk is M
The radius of second disk is R
The speed of rotation is w
The moment of inertia of second disk is
Since the first disk is at rest initially
The initial angular momentum would be due to the second disk and this is mathematically represented as
Now when the first disk is then dropped the angular momentum of the whole system now becomes
This above is because the formula for moment of inertia is the same for every disk
According to the law conservation of angular momentum
=>
Answer:
E(0.1m)=-16.53.10^6 V.m
E(0.465m)=-3.55.10^6 V.m
E(1.3m)=-1.27^6 V.m
Explanation:
You can find the field using Gauss's Law:
the surface S is an "infinite long" cylinderr of radio r.
E(r)=
λ=-92.0 μC/m, ε=8.85.10^-12
E(0.1m)=-16.53.10^6 V.m
E(0.465m)=-3.55.10^6 V.m
E(1.3m)=-1.27^6 V.m
The series circuit is the one in which the current flowing through each bulb will be the same as the current at point x.
<h3>What is a series circuit?</h3>
When bulbs are connected in series, the bulbs are connected in an end to end manner. The same current flows through all the bulbs when they are connected in series.
As such, the series circuit is the one in which the current flowing through each bulb will be the same as the current at point x.
