Answer:
0.406 rad/s2
Explanation:
We can use the following equation of motion to calculate the angular acceleration α in term of initial angular speed ω = 2.1 rad/s, time t = 5.41 and angles covered θ = 17.3 rad

A)5524J,
B) 29.2Nm
Explanation:
This question can be treated using work- energy theorem
Work= change in Kinectic energy
W= Δ KE
Work= difference between the final Kinectic energy and intial Kinectic energy.
We know that
Kinectic energy= 1/2 mv^2 .............eqn(1)
This can be written in term of angular velocity, as
KE= 1/2 I
Answer: 0.258
Explanation:
The resistance 
of a wire is calculated by the following formula:
(1)
Where:
is the resistivity of the material the wire is made of. For aluminium is 
and for copper is 
is the length of the wire, which in the case of aluminium is 
, and in the case of copper is 
is the transversal area of the wire. In this case is a circumference for both wires, so we will use the formula of the area of the circumference:
(2) Where 
is the diameter of the circumference.
For aluminium wire the diameter is 
and for copper is 
So, in this problem we have two transversal areas:
<u>For aluminium:</u>
(3)
<u>For copper:</u>
(4)
Now we have to calculate the resistance for each wire:
<u>Aluminium wire:</u>
(5)
(6) Resistance of aluminium wire
<u>Copper wire:</u>
(6)
(7) Resistance of copper wire
At this point we are able to calculate the ratio of the resistance of both wires:
(8)
(9)
Finally:
This is the ratio
