Answer:

A dissipates more power.

Explanation:

$P = I^{2} * R$

So, for a given current, the power is directly proportional to the resistance of the resistor.
In this case, as resistor A has twice the resistance of resistor B, A dissipates twice more power than B.

Answer:

we have τ = I * α as the rotational equation of motion

and we also have τ = F * r

so the torque τ = 5* 0.16 Nm = 0.8 Nm

from your plot of θ vs T^2 , calculate the slope of the line

this slope will be angular acceleration α.

Then you get I = τ/α
