Answer:
They're going to increase the total resistance as 
Explanation:
If the resistors are in parallel, the potential difference is the same for each resistor. But the total current is the sum of the currents that pass through each of the resistors. Then

Answer:
τ=0.060 N.m
Explanation:
By kinematics:

Solving for α:

where ωo = 600*2*π/60;   ωf = 0;    t=10s

The sum of torque is:
