Answer:
1000 Nm
2000 Nm
1.00007 seconds
Explanation:
I = Moment of inertia = 5 kgm²
= Angular acceleration
= Final angular velocity
= Initial angular velocity
t = Time taken
Torque is given by
The torque of the disc would be 1000 Nm
If 
The torque of the disc would be 2000 Nm
From equation of rotational motion
It would take 1.00007 seconds to reach 3820 rpm

Answer:
From smallest ratio to the largest ratio:
Coasting Universe - Critical Universe - Recollapsing Universe(From left to right)
Explanation:
The coasting universe is one that expands at a constant rate given by the Hubble constant throughout all of cosmic time. It has a ratio of actual density to critical density that is less than 1
The critical universe is one that is at balance with no expansion .I.e. the actual density and the critical density are equal, which makes the ratio of actual density to critical density to be equal to 1
Recollapsing Universe: The expansion of the universe reverses in the future and the universe eventually recollapses. The recollapsing universe has the ratio of the actual density to the critical density to be greater than 1
