Answer:
The constant torque required to stop the disk is 8.6 N-m in clockwise direction .
Explanation:
Let counterclockwise be positive direction and clockwise be negative direction .
Given
Radius of disk , r = 1.33 m
Mass of disc , m = 70.6 kg
Initial angular velocity , 
Final angular velocity , 
Time taken to stop , t = 2.75 min
Let 
be the angular acceleration
We know
=>
=>
Torque required to stop is given by
where moment of inertia , 
=>
Thus the constant torque required to stop the disk is 8.6 N-m in clockwise direction .
Answer:
1) Coal is a natural resource, so is wood, wind energy, soil, salt, fluorite, water, and copper
2) Solar energy, natural gas, and wind energy are all renewable
3) Salt is non - renewable as is synthetic diamonds and plastic
4) I think it would be number
5) Based on their mineral, chemical, and textural composition

Answer:
Part A:
Part B:
Option B (Towards the South)
Explanation:
Part A:
Magnitude if electric field E:
E=Force/charge
Force=2.04×10−14 N
Charge=1.6×10−19 C
Part B:
Option B (Towards the South)
As electron is experiencing the force towards south,it means the direction of the electric field is towards the south because direction of field lines is from positive to negative, so proton is moving towards south it means negative charge is in south to which proton is attracted. So electric field is towards South.
The best and most correct answer among the choices provided by your question is the second choice or letter B.
