A. Angular momentum is always conserved would be the correct answer.
This is because like linear momentum (mvmv), angular momentum (r×mvr×mv) is a conserved quantity, where rr is the vector from the center of rotation. For a skater holding a static pose, for each particle making up her body, the contribution in magnitude to the total angular momentum is given by mirivimirivi. Thus bringing in her arms reduces riri for those particles. In order to conserve angular momentum, there is then an increase in the angular velocity.
hope this helps!

Answer:
The minimum uncertainty in the energy state of an atom is 
Explanation:
Given that,
Time t = 10 s
We need to calculate the minimum uncertainty in the energy state
Using Hisen burg of uncertainty principle equation
Where, E = energy
t = time
Put the value into the formula
Hence, The minimum uncertainty in the energy state of an atom is
