How does the Theory of Uncertainty help to disprove the Newtonian idea of determinism? (Select all that apply)

a. Quantum theory established that the initial velocity and position cannot be known because you cannot simultaneously measure both the position and velocity

b. It helped model the gravitational effect in the fall of an apple from a tree.

c. Heisenbeng developed it based on his observations in which one can never find the initial conditions of an object.

d. Uncertainty is probabilistic and used to measure risk in chance events.
