An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
According to Bellman's principle of optimality, the necessary condition for a policy to be optimal in a dynamic programming problem is that the policy must satisfy the principle of optimality. Therefore, the correct option is:
C) The policy must satisfy the principle of optimality. ;
The number of electrons that flow through an electric device delivering a current of 15.0 A for 30 seconds is approximately 2.81 × 1 0 21 . This is calculated by first finding the total charge using the formula Q = I × t and then dividing that by the charge of a single electron. This process allows us to determine the total number of electrons corresponding to the electric charge.
