Answer: The amount of light that enters the pupil is controlled by the Iris
Explanation:
Where are the calculations? please be more specific so we can helo you
In order to make an electric current flow it is necessary to have a source of the current or source of free electrons and also the circuit should be a close one or complete. When there is a break in a circuit, no current would flow in the whole system.
The ammeter reading (current) will decrease.
V=IR
I = V/R
so I is inversely proportional to R, i.e. increasing R will cause I to decrease
If an object is at equilibrium, the net force acting upon the object is 0 Newton.
