As you can see by the Comments under the question,
Afscrappermomp5lzxc and I had some private correspondence
after I asked for additional information. It turns out that all three
resistors are in series in her circuit, and we can now go ahead
and solve the problem.

In a series circuit, there's only one possible path for the current
to follow on its trip from one side of the battery to the other side.
The electrical ' current ' is the same at every point in the circuit,
and also, all of the resistors in the circuit act as if there was only
ONE resistor, with a value equal to the SUM of all the individual ones.

So this particular circuit looks like it has one single resistor across
the battery, and its resistance is (4.0Ω + 3.2Ω + 3.4Ω) = 10.6 Ω .

That's wonderful. Now it's a piece-'o-cake to find the current.

One form of Ohm's Law says ...

Current = (voltage) / (resistance)

Current = (5 volts) / (10.6 Ω) = 0.472 Amperes (rounded)

Answer from: Quest

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
