Calculate the current in a circuit if 500 C of charge passes through it in 10 minutes. * (1 Point)
a) 0.83A
b) 0.083A
c) 8.3A
d) 83A

Choice a. Approximately on average.

Explanation:

The electric current through a wire is the rate at which electric charge flows through a cross-section of this wire.

Assume that electric charge of size flowed through a wire cross-section over a period of time . The average current in that wire would be:

.

For this question:

Therefore, the average current in this circuit would be:

.

However, the units in the choices are all in (for Amperes.) One Ampere is equal to one . It will take some unit conversations to change the unit of (coulombs-per-minute) to coulombs-per-second.

.

Hence, the most accurate choice here would be choice a.

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.
