Two capacitors of capacitances 1.0 microfarad and 2.0 microfarads are each charged by being connected across a 5.0-volt battery. they are disconnected from the battery and then connected to each other with resistive wires so that plates of opposite charge are connected together. what will be the magnitude of the final voltage across the 2.0 microfarad capacitor?

1.67 V

Explanation:

Q = Capacitance

Q' = Capacitance after connecting in series

V = Voltage

= Voltage of battery = 5 V

As the plates opposite charge are connected together they are in series

The voltage across the 2 microfarad capacitor is 1.67 V

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.
