Acertain parallel plate capacitor whose plate separation is 0.15 mm is hooked up to a 10 volt battery and fully charged. the wires are then disconnected from the battery, and the plates are pulled apart until the voltage across the plates reads 25v. what is the new plate separation? (hint: when the capacitor is disconnected from the battery, the charge on the plates is "locked" in)

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.

its a circle not a square that's simple silly.
