1. Given three capacitors, C1 = 2.0 F, C2 =1.5 F, and C3= 3.0 F, what arrangement
of parallel and series connections with a 12-V battery will give the minimum
voltage drop across the 2.0-F capacitor? What is
the minimum voltage drop?

2. Suppose three parallel-plate capacitors,
whose plates have areas A1, A2, and A3 and
separations d1, d2, and d3, are connected in
parallel. Show, using only Eq. 242, that Eq. 243 is valid.

this one:

as we gain mass the force of gravity on us increases.

pls mark me as the ! : d

temp rises, and expansion

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.
