A 4.0 µF capacitor and a 5.0 µF capacitor are connected in series across a 1.5 kV potential difference. The charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. Find the charge on each capacitor (in mC) and the voltage across each capacitor (in V). (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)

Two large, thin, metal plates of 0.5mx0.5m face each other. They are spaced 2cm apart and have equal but opposite charges on their inner surfaces.

a) if the magnitude E of the electric field between the plates is 700 N/C what is the magnitude of the charge on each plate?

b) Integrate E across the gap between the plates to find the potential difference V and hence the capacitance C.

c) Recalculate C using the parallel plate capacitator formula instead.

d) the energy density of the field between the plates?

e) the total energy of the field between the plates?

f) use C and V to calculate the energy stored in the capacitator to compare to the result of e

A bullet with a mass m b = 11.5 g is fired into a block of wood at velocity v b = 265 m/s. The block is attached to a spring that has a spring constant k of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass of the wooden block. From left to right, a bullet of mass m subscript b has a velocity of v subscript b with a velocity vector pointing directly to the right. The vector points toward a block that is attached on its right face to a spring of force constant k. The other end of the spring is attached to a fixed, vertical surface. mass of wooden block: kg

A novelty collision device known as the executive toy consists of five identical metal balls. When one ball swings in, after multiple collisions, one ball swings out at the other end of the row of balls. When two balls swing in, two swing out; when three swing in, three swing out, and so on-always the same number out as in. Suppose that one ball, with mass m, swing in and collide with the next ball with a velocity v. Why don’t two ball swing out at the other end with a velocity of v/2? Clearly establish the reasoning and physical principles to receive full credit.

Can someone explain to me what laws are being used here and how it relates to the question? Thank you.
