Using Archimedes's Principle. A solid, homogeneous sphere with a mass of m0, a radius of r0, and a density of ρ0 is placed in a container of water. Initially the sphere floats and the water level is marked on the side of the container. What happens to the water level, when the original sphere is replaced with a new sphere which has different physical parameters? Notation: r means the water level rises in the container, f means falls, s means stays the same. Combination answers like 'r or f or s' are possible answers in some of the cases.

The new sphere has a mass of m < m₀ and a radius of r > r₀.
The new sphere has a density of ρ > ρ₀ and a mass of m < m₀.
The new sphere has a density of ρ > ρ₀ and a radius of r < r₀.

A) A plastic block that has a length of 0.5 m, a width of 0.26 m, and a height of 0.33 m, and has a density of 670 kg/m3 floats in both water and oil. If the plastic block is floating at the surface of a tank of water (which has a density of 1000 kg/m3), what is the distance from the top of the block to the surface of the water?If the plastic block is floating at the surface of a tank of oil (which has a density of 900 kg/m3), what is the distance from the top of the block to the surface of the oil?

B) A cargo barge is loaded in a saltwater harbor for a trip up a freshwater river. If the rectangular barge is 2.50 m by 20.0 m and sits 0.800 m deep in the saltwater harbor, how deep will it sit in the freshwater river?

You measured the force between two charged pith balls where the pith balls were of the same size and mass. Your assumption was that the charge on the balls was the same. Now, you charge the balls so that they hang a distance r apart. Then you step out to get a drink of water, and when you return, you find the distance between the pith balls is half what it was before you got a drink. In terms of the length L, the charge Q, and the original angle θ, find the new charge on the pith balls and the new angle at which they hang.

Make a phasor diagram for an LRC circuit 5000 Hz if voltage across LC is 4.0 V, voltage across a resistor is 9.0 V, peak current is .09 A, and the phase difference between R to LC is 6.3 radians. I always rate for helpful answers

Describe the reduction in the spherical aberration for a plano-convex lens for the special case of collimated light (parallel light) focused down to a focal point.

Which orientation of the lens gives the least spherical aberration and why?

Show ray diagrams

Describe how and axial-GRIN lens can further reduce the spherical aberration. Again show a qualitative ray diagram.

Consider the matrix methode for a single thin lense, ie, make the same assumption that we made when we developed the lensmaker formula.

Use this to determine the (simple) System Matrix, A, for the thin lense.

Do the entries in this System Matrix make sense?

What is the determinant of the thin lense System Matrix?
