A 5-liter container of crude oil spills in the ocean. It has a mass of 4.10 kg. What is its density? If 1 liter of ocean water has a density of 1 03 kg, does the crude oil sink or float? Explain.

How does the movement of ocean currents explain the fact that much of western Europe has a mild, wet climate?

Put the following parts of the ocean floor in order from least to greatest depth: abyssal plain, continental shelf, mid-ocean ridge, trench, continental slope.

If the electric field in free space is $\mathbf{E}=E_{0}(\hat{\mathbf{x}}+\hat{\mathbf{y}}) \sin [(2 \pi / \lambda)(z+c t ) ]$ with $E_{0}=20$ volts/m, then the magnetic field, not including any static magnetic field, must be what?

How does the movement of ocean currents explain the mild, wet climate in much of western Europe?

Mitochondrial DNA is inherited from the father.

The rocket is traveling around the earth in free flight along the elliptical orbit. If the rocket has the orbit shown, determine the speed of the rocket when it is at A and at B.

In what ways is the ocean at 1,000 meters deep different from the ocean at the surface in the same location?

Graph $y=x^{2}$ in the graphing window $-10 \leq x \leq 10$, $-10 \leq y \leq 10$, without drawing the x- and y-axes. Adjust the graphing window for $y=2(x-1)^{2}+3$ so that (without the axes showing) the graph looks identical to that of $y=x^{2}$.

Draw all possible skeletons for a 6-C compound with

A 5-C chain and 2 double bonds,

Discuss the validity of each statement. If the statement is always true, explain why. If not, give a counterexample. If a Markov chain is regular, then it is absorbing.

A certain fluid has a density of 1 080 kg/m$^3$ and is observed to rise to a height of 2.1 cm in a 1.0-mmdiameter tube. The contact angle between the wall and the fluid is zero. Calculate the surface tension of the fluid.

Identify the conic section that the equation represents.

$$\frac { ( x + 2 ) ^ { 2 } } { 6 ^ { 2 } } + \frac { ( y - 7 ) ^ { 2 } } { 8 ^ { 2 } } = 1$$
