The deepest point in the ocean is 11 km below sea level, deeper than MT. Everest is tall. What is the pressure in atmospheres at this depth?

The highest that George can suck water up a very long straw is 2.0 m. (This is a typical value.) What is the lowest pressure that he can maintain in his mouth?

The record low sea-level barometric pressure ever recorded is 25.8 in. of mercury. At what altitude in the standard atmosphere is the pressure equal to this value?

State the type of measurement in each of the following statements: My dog weighs $12$ kg.

An organism that lives in the extreme conditions of a deep sea vent would most likely be considered a(n) A. archaea. B. bacterium. C. retrovirus. D. bacteriophage

State whether the following function is increasing, decreasing, or neither:

Height above Earth's sea level as a function of atmospheric pressure (assumed nonzero)

Simplify the given exercise below:

$$\sum_{k=0}^{10}(-1)^k\left(\begin{array}{c} 10 \\ k \end{array}\right)(\log x)^{10-k}(\log y)^k .$$

Write an equation of each line. Write the final answer in slope-intercept form. Through $(-1,4), m=2$

To determine an athlete's body fat, she is weighed first in air and then again while she's completely underwater. It is found that she weighs 690 N when weighed in air and 42 N when weighed underwater. What is her average density?

A 100 mL beaker holds 120 g of liquid. What is the liquid's density in SI units?

A tall cylinder contains 25 cm of water. Oil is carefully poured into the cylinder, where it floats on top of the water, until the total liquid depth is 40 cm. What is the gauge pressure at the bottom of the cylinder?

Calculate the buoyant force due to the surrounding air on a man weighing 800 N. Assume his average density is the same as that of water.

A research submarine has a 20-cm-diameter window 8.0 cm thick. The manufacturer says the window can withstand forces up to $1.0 \times 10 ^ { 6 } N$. What is the submarine's maximum safe depth in seawater? The pressure inside the submarine is maintained at 1.0 atm.

Sound travels slower in colder air. Why does the speed of sound depend on air temperature?
