An ascending elevator, hanging from a cable, is coming to a stop. Which forces are acting on the elevator? In which direction are those forces?

Explain how are functions used in everyday life.

Consider a submerged curved surface. Explain how you would determine the vertical component of the hydrostatic force acting on this surface.

Of what value is this complex life cycle to Paragonimus?

Use the given Minitab display, which results from the head injury measurements from car crash dummies listed below. The measurements are in hic (head injury criterion) units, and they are from the same cars used for Table. Use a 0.05 significance level to test the given claim.

Test the null hypothesis that head injury measurements are not affected by an interaction between the type of car (foreign, domestic) and size of the car (small, medium, large). What do you conclude?

For the problem, identify all the forces acting on the object and draw a free-body diagram of the object. You are driving on the highway, and you come to a steep downhill section. As you roll down the hill, you take your foot off the gas pedal. You can ignore friction, but you can't ignore air resistance.

What does the friction coefficient represent in flow over a flat plate? How is it related to the drag force acting on the plate?

The State Department is trying to identify an individual who speaks Farsi to fill a foreign embassy position. They have determined that 4% of the applicant pool are fluent in Farsi. What is the probability that they will have to interview more than 25 until they find one who speaks Farsi? More than 40?

Compare how particles are viewed in classical physics and in quantum mechanics.

Foreign trade is important to the United States. No country exports and imports more. However, there has been a large trade imbalance in many sectors. To measure the extent of the problem, an economist recorded the difference between exports and imports of merchandise (excluding military) for the years 1980 to 2012. Plot the trade balance.

. Explain what happens in a haploid life cycle.

Air flows past a symmetrical airfoil at an angle of attack of $5^{\circ}$. Is the $(a)$ lift and $(b)$ drag acting on the airfoil zero or nonzero?

A physics instructor Marshall Ellenstein walking barefoot on broken glass bottles in his class. Explain the physics concept that Marshall is demonstrating. Why is he careful to be sure that the broken pieces are small and numerous?
