A 15-m-long garden hose has an inner diameter of 2.5 cm. One end is connected to a spigot; $20 ^ { \circ } \mathrm { C }$ water flows from the other end at a rate of 1.2 L/s. What is the gauge pressure at the spigot end of the hose? A. 1900 Pa B. 2700 Pa C. 4200 Pa D. 5800 Pa E. 7300 Pa

A $\frac{5}{8}$-inch (inside) diameter garden hose is used to fill a round swimming pool $7.2$ m in diameter. How long will it take to fill the pool to a depth of $1.5$ m if water issues from the hose at a speed of $0.28$ m/s?

Determine the center and radius of the circle with the given equation.

$$x^2+y^2+8 x-10 y=23$$

Using the story earlier, answer the questions below:

(a) How was Maggie injured?

(b) How did Maggie and Dee each react to that dramatic experience?

Diffraction of $\mathrm{X}$ rays with $\lambda=154.2 \mathrm{pm}$ occurred at an angle $\theta=22.5^{\circ}$ from a metal surface. What is the spacing (in pm) between the layers of atoms that diffracted the $\mathrm{X}$ rays?

There are two carotid arteries that feed blood to the brain, one on each side of the neck and head. One patient's carotid arteries are each 11.2 cm long and have an inside diameter of 5.2 mm. Near the middle of the left artery, however, is a 2.0-cm-long stenosis, a section of the artery with a smaller diameter of 3.4 mm, For the same blood flow rate, what is the ratio of the pressure drop along the patient's left carotid artery to the drop his right artery?

There are two carotid arteries that feed blood to the brain, one on each side of the neck and head. One patient's carotid arteries are each $11.2 \mathrm{~cm}$ long and have an inside diameter of $5.2 \mathrm{~mm}$. Near the middle of the left artery, however, is a $2.0-\mathrm{cm}-$ long stenosis, a section of the artery with a smaller diameter of $3.4 \mathrm{~mm}$. For the same blood flow rate, what is the ratio of the pressure drop along the patient's left carotid artery to the drop along his right artery?

Solve the equation and check your answer.

Write the conjunctions and conjunctive adverbs in the following sentence.

Penguins have thick layers of fat under their skin and short, dense feathers; consequently, they can thrive in cold climates.

You water flowers outside your house. (a) Determine the flow rate of water moving at an average speed of $32 \mathrm{cm} / \mathrm{s}$ through a garden hose of radius $1.2 \mathrm{cm}$. (b) Determine the speed of the water in a second hose of radius $1.0 \mathrm{cm}$ that is connected to the first hose.

Water flows through a 4.0-cm-diameter horizontal pipe at a speed of 1.3 m/s. The pipe then narrows down to a diameter of 2.0 cm. Ignoring viscosity, what is the pressure difference between the wide and narrow sections of the pipe? A. 850 Pa B. 3400 Pa C. 9300 Pa D. 12,700 Pa E. 13,500 Pa
