Your friend, an artist, has been thinking about an interestingway to display a new wind sculpture she has just created. In orderto create an aural as well as visual effect, she would like to usethe wires needed to hang the sculpture as a sort of a stringinstrument.
She decides that with two wires and some luck, the wires will sounda C-major dyad (C - 262Hz, G - 392 Hz) when the wind blows (note: Adyad is part of a chord.). Her basic design involves attaching apiece of wire from a hook on the ceiling, attaching a second pieceof wire to the first wire, and then hanging the 50 pound sculpturefrom the second wire. Your friend tells you that she has beensuccessful in hanging the sculpture but not in "tuning" the sound.Desperate for success, she knows you are taking physics and asksfor your help. Before you tackle the analysis, you use yourknowledge of waves to gather some more information. You takesamples of the wires back to your lab and measure their linear massdensities and find them to be 5.0 g/m and 8.3 g/m. What is youradvice? Assume that the junction of the two wires can'tvibrate.

The recommended dosage for pain reliever containing acetaminophen, such as Tylenol, is 2 tablets taken every 360 minutes. If each tablet contains 500.0 mg of acetaminophen, how many kilograms can be safely taken in a 24-hour period?

genetics and tests observed data against

the probability of those values?

A. ANOVA

B. standard deviation

C. chi-square testosterone

The common pain relievers asprin (C9H8O4), acetaminophen (C8H9NO2) and naproxen sodium (C14H13O3Na) are all available in tablets containing 200.0 mg of the active ingredient. Which compound contains the greatest number of molecules per tablet? How many molecules of the active ingredient are present in each tablet?

A) how many moles of c are present in 2.50 moles of naproxen Formula C14H14O3
B) how many moles of H are present in 0.458 mol of naproxen Formula C14H14O3
c) how many moles of O are present in 0.065 moles of naproxen formula C14H14O3

How many moles are present in 10g of Na2SO4

1. A 4.00 L flask at 25.0 ^oC contains argon at a partial pressure of 0.0850 atm. What would be the partial pressure of argon after we add 1.00 g of argon gas to the flask without changing Temp or Volume?

2. A mix of N₂, O₂, CO₂ and argon gas is contained in a 40.0 L container. The total pressure is 1.80 atm. T = 25.0 degrees C. The partial pressure of O₂

is 0.600 atm. How many grams of O₂ are present? Assume ideal behavior.

3. A balloon containing N₂ gas has volume 4.80 L at a temperature 32.0 ^oC. The temperature is changed to -28.0 ^oC while still at a constant pressure of 762 torr. What will be the balloon’s new volume?

1. A balloon containing N₂ gas has volume 4.80 L at a temperature 32.0 ^oC. The temperature is changed to -28.0 ^oC while still at a constant pressure of 762 torr. What will be the balloon’s new volume?

2.One mole of nitrogen gas at one atmosphere of pressure and 25 ^oC. How can a scientist increase the pressure of the gas

a. Hold the temperature constant and increase volume b. Hold the temperature constant and decrease the volume c. Hold the volume constant and decrease temperature

d. Hold the volume constant and decrease temperature

3.In two flasks of having equal volume, sample A contains H₂ gas at 55°C and 2.00 atm and sample B contains O₂ gas at 55°C and 2.00 atm. Which statement is FALSE?

3)Suppose a balloon was released from the ground and rose to such a height that both the atmospheric pressure and atmospheric temperature decreased. Which statement is TRUE?

A) Both the temperature and pressure changes act to increase the balloon's volume.

B) Both the temperature and pressure changes act to decrease the balloon's volume.

C) The temperature change acts to decrease the balloon's volume and the pressure change acts to increase the balloon’s volume.

D) The temperature change acts to increase the balloon's volume and the pressure change acts to decrease the balloon’s volume.

EXPLAIN YOUR ANSWER!

A balloon of gas has a pressure of 1.72 atm, temperature of 35 oC and volume of 2.9 L. If the temperature decreases to 18 oC and the pressure increase to 3.51 atm, what is the new volume in L?
