Due to the corona virus pandemic there has been a decrease in the demand for luxury goods especially in the airline industry where revenue has decreased,  a decrease in consumer income and factories have closed due to the virus causing a supply shortage to companies such as Apple and Toyota. Fully Explain this change using elasticity measurements and determinants (price elasticity and its relationship to revenue, price elasticity of supply and income elasticity of demand . Provide graphs and calculations to support your explanation.

The vapor pressure of liquid diethyl ether, C₂H₅OC₂H₅, is 100 mm Hg at 262 K. A 0.167 g sample of liquid C₂H₅OC₂H₅ is placed in a closed, evacuated 300. mL container at a temperature of 262 K.

Calculate what the ideal gas pressure would be in the container if all of the liquid diethyl ether evaporated.  mm Hg

Assuming that the temperature remains constant, will all of the liquid evaporate? _____ yes or no

What will the pressure in the container be when equilibrium is reached?  mm Hg

How is the coronavirus pandemic affecting wildlife? With fewer cars on the roads, and with parks and wildlife areas closed to the public for several weeks, the Stay-at-Home Order (shelter in place) likely affected some animal populations in urban areas.

describe two examples of how animals have been affected.
Make sure to include the type of animal affected, and how they are affected. If you have directly witnessed affected wildlife, you may use that as one example.

On a hot day with a temp of 35 celsius, you blow across the open end of an empty test tube and produce the fundamental standing wave for the air column inside the test tube. The test tube acts like a 22 cm pipe open at one end and closed at the other.

What is the fundamental frequency?

What is the frequency of the next possible Harmonic?

A person standing nearby records a sound level of 50 dB. What is the sound intensity measured by that person?
