Amazon SNYS DMV - My DMV 14.udemy ClassMarker - Test NYC HEALTH +HOS... Which statement does the passage support? Question 15 of 190 Although most animals and some plants detect and respond to sound vibrations, the precise sensitivity that we call hearing is rare in the living world. It is highly developed only in birds and mammals, and the same operational system applies in all vertebrate auditory systems. Sound waves cause a liquid within the organism's auditory apparatus to vibrate. These vibrations are picked up by receptors that transmit signals to nerve cells. These cells then communicate the sound to the brain. Humans can hear vibrational frequencies of 20 to 20,000 cycles per second; cats respond to frequencies of up to 50,000 cycles per second; and porpoises and bats pick up frequencies of 100,000 cycles per second. O A. Ears are damaged by high frequencies. O B. Humans have the best hearing of all animals. O C. Cats and porpoises are adapted to hearing low frequencies. O D.…

The combustion of gasoline (octane) in a car engine can be represented by the following equation: 2C3H18(1) + 2502(g) --> 16CO2(g) +18H2O(g) a. What mass of oxygen is used up to burn a full tank of 36.00 kg of gasoline? b. Why might a vehicle that is calibrated to run perfectly at sea level run poorly at higher elevations? C. According to the Canadian Automobile Association, the average Canadian drives 20,000 km/yr. Assuming that distance, how many more kg of carbon dioxide are added to the atmosphere each year by a Toyota Tacoma (fuel economy of 12.8 L/100 km) than a Toyota Prius (4.52 L/100 km)? The density of gasoline is 0.719 kg/L.

The outlet emission rate of HCl is given in the table in the textbook for question 12-2 as 4.3 lb/hr. The DRE is most nearly ..   D)Calculate the concentration (grains/dscf) of particulates in the flue gas if the stack flow rate is 37,500 dscfm, oxygen in the flue gas is 7%, and the particulate emission rate is 20.3 lb/hr. Specify your numerical result to three decimal places, such as x.xxx. Do not include the units in the answer.
