5 MODEL#3: Understanding How SFs Propagate in Calculations. C. 4.0000 cm² 136.8 mm C. 3800. g f. 1.70×104 g/cm³ a. Calculate the volume (length x width x height) in units of mm³ (mm × mm x mm) for the large eraser shown below. Report your answer to as many digits as your calculator displays. 254.7 mm fufc 25.3 mm Jef b. Estimated uncertainties in measurements are at least ±1 value in last reported digit. Estimate the new volume if each of the above measurements were 0.1 mm larger (136.9 mm x 254.8 mm x 25.4 mm). 2 c. Starting from the left, which digit is the 1st digit in the answers from a & b that differ? If you report all the values that agree plus the 1st value where the answers disagree, how many SFs should you report?

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.…
