PLS HELP. 5. You're holding a sound sensor in your hand as you leave the library. The sensor display reads 40 dB inside the library. After you walk out the front door, the sound of traffic on the busy street causes the sensor to read 80 dB. How many times louder is it outside the library compared with inside? (8 points) no weird links pls

we know that difference of 10 dB represents 10 times louder sound, so by applying this,

the difference is 40 db means 10 × 10 × 10 × 10 times louder sound,

hence, the sound outside the library is 10000 times louder than the sound in library.

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
