A music studio is next to a quiet room in a library.Erik practises the glockenspiel in the studio. Sometimes the sounds are too loud in the library and Aravindercomplains.He collects data, using a decibel meter, and records the loudness of thesound in decibels (dB) as shown below. Aravinder suggests the wall between the library and the studio is lined with foam.All of the options are the reasons why foam is useful EXCEPT? absorbs / muffles sound allows sound pass through insulates from sound foam is sound proof 8. Radeyah knows that birds have hollow bones like a tube.This helps birds to fly.She is investigating how the diameter of hollow tubes changes the strength of thetube.Here is her apparatus and her results as shown in the table below: Radeyah says her results are not very useful.The investigation can be improved by using different materials for the tubes.What other way can Radeyah improve her investigation? use a particular size of mass use a particular size of tube do not use papers repeat the investigation 9.
