Guys, please help me if your kind and if you want to be kind I will mark branliest just please help! Someone in your house is watching TV. You put your ear to the wall to listen to the TV. Then you walk into the room to watch TV. When you listen to the voices while in the room, they sound different than listening to them through the wall.

Why do the voices sound different when you listen to them through the wall?

Sound waves change frequency over long distances

Sound waves do not pass through solid materials

Sound waves travel at different speeds when traveling through different materials

Your ear processes sound differently when it goes through a solid.

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.

What is an example of a physical property?

Compare and contrast physical changes with chemical changes.
