I've been tasked with constructing a bridge that must support the weight of a tennis ball.

-the bridge should try to maximize length

-only 8 sheets of paper and 18" of tape can be used

- the bridge cannot be taped down to the table (abutments)

- cutting the paper is allowed

ANY IDEAS ARE GREATLY APPRECIATED!

For years before the new $159 headphones release, I ve been searching for a pair of completely wireless earbuds, but for a reasonable price.

I was just wondering would having an armored car with bullet resistant glass be detrimental in the case of a car accident ( because Windows cannot be punched out for easy access to potential victims.

If force=m*a, and a=🔺v/t, where is energy needed. I mean, I know that acceleration does require energy, but I was wondering if there was a law/formula that stated this

Are there any products out on the market that you can wear while eating to protect your teeth from corrosion from acidic foods. (Lemon, pineapples, etc.)

I think that it would change into heat energy due to friction when the sound waves interact with matter, but also believe it could change into energy of motion due to the sound bounce off of an object. Are either of these right? Any thoughts are appreciated

I'm looking to preform chemistry experiments that will put to use the lab ware I have purchased( beakers,round bottom flasks, Erlenmeyer flasks, burners, and purchased chemicals. I have intermediate textbook chemistry knowledge, but am Looking for experiments other than what I already found( whoosh bottle, hot ice, electrolysis of water, decomposition of h2o2) that will help expand my current knowledge of chemistry.

IM LOOKING FOR a DRIVING SIMULATOR THAT FOLLOWS DRIVING LAWS (SPEED LIMIT, LANES, ETC.) THAT IS COMPATIBLE WITH A MAC AND A LOGITECH MANUAL TRANSMISSION STEERING WHEEL.

The valve was used in a video by nurdrage on YouTube called making hydrochloric acid. It prevented backflow but was never referred to by name.

i am in urgent need of a science fair project idea that test more then one item (eg. what cup keeps heat in the longest?) that doesn't involve plants (have only 9 days to do it)

i am wondering how much salt would make a quarter float density 8.96

I Have to read night for school and bought the iBook but it didn't come with a table of contents .
