Pitching Machine Package
help please!! chemistry?
1.) in an experiment on hearing in animals, a scientist wants to see if a certain pitch will elicit a response in humans. He sets up the machine next to a man, turns it on, and observes no response by that man, verbal or otherwise, He puts the equipment away, and he concludes that the pitch is too high to be audible. why is this an invaild conclusion?
Write out the equation and fill in the appropriate data. your answers should be labeled with appropriate units.
2.) international Mail Carriers, an overnight delivery service, chargers $1.00 per cubic centimeter (cm)^3. How much will it cost to send a package that is 13cm wide, 8 cm wide, 8 cm long, and 2cm deep?
3.) u.s quick delivery charges $0.10 per cubic inch (in^3) for the same service. How much will it cost to send the same package? ( the package is 13 Cm wide, 8 cm long, and 2cm deep.)
1) You don't know if the machine even emitted the sound in the first place. You have to prove it actually made a sound by detecting it somehow.
2) (13cm)*(8cm)*(2cm)*1.00 = $208
3) (13cm)*(8cm)*(2cm)*.10 = $20.8
Please be sure to make me the best answer. :]
