Precious throws a stone into a pond and watches as the transverse waves are formed in the water. The waves have a wavelength of 5cm and an amplitude of 0,4cm. She notices that three full waves pass a rock in 1,5s. Determine the frequency of the water wave?

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

that the claims meet official rules.

don't misinterpret the claims
