Aspring with spring constant 13.1 n/m hangs from the ceiling. a ball is suspended from the spring and allowed to come to rest. it is then pulled down 10.0 cm and released. the ball makes 22.0 oscillations in 20.0 seconds.
what are its (a) mass and (b) maximum speed?

Explanation:

spring constant, K = 13.1 N/m

22 oscillations in 20 seconds

time taken to complete one oscillation is called time period.

T = 20 / 22 second = 0.909 seconds

(a) let m be the mass.

The formula for the time period is

m = 0.275 kg

(b) maximum speed, v = ω A = 2π A / T

v = ( 2 x 31.4 x 0.1) / 0.909

v = 0.691 m/s

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

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.
