A student is using a resonance tube and determines that three resonances occur at distances of L1 = 0.494 m, L2 = 0.824 m, and L3 = 1.159 m below the open end of the tube. The frequency of the tuning fork used is 5.12 102 Hz. (Enter your answers to at least three significant figures.) HINT (a) Find the wavelength (in m) using distances L2 and L1. λ2-1 = m (b) Find the wavelength (in m) using distances L3 and L2. λ3-2 = m (c) Find the average wavelength (in m). λavg = m (d) Find the average speed of sound (in m/s). vavg = m/s

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

this could be newton#'s law of cooling. the cooling curve is exponential

i will answer your question if you answer mine

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
