Answer:

The most precise is 0.0034 m ⇒ 1st answer

Explanation:

Lets revise the meaning of precise

Precision is referred as the closeness of two measurements to one

another.

Highest number with significant digit is the most precise

Ex: Highest significant of optical instrument is the Wavelength of visible (red)

light = 0.00006 cm

Hence the most precise device for measuring length is the given optical

instrument

The difference between accuracy and precise

Accuracy is how close a value is to its true value

Precision is how repeatable a measurement is

We have three numbers

0.0034 m, 45.6 m, and 1234 m

The least precise is 1234 m

The most precise is 0.0034 m

Light from a sodium lamp 1l = 589 nm2 illuminates two narrow slits. the fringe spacing on a screen 150 cm behind the slits is 4.

BartSMP [9]

d = 0.221 mm is the spacing (in mm) between the two slits..

here,

wavelength = 589 nm

D = 150 cm = 1.5 m

y = 4 mm

then ,

y = mλD/d

for m = `1

0.004 = 589*10^-9 * 1.5/d

d = 2.21*10^-4 m

d = 0.221 mm

slit spacing is 0.221 mm

The sesmic characteristics of a train depend on the speed of the train, the distance between the wheels, and the hardness of the ground beneath the rails.

Philadelphia attack efficiency aims to improve spacing It continues to lag despite offseason moves, and Harden could have single-handedly fixed these issues.

In a typical hydrogen bond, as atoms move further up the energy ladder, The distance between the energy levels decreases. For Scientists Working at Such Small Scales, these “charging times” are likely candidates for the cause of the distance effect.

A string is fixed at both ends and vibrating at 140 Hz, which is its third harmonic frequency. The linear density of the string

loris [4]

Answer:

Length of the string = 0.24 m

Explanation:

The frequency (f) of vibration of stringed instruments is related to the Tension (T) in the spring by the relation

fₙ = (n/2L)√(T/μ)
