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.

melisa1 [442]

Answer:

If there are equal forces in both directions and there is no motion, the net force is 0 Newtons. This is because you'd be subtracting 100 from 100 which just equals 0.

kvasek [131]

Answer:

relates the electric field at points on a closed surface to the net charge enclosed by that surface.

Explanation:

Gauss Law states that overall electric flux of a closed surface is equivalent right to charge enclosed which is divided by the permittivity. In other words Gauss Law stress that

net electric flux that pass through an hypothetical closed surface is equivalent to overall electric charge present within that closed surface.

The Gauss law can be expressed mathematically as

ϕ = (Q/ϵ0)

Q = total charge within the surface,

ε0 = the electric constant
