Answer:

4m/s²

Explanation:

Initial velocity (u) = 0 m/s

Final velocity (v) = 8 m/s

Time taken (t) = 2 sec

Acceleration (a) = ?

We know

a  =  \frac{v - u}{t}  \\  =  \frac{8 - 0}{2} \\  =  \frac{8}{2}  \\  = 4 \: m |s ^{2}

Hope it will help :)

A physicist is calibrating a spectrometer that uses a diffraction grating to separate light in order of increasing wavelength (λ
cluponka [151]

Answer:

Explanation:

Given

N=3680 cm^{-1}

therefore slit spacing d=\frac{1}{N}=\frac{1}{3680}=2.717\times 10^{-4}\ cm

since d\sin \theta =n\lambda

for n=1

d\sin \theta =\lambda

Now,at \theta _1=12.9^{\circ},\Rightarrow \lambda _1=6.0657\times 10^{-7}\ m=606.57\ nm

at \theta _2=14.2^{\circ}\Rightarrow \lambda_2=666.5\ nm

at \theta _3=15^{\circ}\Rightarrow \lambda_3=703.21\ nm
