You illuminate a slit with a width of 0.0549 mm with a light of wavelength 735 nm and observe the resulting diffraction pattern

spayn [35]

Answer:

Explanation:

Given

slit width $d=0.0549\ mm$

wavelength of light $\lambda =735\ nm$

Screen is placed at a distance of $D=2.85\ m$

The angle for the first minima is given by

$\sin \theta _1=\frac{m\lambda }{d}$

for m=1

$\sin \theta _1=\frac{1\times 735\times 10^{-9}}{0.0549\times 10^{-3}}$

$\sin \theta _1=0.0133$

and one half of central maxima is given by

$Y=D\sin \theta _1$

$Y=2.85\times 0.0133$

$Y=0.0381\ m$

Width of central maxima $=2Y$

$Width=0.0762\ m\approx 7.62\ cm$

A light-year is a unit of<br> a. time.<br> c. mass.<br> b. distance.<br> d. density.

lana [24]

Answer: The correct answer is Option b. Distance.

Explanation:

Scientists and astronomers use this unit to measure the distance in space. A light year is a unit of distance and not time because light travels very fast and it travels a lot of distance in one year.

Light year is basically defined as how far the beam of light travels in a year.

Therefore, this light year is a unit of distance. Hence, the correct option is option b.

$1\text{ light year}=5.879\times 10^{12}miles$

Hook's law describes an ideal spring. Many real springs are better described by the restoring force (FSp)s=−kΔs−q(Δs)^3, where q

kvasek [131]

Answer

given,

k = 250 N/m

q = 900 N/m³

(FSp)s=−kΔs−q(Δs)^3

work done = Force x displacement

$W = \int {F. dx}$

limits are x = 0 to x = 0.15 m

work done

$W = \int_0^{0.15} (k x + q x^3)\ dx$

$W = [\dfrac{kx^2}{2}+\dfrac{qx^4}{4}+ C]_0^0.15$

$W = \dfrac{300\times 0.15^2}{2}+\dfrac{900\times 0.15^4}{4}$

W = 3.375 + 0.1139

W = 3.3488 J

b) % cubic term = $\dfrac{0.1139}{3.3488}$

% cubic term = $3.4\ %$
