The distance between Saturn and the Sun is about 1.4 billion km ( 1.429 billion km ). It is 11 times the distance between Earth and the Sun.
1.429 * 10^9 km = 1.429 * 10^12 m ≈ 1.4 * 10^12 m
Answer: 1.4 * 10^12 m ( using 2 significant figures )

Calculate the wavelength (in nm) of light that produces its first minimum at an angle of 21.0° when falling on a single slit of
Cerrena [4.2K]

To solve this problem it is necessary to apply the related concepts to the principle of overlap, specifically to single slit diffraction experiment concept.

Mathematically this can be expressed as:

dsin\theta = m\lambda

Where,

d = Width of the slit

\lambda =Wavelength

\theta = Angle relative to the original direction of the light

m = Any integer which represent the order of the equation (number of repetition of the spectrum)

To solve the problem we need to rearrange the equation and find the wavelength

\lambda = \frac{dsin\theta}{m}

Our values are given as,

d = 1.46\mu m = 1.46*10^{-6}m

\theta = 21\°

m = 1

Replacing in our equation we have,

\lambda = \frac{dsin\theta}{m}

\lambda = \frac{(1.46*10^{-6})sin(21)}{1}

\lambda = 5.232*10^{-7}m

\lambda = 523.2nm

Therefore the wavelength is 523.2nm

While 75-kg Anthony roller skates at 3 m/s, 60-kg Sue jumps into his arms with a velocity of 5 m/s. How fast does the pair go to
anzhelika [568]

Apply conservation of linear momentum

\\ \rm\Rrightarrow m1v1+m2v2=(m1+m2)V3

\\ \rm\Rrightarrow 75(3)+60(5)=(75+60)V3

\\ \rm\Rrightarrow 225+300=135v3

\\ \rm\Rrightarrow 525=135v3

\\ \rm\Rrightarrow V3=3.89m/s
