The answer is A. Volcanoes and earthquakes often occur near place boundaries. Volcanoes are exit points for heat from the Earth's core. And Earthquakes are caused by the tectonic places colliding along another one. For example one tectonic plate would be slowly moving south, and another next to it could collide with the South-going plate while going North, and that is what causes Earthquakes.

which statement regarding the relative energies of monochromatic light with with λ = 800 nm andmonochromatic light with λ = 400
olga2289 [7]

Answer:

The correct answer is option A.

Explanation:

Energy of the photon of an electromagnetic radiation is give by Planck's equation:

E=\frac{hc}{\lambda }

Where:

h = Planck's constant

c = speed of light

\lambda = Wavelength of the photon's radiation

Energy of photon of 800 nm monochromatic light

\lambda = 800 nm=400\times 10^{-9} m

E=\frac{hc}{800 \times 10^{-9} m}

Energy per mole of photons:

E\times N_A=\frac{hc}{800 \times 10^{-9} m}\times 6.022\times 10^{23} mol^{-1}..[1]

Energy of photon of 400 nm monochromatic light

\lambda '= 400 nm=400\times 10^{-9} m

Energy per mole of photons:

E'\times N_A=\frac{hc}{400 \times 10^{-9} m}\times 6.022\times 10^{23} mol^{-1}..[2]

[1] ÷ [2]

\frac{E\times N_A}{E'\times N_A}=\frac{\frac{hc\trimes 6.022\times 10^{23} mol^{-1}}{800 \times 10^{-9} m}}{\frac{hc\times 6.022\times 10^{23} mol^{-1}}{400 \times 10^{-9} m}}

\frac{E}{E'}=\frac{1}{2}

E=\frac{1}{2}\times E'

What’s the answer I don’t know how to do it
Inessa05 [86]

Answer:

3.63m/s²

Explanation:

Given parameters:

Mass of box  = 8kg

Net force  = 29N

Unknown:

Acceleration of the box = ?

Solution:

To solve this problem, we use Newton's second law of motion which is stated as;

       Force  = mass x acceleration

 Acceleration  = \frac{Force }{mass}   = \frac{29}{8}  

Acceleration  = 3.63m/s²
