We say that visible light has wavelength from 400nm to roughly 800nm. What is the biggest "energy-jump" (excited) for an atom if

icang [17]

Answer:

$4.98\cdot 10^{-19} J$

Explanation:

The energy of the emitted photon is inversely proportional to its wavelength, according to the equation:

$E=\frac{hc}{\lambda}$

where

$h=6.63\cdot 10^{-34} Js$ is the Planck's constant

$c=3.0\cdot 10^8 m/s$ is the speed of light

$\lambda$ is the wavelength

This means that the biggest energy is released when the wavelength is the shortest. For a photon of visible light, the shortest wavelength is

$\lambda=400 nm = 400\cdot 10^{-9} m$

So, substituting into the equation, we find the corresponding energy:

$E=\frac{(6.63\cdot 10^{-34})(3\cdot 10^8)}{400\cdot 10^{-9}}=4.98\cdot 10^{-19} J$

Arturiano [62]

Answer:

Biotic factors are the living component of an environment while abiotic factors are the non living component of an environment.

Biotic factors of Mono lake include plants, animals, fungi, algae and bacteria

Abiotic factors of Mono lake include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability.

While the biotic and abiotic factors on Land inhabited by humans including Me are :

Biotic factors-Plants ,animals, bacteria

Abiotic factors-Sunlight, heat/ temperature, Climate, weather, water sources.

he primary coil of a transformer is connected to 240 V ac supply. The induced secondary voltage is 60 V. If the ac current in th

vovikov84 [41]

Answer:

Secondary current is 8A

Explanation:

Data :

Primary supply = Vp = 240 V

Secondary supply = Vs = 60V

Primary current = Ip = 2A

Secondary current = Is = ?

Formula : Vp × Ip = Vs × Is

So for secondary current formula becomes

Is = (Vp/Vs)×Ip = (240/60) × 2

Is = 4 × 2 = 8A
