Electrons are ejected from sodium metal by any light that has a wavelength shorter than 544 nm. What is the kinetic energy of an
wel

Answer:

KE=2.3 x 10⁻¹⁹ J

Explanation:

Given that

λ = 544 nm

λ' = 485 nm

The kinetic energy KE given as

KE= E - Ф

Where

E=\dfrac{hC}{\lambda'}

\phi=\dfrac{hC}{\lambda}

h= 6.626 x 10⁻³⁴

C=3 x 10⁸ m/s

Now by putting the values

KE=\dfrac{hC}{\lambda'}-\dfrac{hC}{\lambda}

KE=\dfrac{34.34\times 10^{-34}\times 3\times 10^8}{485\times 10^{-9}}- \dfrac{34.34\times 10^{-34}\times 3\times 10^8}{544\times 10^{-9}}

KE=2.3 x 10⁻¹⁹ J

This is kinetic energy.

Which situation is an example of transferring heat by means of convection?
fgiga [73]

A situation that involves the transfer of heat by means of convection must involve the exchange of fluid currents such as land and sea breezes.

Heat transfer by convection is a method of heat transfer by which heat is transferred between two bodies through through currents of moving fluids or gases.

The following are examples of heat transfer by convection;

  • land breezes cooling the sea at night
  • sea breezes cooling the land during the day
  • boiling of water
  • circulation of blood, etc

Thus, a situation that involves the transfer of heat by means of convection must involve the exchange of fluid currents such as land and sea breezes.
