5) When heated in a flame, the element Indium emits electromagnetic radiation with a distinctive indigo blue
grandymaker [24]

Answer:

\lambda=451nm

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to solve this problem by using the following equation, defined in terms of energy, Planck's constant, wavelength and speed of light:

E=\frac{hC}{\lambda }

Thus, we solve for the wavelength as shown below:

\lambda=\frac{hC}{ E}

And finally plug in the energy, Planck's constant and speed of light to obtain:

\lambda=\frac{6.6261 x 10^{-34} m^2 kg / s*3x10^8m/s}{4.405x10^{-19}m^2kg/s^2}\\\\\lambda=4.513x10^{-7}m*\frac{1nm}{10^{-9}m} \\\\\lambda=451nm

Regards!

Why does increasing the number of trials increase confidence in the results of the experiment?
valkas [14]
<span>It rises confidence for the reason that the more times you conduct the similar experiment over and over should either demonstrate your hypothesis right and wrong and remove any random incidences that might touch your results. Meaning it permits to have a more accurate measure or conclusion.</span>

10. Which would make the best aquifer?
Levart [38]

c. sandstone in the zone of saturation

Explanation:

The best aquifer of all is a sandstone in the zone of saturation. An aquifer is a porous and permeable formation where groundwater can accumulate.

  • To be a good aquifer, a rock or soil must be porous and permeable.
  • Porosity is the amount of void spaces present in a rock.
  • Permeability is the inter-connectivity of the pore spaces.

The zone of saturation is the zone below the water table where water is always present underground.

  • Sandstones have high porosity and permeability.
  • They are good aquifers when found at the zone of saturation.
