Why are the bacterial endospores placed on the paper strip and not directly in the fermentation broth?
Artyom0805 [142]
The bacterial endospores are microorganisms formed due to nutrient deprivation. These are placed first on a paper strip and not directly in the fermentation broth because these microorganisms are very resistance, thus, they need to adjust to the environment first before being acclimated to it.

What is the energy of a photon of violet light with a frequency of 7.57x10^14 s^-1?
Eddi Din [679]

Answer:

ΔE = 5.02 x 10⁻¹⁹ j

Explanation:

ΔE (photon) = h·f = (6.63 x 10⁻³⁴ j·s)(7.57 x 10¹⁴ s⁻¹) = 5.02 x 10⁻¹⁹ j

h = Planck's Constant = 6.63 x 10⁻³⁴ j·s

f = frequency (given) = 7.57 x 10¹⁴ s⁻¹

To what pressure must a gas be compressed in order to get into a 3.00 cubic foot
Troyanec [42]

Answer:

133.3atm

Explanation:

Given parameters:

Initial volume  = 400ft³

Final volume  = 3ft³

Initial pressure = 1atm

Unknown:

Final pressure  = ?

Solution:

To solve this problem, we  apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".

  Mathematically;

               P₁V₁ = P₂V₂

P and V are pressure and volume

1 and 2 are initial and final states;

   Insert parameters and solve;

                1 x 400  = P₂ x 3

                     P₂  = 133.3atm
