  • 254nm is equivalent to 2.54 × 10-⁷metres.
  • The frequency of a radiation that has a wavelength of 254nm is 1.18 × 10¹⁵Hz

<h3>How to calculate frequency?</h3>

Nanometers is an SI subunit of length equal to 10-⁹ metres. It has a symbol of nm.

The conversion factor of metres to nanometers is as follows:

1 nanometres = 1 × 10-⁹ metres

Hence, 254 nanometers is equivalent to 2.54 × 10-⁷metres.

The frequency of a wave can be calculated using the following formula:

wavelength = wave velocity/frequency

frequency = 3 × 10⁸ ÷ 2.54 × 10-⁷

Frequency = 1.18 × 10¹⁵Hz

Therefore;

  • 254nm is equivalent to 2.54 × 10-⁷metres.
  • The frequency of a radiation that has a wavelength of 254nm is 1.18 × 10¹⁵Hz

What is the volume of 14.0 g of nitrogen gas, N2, at a pressure of 2.00 atm and temperature of 27.0 degree celsius
Lelu [443]
P = 2.00 atm = 2026.50hPa
T = 27°C = 300K
m = 14.0g              |
Mr = 28g/mol         |      n = m/M = 14g/28g/mol = 0,5mol
R = 83.1 [hPa*L]/[mol*K]

pV = nRT

        nRT        0,5mol * 83.1[hPa*L]/[mol*K] * 300K
V = ---------- = ----------------------------------------------------------- = <u>6.15L</u>
           p                           2026.5hPa

Which regions of the world seem to be suffering most from loss of species ?
Lana71 [14]

Answer:

The most dangerous area for animals and plants is the one that contains the greatest biodiversity on the planet: Southeast Asia. In this region are the five most affected countries in the world: Malaysia, Brunei, Singapore, Indonesia and Thailand. The Atlantic rainforests of Brazil are also very affected, this is due to the fact that great catastrophes have occurred in these places lately, such as the massive fire in the Amazon, and the floods that occurred after the tremendous absence of vegetation that these places suffered.

Explanation:

Also on the other hand, the regions with the highest extinction are those that carry out little environmental policies where care has not been taken for species that are in danger of extinction, as happens, for example, in those islands such as the Galapagos Islands, which are subject to severe fines for harm turtles.
