If electromagnetic radiation has a frequency of 2.0×1015s−1, what is the radiation’s energy?(1 point)
Alika [10]
  • Frequency=v=2×10^15Hz
  • Energy=E

Using planks quantum theory

\\ \sf\longmapsto E=hv

\\ \sf\longmapsto E=6.626\times 10^{-34}Js\times 2\times 10^{15}s^{-1}

\\ \sf\longmapsto E=13.252\times 10^{-19}J

\\ \sf\longmapsto E=1.3\times 10^{-18}J

__is when two genetic sequences bind together because of the hydrogen bonds that form between the base pairs ​
Anettt [7]

Answer:

I would say that it is the bond called complementary hydrogen bonds

Explanation:

The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.

Explain why some parts of our planet have very little seasonal change.
rosijanka [135]
Some parts of the planet undergo very little seasonal change due to their proximity to the equator and the poles. This means that their position relative to the sun and the earth's rotation varies hardly at all.

Alex17521 [72]

Answer: The cells that make up the digestive, muscular, skeletal, reproductive, and excretory systems all need oxygen from the respiratory system to function, and the cells of the respiratory system—as well as all the other systems—need nutrients and must get rid of metabolic wastes.

What NaCl NaCl concentration results when 249 mL 249 mL of a 0.850 M 0.850 M NaCl NaCl solution is mixed with 667 mL 667 mL of a
tamaranim1 [39]

Answer:

The answer to your question is 0.54M

Explanation:

Data

Final concentration = ?

Concentration 1 = 0.850 M

Volume 1 = 249 ml = 0.249 l

Concentration 2 = 0.420 M

Volume 2 = 0.667 M

Process

1.- Calculate the number of moles in both solutions

Number of moles 1 = Molarity 1 x Volume 1

                               = 0.850 x 0.249

                               = 0.212

Number of moles 2 = Molarity 2 x Volume 2

                                = 0.420 x 0.667

                                = 0.280

Total number of moles =  0.212 + 0.280

                                      = 0.492

2.-Calculate the final volume

Final volume = Volume 1 + Volume 2

Final volume = 0.249 + 0.667

                      = 0.916 l

3.- Calculate Molarity

Molarity = 0.492 / 0.916

Molarity = 0.54
