What is the energy of a TV wave that NBC broadcasts, if it has a wavelength of 32 meters?

Chemistry
1 answer:
serg [7]2 years ago
8 0

Answer:

Explanation:

E = hc/λ

h = planck's constant = 6.66 x 10 ^ -34

c = speed of light = 2.98 *10^8 m/s

E = (6.66 x 10 ^ -34 )(2.98 *10^8)/32

  = 19.85 * 10 ^-26

   =0.62 x 10^-26

   = 6.2 x 10^-27 J

Which solution is a homogeneous mixture? sand and water salt and water salad dressing soil
Over [174]

Answer: Option (b) is the correct answer.

Explanation:

A solution whose constituent particles are uniformly distributed in the solution  is known as a homogeneous solution.

In a homogeneous solution, particles of one solute completely dissolves in the solvent. This solution is also known a true solution.

When sand and water are mixed together then after a certain interval of time sand particles will settle at the bottom. Therefore, they do not dissolve in water. So, it is not a homogeneous solution.

When salt and water are mixed together then the salt particles will dissolve in water. Therefore, it is a homogeneous solution.

Salad dressing is not a homogeneous solution as it contains different solutions like oil, lemon juice etc which does not dissolve when mixed together.

On the other hand, soil is also not a homogeneous solution because we can visualize the distinct layers present in a soil. These layers when mixed in a solution does not dissolve so they did not form a homogeneous solution.

Thus, we can conclude that out of the given options, salt and water is a homogeneous mixture.

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

these are the definitions so hope it helps you:

<u><em>carbon cycle</em></u><em> - Pathways through which carbon is recycled through the biosphere. </em>

<u><em>cellular respiration</em></u><em> - Process of breaking down glucose to obtain energy in the form of ATP. </em>

<u><em>photosynthesis</em></u><em> - Process by which specific organisms (including all plants) use the sun's energy to make their own food from carbon dioxide and water; process that converts the energy of the sun, or solar energy, into carbohydrates, a type of chemical energy. </em>
