30° South, 60° east I'd say.
Tycho Brahe ( 1546 - 1601 ) was a Danish astronomer known for his accurate astronomical and planetary observations. Tycho tried to produce a model with the best of both Ptolemy ( earth-centered solar system ) and Copernicus ( sun-centered solar system ).
Answer: B ) observation.
Answer AND Explanation:
Fossil fuels are a type of naturally non-renewable energy sources that are formed from the remains of living organisms. The non-renewable resources are those that are not regenerated in nature at rates equivalent to their use. Fossil fuels have been used by man on a small scale for a long time. The main forms of fossil fuels are petroleum oil, natural gas and coal. Coal forms the major bulk of the fossil fuel deposits.
The correct answer is k = 1.5 *10^12.
The potential difference between two half cells in an electrochemical cell is measured by the cell potential, or Ecell. The capacity of electrons to go from one half cell to the other is what determines the potential difference. The Nernst equation is used to determine the concentration of one of the cell's components or to compute the voltage of an electrochemical cell. Ecell = E0cell - (RTnF)InQ is the Nernst formula. Cell potential is ecell. A galvanic cell or voltaic cell is an electrochemical device that transforms the chemical energy of spontaneous redox reactions into electrical energy. electrical cell A voltaic cell is an electrochemical device that produces electricity through chemical processes.

Answer:
rainbow is regarded as one of the most spectacular light shows observed on the earth. A rainbow is a multicoloured arc made due to the striking of light on water droplets. Rainbow is produced after the rain, by reflection, refraction and light dispersion process in droplets of water. All such events develop a light spectrum in the sky are called rainbow.
The necessary conditions for the formation of the rainbow:
Presence of raindrops.
Sun should be at your back to observe the rainbow
Because of the dispersion, white light separates into different colors when entering the raindrop, causing less refraction of red light than blue light.
Formation of the rainbow:
Light rays, reach the drop near its top level. At first, there is refraction, then the dispersion of white light into colours of a different wavelength.
The violet is the most deviated and red is the least deviated colour.
Reaching the opposite side of the drop, each colour is refracted back into the drop due to the complete internal reflection that hits the drop surface.
Every colour is refracted to the air again.
We experience the rainbow when we observe in between 42-40 degrees.
