It keeps us from flying into outerspace.
Answer: Jupiter is the fifth planet in the solar system from the Sun and the largest in the Solar System. It is a gas giant with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. It has 67 moons and has rings that aren't too visible but still there. Jupiter is the fourth brightest object in the solar system and has the shortest day of all planets. Jupiter orbits the Sun once every 11.8 Earth years.
Answer:T= 2898*10^-5K
Explanation:
wavelength = 10cm
Using Wien's Law
maximum wavelength= 2898*10^-6/temp(K)
thus T=2898*10^-6/10*10^-2
T= 2898*10^-5K
this is the maximum observed temperature of 10 cm wavelength black body
since this temperature is close to the diurnal equilibrium temperature, that's why it not get much colder.
Recommended rates of potash for grazed grass are 60kg/ha and 30kg/ha of K2O for soil index 0 and 1 respectively. For soils with higher soil fertility levels no potash required.
Very large quantities of potash are removed in grass silage which must be replaced to maintain soil fertility and yield potential. The following is guide to typical potash offtakes from multi-cut silage systems.Low soil magnesium levels will affect grass yield as well as mineral balance in the animal. Apply 50-100 kg/ha MgO every three to four years at Mg index 0. Yield response is less certain at index 1 but magnesium application is justified in terms of insurance for grass yield and mineral balance for the animal, to maintain a soil magnesium index of 2.
Where lime is required and Mg levels are 0 and 1, use magnesian limestone as the most cost effective magnesium source. Where pH is satisfactory, specific magnesium fertilisers (see table below) should be used for soil improvement. Use water soluble forms of magnesium where rapid plant uptake is required.
