A simple magnetic compass can be used
Answer:
It was significant because thanks to Miller's experiment, it was possible to test many years later and with modern techniques, the progress of the evolution of life on Earth.
Explanation:
In Miller's experiment, he subjected a mixture of methane, ammonia, hydrogen, carbon dioxide, nitrogen and water to strong electric shocks and high temperatures. He noted that organic molecules such as glucose, amino acids such as glycine, alanine, glutamic acid and aspartic acid were formed. Subsequently, in 2008 other scientists analyzed these compounds using more sensitive devices. Their analyzes found the formation of 20 amino acids (proteins) and 6 components found in the nucleus of the cells, thus checking the progress of the evolution of life on Earth.
Answer:
![r=k[UO_2^+]^2[H^+]](https://tex.z-dn.net/?f=r%3Dk%5BUO_2%5E%2B%5D%5E2%5BH%5E%2B%5D)
Explanation:
The given reaction is :-

According to the law of mass action:-
The rate of the reaction is directly proportional to the active concentration of the reactant which each are raised to the experimentally determined coefficients which are known as orders. The rate is determined by the slowest step in the reaction mechanics.
Order of in the mass action law is the coefficient which is raised to the active concentration of the reactants. It is experimentally determined and can be zero, positive negative or fractional.
The order of the whole reaction is the sum of the order of each reactant which is raised to its power in the rate law.
m = 2 = is order with respect to 
n = order with respect to H+
overall order = m+n = 3
n = 3 - m = 3 - 2 = 1
Rate law is:-
![r=k[UO_2^+]^2[H^+]](https://tex.z-dn.net/?f=r%3Dk%5BUO_2%5E%2B%5D%5E2%5BH%5E%2B%5D)
Answer:
Land gains heat energy faster than water. Because land absorbs more solar radiation .
