Answer:
Calculate the mean monthly temperature by adding up the daily mean temperatures for each day of a month and then dividing that sum by the number of days in the month. For example, for the month of January, add up the 31 mean daily temperatures, then divide by 31.
Answer:
B. Their location on the Baltic Sea
Explanation:
Invasions from other powers had been taking place in the Baltic Nations for a very long time due to it's location.
Answer:
Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
Explanation:
The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.
L = σ(T^4)(4πR^2)
L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.
Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.
To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:
L_a = σ(T_a^4)(4πR_a^2)
L_b = σ(T_b^4)(4πR_b^2)
you can assume that L_a and L_b are equal:
σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)
Now, you can cancel the constants:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
as long as this relation between a and b is true, then the luminosity can be the same.
The town is which I live is Negotino, Republic of Macedonia. The is located in the driest part of the country, so it is very common that there's problems with water during the warmer part of the year. The landscape is mostly dominated by two things, vineyards and barren land which has the characteristics of a is semi-desert, so the town, and the municipality as whole, lacks in wood as well.
My two suggestions for making the town and the surrounding area more sustainable would be:
1. Planting the whole barren land with wild or semi-wild apricots
The wild and semi-wild apricots thrive in this climate, do not need any maintenance, don't have problems with high temperatures and droughts, nor with very low temperatures. From those apricots, the fruits can be used for production of juices and kompots, selling them for much lower prices in the municipality and throughout the country, so the municipality can get a significant income, income that can be used for improving the town's infrastructure and any projects. The shells of the apricots are excellent for heating, thus can be distributed to the households throughout the town as a material for heating during the winter. The trees will also contribute to better air quality and lower the effects of the strong winds.
2. Construction of water collectors
Construction of water collectors will be extremely useful, considering the semi-arid climate in the area. The water collected during the spring and autumn can be used for all sorts of things in the town, thus minimizing, or maybe even eliminating the water problem during the drier parts of the year.
The Ming emperors made it their capital in 1421 and it remained China's capital till 1912 when the Manchu Empire fell and SunYat Sen turned China into a republic.
