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.
Answer:
Cold and harsh winters exist in this region, which is known for large cities and universities.
Explanation:
The Northeast of the United States is the most developed and most densely populated region of the country. This regions is by far the smallest of the five major regions of the United States. The Northeast region borders Canada on its north, the Atlantic Ocean on its east, the Southeast region on its south, and the Great Lakes area from the Midwest region in its west.
The climate in this part of the country is known for its fresh and pleasant summers. There is solid amount of precipitation throughout the year. The winters tend to be very cold and harsh, with temperatures often going below -30 C degrees, and intense snowfall being a common occurrence.
As mentioned, this region is very densely populated. The main reason for this is that it is the economic center of the United States, so there are large urban areas in it, and the landscape is dominated by settlements. Some of the largest cities in the Northeast are new York, Boston, Philadelphia, and Buffalo.
There are also numerous student towns in the area, mostly on places further away from the large urban areas. Millions of students visit these universities each year, and they are predominantly with very high reputation.
Answer:
An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout.
Explanation:
For instance, a simple light switch opens and closes the circuit that connects a light to a power source. When you build a circuit, it's a good idea to disconnect the battery or other power source when the circuit is not in use.
