Answer:
Explanation:
Given that,
Efficiency of heat engine, 
Temperature of hot source, 
We need to find the temperature of cold sink i.e. 
. The efficiency of heat engine is given by :
So, the temperature of the cold sink is 256.2°C. Hence, this is the required solution.
Pivots Points are price levels chartists can use to determine intraday support and resistance levels
Answer:
anions
Explanation:
The other are families of the periodic table.
An anion is a negatively charged ion.
Answer:
Gamma Rays
Explanation:
Gamma rays have the highest energies the shortest wavelengths and the highest frequencies. They have the highest energies because they have the highest frequencies, the higher the frequency the more energy. ( I think, maybe double check with other answers )
Good Luck :)
politics. Famous possible eg is of Werner Heisenberg in WW2. He delayed German attempt to build a nuclear bomb. US did build one ... hiroshima and nagasaki.
