The baltik sea
Explanation
Gotland is an island in the Baltic Sea approximately 90 km off the eastern coast of Sweden. It has been inhabited for a long time, probably dating back to the Stone Age. I hope it help good luck and stay safe
Use SAS(Side angle side ) rule.
Then cosine law i.e a^2=b^2+c^2-2*b*c*COSA
We will get a=69 mm
Now we have all sides use sine law
a/sinA=b/sinB
We will get B=60(deg)
And use the law: sum of all angles of triangle is 180(deg)
We will get C=75(deg).
Answer:
1. Conduction
2. Convection
3. Radiation
Explanation:
The 3 modes of heat transfer i an air conditioning system:
1. Conduction:
The transfer of heat by conduction takes place in solid and is when the conduction takes place as a result of direct contact in between the interacting material which transfer the heat energy from particle to particle thus conducting the heat through out the system.
2. Convection:
The other mode for the transfer of heat which takes place especially in fluids - gases and liquids is through the technique of convection in which the transfer of heat takes place by the circular motion of the atoms and molecules of the fluid which carries the heat energy and results in the distribution of the heated fluid in the entire system thus transferring all the heat energy in the entire system.
3. Radiation:
The third mode of heat transfer in the air conditioning system is through radiation. This method transfers the heat by making use of the electro-magnetic radiation in the infra red spectrum where the waves of the spectrum transfers the heat energy with the help of a medium or without any medium at all.
Thus making the radiation method of heat transfer as the only method out of the three methods which does not require the material medium for the transfer of heat energy.
