Explanation:
As we know that the maximum of thermal energy will be converted into mechanical energy.( The thermal energy will be given to us by engine.)
But the total thermal energy will not be converted into the mechanical energy, there will be some lost of energy. The lost of mechanical energy will be in multiple forms. 2 of them are
1.Heat : The mechanical energy heats up the engine and then it will lost some energy.
2.Noise : Some energy also lost in the sound or the noise comes out from the engine. It will consume some energy.
Also, the engine never be 100% efficient some amount of energy lost in environment also.
Answer:
True - Archimedes Principle states that the buoyant force on an object is equal to the weight of the liquid displaced.
C, planets orbit around the sun because of gravity
Answer:
its under the insert table
Explanation:
Answer:
Wavelength, 
Frequency, 
Explanation:
We need to find the intensity of the radiation is a maximum for a black body at 298 K. It can be calculated using Wein's displacement law. It is given by :
Here, T = 298 K
If f is the frequency of black body radiation. It is given by :
Hence, this is the required solution.
