Calculate the mass defect and nuclear binding energy of an atom ... To convert to joules per nucleon, simply divide by the number of nucleons.
Grass contains water and sheep need water.
A mixture in which composition is constant throughout the mixture is said to be homogeneous mixture.
Now, oil and vinegar dressing is not considered as a homogeneous mixture because composition is not uniform.
Concrete is made up of three components. Thus, composition is not uniform, so it is not a homogeneous mixture.
A mixture of salt and pepper, when salt is mixed in pepper then the mixture is not uniform as white flecks of salt and black flecks of pepper can be seen in the mixture. Thus, it is not a homogeneous mixture.
Salt water is uniform mixture. Thus, it is a homogeneous mixture.
Thus, salt water is the correct answer.
Explanation:
The given data is as follows.
, 
Area of the flat plate is 2 × 4 = 8 
.
Average convection heat transfer coefficient 
= 
= 
.
Hence, formula to calculate heat transfer through convection from air to the water is given as follows.
q = 
= ![60 W/m^{2} ^{o}C} \times 8 m^{2} \times [(80 - 30)]^{o}C](https://tex.z-dn.net/?f=60%20W%2Fm%5E%7B2%7D%20%5E%7Bo%7DC%7D%20%5Ctimes%208%20m%5E%7B2%7D%20%5Ctimes%20%5B%2880%20-%2030%29%5D%5E%7Bo%7DC)
= 24000 W
or, = 24 kW
Hence, the direction of heat flow is from air to the surface.
Thus, we can conclude that transfer of heat is 24 kW.
D.the concentration of salt in the water her a the coast
