What is neutral buoyancy
What do you mean by the term neutral buoyancy? Briefly illustrate it.
Expert
Buoyancy is the total upward force experienced by the object submersed in the fluid. Pascal's principle states that fluid pressure on an object rises with depth, thus there is a greater pressure on the bottom of object than the top, resultant in a total upward force. Whenever an object's buoyancy is bigger than its weight, then the object will float.
Biot-Savart law (J.B. Biot, F. Savart) - The law which explains the contributions to the magnetic field by an electric current. This is analogous to the Coulomb's law. Mathematically: dB = (mu0 I)/(4 pi r2) dl cross e
Curie-Weiss law (P. Curie, P.-E. Weiss): A more broad form of Curie's law that states that the susceptibility, khi, of a paramagnetic substance is associated to its thermodynamic temperature T by the equation: Q : Semiconductors and magnetism I need I need well-explained answers on the questions in attached documents

Balmer series (J. Balmer; 1885): An equation that explains the emission spectrum of hydrogen whenever an electron is jumping to the next orbital; four of the lines are in visible spectrum, and the remainder (residue) are in the ultraviolet.
What do you understand by the term Ambient Reflection? And also write down its characteristic?
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
State the law of Lamberts Cosine? Describe briefly?
Reflection law: For a wave-front intersecting a reflecting surface, the angle of incidence is equivalent to the angle of reflection, in the similar plane stated by the ray of incidence and the normal.
Briefly explain the procedure to define the Specific Gravity?
Mach number (E. Mach): It is the ratio of the speed of an object in a specified medium to the speed of sound in that medium.
