Bernoulli's principle can be derived directly from Newton's second law or Conservation of Energy.

The correct answer should be 1st law of thermodynamics.

It should be first law of thermodynamics since it is based on energy conservation and 1 st law says energy can neither be created nor be destroyed, it is conserved.

Answer should be A.

The answer should be A & C. Because Bernoulli's equations is derived from the either 'conservation of momentum or Energy principle.

Option A should be correct.

Yes, Option A is correct.

It's based on energy conversation so answer A is correct.

First law of thermodynamics is the conservation of energy, which states that energy can neither be created nor destroyed. Energy can only be transformed. Principle of conservation of energy is the basis of Bernoulli's equation.

The first law of thermodynamics is the law of conservation of energy, which states that the total energy of a system and its surroundings is constant. Bernoulli’s equation is derived from the conservation of mechanical energy, which is a special case of the first law of thermodynamics that applies to ideal fluids with no heat transfer or friction. However, Bernoulli’s equation does not account for the internal energy or the heat transfer of the fluid, which are also part of the first law of thermodynamics. Therefore, Bernoulli’s equation is not dependent on the first law of thermodynamics.
