Hi everyone! I have a question about mathematical methods in physics. The question is Turkish in attached but I translated it for you. Can you help me please? Thx a lot.
(a) Show that the function ω satisfies the condition ∇⃗ u ∙ ∇⃗ v = 0 so that the function is analytical (where ∇⃗ is the del operator and it is defined as ∇⃗ ∶ = î × ∂ / ∂x + î × ∂ / ∂y. U = î × ∂u / ∂x + î × ∂u / ∂y. Similarly, ∇⃗ v is defined.)
(b) Show that the function ω must be analytical to be a harmonic function, that is, it must satisfy the Cauchy-Riemann conditions. (Hint: If a function u (x, y) is harmonic, it satisfies the following condition: ∇ ^ 2u = ∂ ^ 2u / ∂x ^ 2 + ∂ ^ 2u / ∂y ^ 2 = 0. In this case, u and v must meet the harmonics condition separately.)

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
