Ayúdenme por favor es para mañana un móvil con un movimiento armónico simple tiene una amplitud de 15cm y una frecuencia de 25hz calcular el, la frecuencia angular, la ecuación de velocidad, aceleración, desplazamiento por favor explicación paso a paso

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

Hydrogen and helium are both members of?
