14 godz. temu · Step 1/6 Identify the electrostatic force between two charges. According to Coulomb's law, the electrostatic force \( F \) between two point charges \( Q \) and \( q \) separated by a distance \( r \) is given by: \[ F = \frac{k Q q}{r^2} \] where \( k \) is Coulomb's constant (\( k \approx 8.99 \times 10^9 \, \text{N m}^2/\text{C}^2 \)).

14 godz. temu · Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity.This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into wind farms and connected to the electrical grid.
