14 godz. temu · Determine the work done \( W \) in moving a charge \( q \) from a distance \( r_1 \) to \( r_2 \) from the charge \( Q \). The work done against the electrostatic force is given by the integral of the force over the distance: \[ W = \int_{r_1}^{r_2} F \, dr \] ... Simplify the expression to get the final formula for the work done: \[ W = k Q q ...

14 godz. temu · An example of a very old age obtained by the co-movement method is the brown dwarf + white dwarf binary COCONUTS-1, with the white dwarf estimated to be 7.3 +2.8 −1.6 billion years old. In this case the mass was not estimated with the derived age, but the co-movement provided an accurate distance estimate, using Gaia parallax.
