14 godz. temu · In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein 's 1905 treatment, the theory is presented as being based on just two postulates: [p 1] [1] [2] The laws of physics are invariant (identical) in all inertial frames of reference ...
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 ...
