ANSWER ASAP PLS Finn drew a diagram to compare Einstein’s two postulates of relativity. A venn diagram with 2 intersecting circl
es. The circle on the left is labeled first postulate and the circle on the right is labeled second postulate. There is an X in the first postulate circle, a Z in the second postulate circle and a Y in the intersecting area. Which labels belong in the areas marked X, Y, and Z? X: applies to objects moving almost at the speed of light Y: describes the effect of constant motion in space on time Z: speed of light is always 3.0 × 108 m/s X: speed of light is always 3.0 × 108 m/s Y: applies to objects moving almost at the speed of light Z: describes the effect of constant motion in space on time X: speed of light through empty space is the same for all observers Y: laws of physics are the same for all uniformly moving frames of motion Z: applies to objects with constant velocity X: laws of physics are the same for all uniformly moving frames of motion Y: applies to objects with constant velocity Z: speed of light through empty space is the same for all observers
Let the charges be q and Q separated by a distance r. The electrostatic force , F = kqQ/r² = 72 units. If q = 2q and Q = 3Q, then the new electrostatic force is
