WebJul 28, 2024 · We live in the single moment created at 10⁻43 millionths of a second. In this theory, time does not move in a “tick tock” fashion. In other words, there was just one “tick“, at 10⁻43 second, and no “tock”. That “tick“ is both finite and infinite, existing, in form and structure, as a single moment, but lasting forever. fitssey logowanieWebThe speed at any single instant of time - 14161089. answered The speed at any single instant of time A. speed B.instantanneous speed C.Average speed D.Velocity 2 ... n simple words, the velocity of an object at that instant of time.
