During which time interval does the object travel approximately 10 meters

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Apiece of metal with a length of 1.42 cm was measured using four different instruments. which of the following measurements is the most accurate?
