Answer 2

human Heart can be considered as an unbuilt clock as it beats at regular intervals under normal conditions just like a clock

3.262 light years

A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km.

The torr (symbol: Torr) is a unit of pressure based on an absolute scale, now defined as exactly 1760 of a standard atmosphere (101.325 kPa). Thus one torr is exactly101325760 pascals (≈ 133.32 Pa). Historically, one torr was intended to be the same as one "millimeter of mercury
