6. Why are board-pins made sharp?7. Define pressure and its SI unit. |

Answer» 6.Board pins are MADE SHARP as they can easily penetrate the surface of the soft board so, that PRESSURE is maximum.7.Pressure—the effect of a force applied to a surface—is a derived unit, obtained from combining base units. The unit of pressure in the SI system is the pascal (PA), defined as a force of one Newton per square meter. The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr.hope this will help you................................. and don't forget to mark me as BRAINLIEST have a nice day. |
