b) what is unit of pressure?
c) what is SI unit of force?​

Answer 1

Answer:

si unit of pressure is Pascal and force ka si unit Newtown

Answer 2

Answer:

1. The SI unit for pressure is the Pascal (PA) , equal to one newton per square metre (N/m2, or kg·m−1·s−2).

2.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.

3. The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.
