Question

What pressure expressed in pascals equals 70 N/m2?

70 Pa

7000 Pa

700 Pa

7 Pa

Answer 1

Pascals = N/m2
so it is the same unit
the answer is 70 Pa

Answer 2

Option (a) is correct.

70 Pa

Step-by-step explanation:

Pressure is defined as the ratio of thrust acting on the surface per unit area.

If a force of 1 n is acting on a surface of area 1m^2, then we can say the pressure acting on the surface is 1 \frac{N}{m^{2}}[/tex].

The SI unit of pressure is Pa.

`1 Pa = 1 (N)/(m^(2))`

So, It is 70 Pa.
