Question

Indicate whether the following statements are True or False. Write T for true and F for false(i) SI units are arbitrary (ii) 1 mm2 = 10–3 m2 (iii) 10–15 g = 1 mpg (iv) SI unit for pressure is Pascal

Answer 1

Answer:

Explanation:

(ii) 1 mm2 = 10–3 m2   FLASE

1 mm² = (1/1000)² m²

=> 1 mm² = 10⁻⁶ m² ≠ 10⁻³ m²

(iii) 10–15 g = 1 mpg   True

10⁻¹⁵ g = 10⁻³ * 10⁻¹²  g

10⁻³ = m  & 10⁻¹² = p

=> 10⁻¹⁵ g = 1 mp

(iv) SI unit for pressure is Pascal - TRUE

The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter

Answer 2

Answer:

si unit are arbitrary true or false
