Question

The distance x determined by the difference between two separate position measurements are x₁ = 10.5 + 0.1 cm and x₂ = 26.8 + 0.1 cm. Then x will be recorded as: (A) 16.3 cm (B) 16.3 + 0.1 cm (C) 16.3 + 0.2 cm (D) 16.3 + 0.01 cm

Answer 1

Answer: A

Step-by-step explanation:

The distance x determined by the difference between two separate position measurements, x₁ and x₂, is given by:

x = x₂ - x₁

Substituting the given values:

x = (26.8 + 0.1 cm) - (10.5 + 0.1 cm)

Now, calculate the difference:

x = (26.8 - 10.5) cm + (0.1 cm - 0.1 cm)

x = 16.3 cm + 0 cm

So, the distance x is recorded as 16.3 cm.
