If the maximum and minimum temperatures at a place on a day are measured as \(44^{\circ} \mathrm{C} \pm 0.5^{\circ} \mathrm{C}\) and \(22^{\circ} \mathrm{C} \pm 0.5^{\circ} \mathrm{C}\) respectively, then the temperature difference is
- A \(22^{\circ} \mathrm{C} \pm 1^{\circ} \mathrm{C}\)
- B \(22^{\circ} \mathrm{C} \pm 0.5^{\circ} \mathrm{C}\)
- C \(22^{\circ} \mathrm{C} \pm 0.25^{\circ} \mathrm{C}\)
- D \(22^{\circ} \mathrm{C} \pm 1.5^{\circ} \mathrm{C}\)
Answer & Solution
Correct Answer
(A) \(22^{\circ} \mathrm{C} \pm 1^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
\(\Delta T = T_{max} - T_{min} = 44^{\circ} \mathrm{C} - 22^{\circ} \mathrm{C} = 22^{\circ} \mathrm{C}\) \(\delta(\Delta T) = \delta T_{max} + \delta T_{min} = 0.5^{\circ} \mathrm{C} + 0.5^{\circ} \mathrm{C} = 1^{\circ} \mathrm{C}\)…
