A) \[\left( 2.94 \pm 0.02 \right)\]
B) \[\left( 2.94 \pm 0.00 \right)\]
C) \[\left( 2.94 \pm 0.04 \right)\]
D) None of these
Correct Answer: C
Solution :
Given length of rod X is \[{{L}_{x}} = 2.25 \pm 0.02\] and length of rod \[{{L}_{y}} =5.19 \pm 0.02\] Rod y is longer, then rod X by length \[\Delta L={{L}_{y}}-{{L}_{x}}\] \[=\,\,\,\left( 5.19 \pm \,\,0.02 \right)-\left( 2.25 \pm \,\,0.02 \right)\] \[=\,\,\left( 2.94 \pm \,\,0.04 \right) cm\]You need to login to perform this action.
