Option: 4
1.6 cm
Answers (1)
Given values:
Reading at the left end (L) = 5 cm
Reading at the right end (R) = 21 cm
The length of the metal rod (D) can be calculated by subtracting the reading at the left end from the reading at the right end:
D = R - L
Step 1: Calculate the length of the metal rod:
D = 21 cm - 5 cm = 16 cm
The length of the metal rod is 16 cm.
The length of the metal rod is calculated to be 16 cm or 160 mm.
