- Alength of the wire: $30\,\text{cm}$ ruler; diameter of the wire: micrometer
- Blength of the wire: half-metre rule; diameter of the wire: $30\,\text{cm}$ ruler
- Clength of the wire: half-metre rule; diameter of the wire: micrometer
- Dlength of the wire: micrometer; diameter of the wire: half-metre rule
