A vibration magnetometer placed in magnetic merlian has a small bar magnet. The magnet executes oscillations with a time period of 2s in earth’s horizontal magnetic field of 24muT. When a horizontal field of 18muT is produced opposite to the earth’s field by placing a current carrying wire, the new time period of the magnet will be then

The stress-strain curves are drawn for two different materials X and Y. It is observed that the ultimate strength point and the fracture point are close to each other for material X but are far apart for material Y. We can say that material X and Y are likely to be (respectively)
