Question

answer the following​

Answer 1

Answer:

A.) The image formed by pinhole camera is inverted.

B.) when we heat a magnet at high temperature it loses its magnetic power

Answer 2

1. The image formed in a pinhole camera is real, inverted, and small.

2.If a magnet is exposed to high temperatures, the delicate balance between temperature and magnetic domains is destabilized. At around 80 °C, a magnet will lose its magnetism and it will become demagnetized permanently if exposed to this temperature for a period, or if heated above their Curie temperature.
