Which of the following phenomena can be attributed to mechanical, electrical, magnetic, thermal, sound

Which of the following phenomena can be attributed to mechanical, electrical, magnetic, thermal, sound, light: a) a cup falls from the table and breaks; b) The ambulance gives a signal; c) snow melts outside in spring; d) a plastic ruler worn on a woolen cloth attracts pieces of paper; e) a magnetized screwdriver attracts nails; f) during the rain, thunder is heard and lightning flashes are visible?

a) A cup falls from the table and this mechanical phenomenon breaks. Changing the position of the body relative to other bodies.
b) An ambulance car gives a signal – a sound phenomenon based on mechanical vibrations of particles of a substance. The signal membrane sets in motion the air molecules, which transmit these vibrations to the eardrum of the ear.
c) Snow melts on the street in spring – this is a thermal phenomenon. Changes in the properties of the body with a change in temperature.
d) A plastic ruler rubbed against a woolen cloth attracts pieces of paper – an electrical phenomenon. There is a redistribution of electric charge, electrification of the body through friction.
e) A magnetized screwdriver attracts nails to itself this magnetic phenomenon.
f) During the rain, thunder rolls are heard and lightning flashes are visible – an electrical, sound, optical phenomenon. An electrical discharge occurs, accompanied by a flash of light and sound thunder.
