Answer 2

Answer:

I hope it's help you

Explanation:

• Rectilinear propagation of light means =Light travel in straight path
• in electric bulb light is produced to the glowing= The thin filament
• electric current flow only when the circuit= Closed circuit
• which of the following is true of magnet=All of these because

opposite charge attract each other

or magnet has two poles

I hope it's help you give one like plz and brallient answer
