Fig. 12.10​

Answer 1

Answer:-

No the bulb wouldn't glow.

Explanation:-

The modern eraser is usually a mixture of an abrasive such as fine pumice, a rubbery matrix such as synthetic rubber or vinyl, and other ingredients. The mixture is processed and extruded and, if made with rubber, vulcanized to bond the ingredients.

Meaning:-

1. abrasive:- rough and used for polishing and cleaning
2. vulcanise:- harden rubber by treating it with sulphur at high temperature
