Answer:
a) A skeleton made of hollow bones makes a bird light and helps it to fly
b) The magnet is strongest at its two poles. So the iron pins are attracted to the poles of the magnet.
c) A bulb is said to be fused when both the terminals of the cell and the two terminals of the bulb form a complete loop or path.
d) Electrical switches are covered by plastic as plastic is an insulator and switches are devices used to open and close an electric circuit. The human body is a good conductor of electricity so switches are insulated so that we do not get electric shocks while touching them.
These are the ones I could answer. Hope this helps
Answer:
a) the hollow bones is the lighter bone so if the birds have heavy bones they will attract to the earth because of the earth's gravity so god have given them the hollow bones so that they can fly in the air easily.
b) the iron pins get attracted at the poles of magnet because the poles of the magnet has more power of attraction then middle part of the magnet.
c) a bulb is said to be fused when bulbs filament is broken. bulb glows when the electric circuit passed to the filament if the filament broke then the bulb will not able to glow.
