Sometimes on the beach I find clam shells and sometimes snail shells with a perfectly round hole in them, a few millimeters in diameter. It looks like it was made by some kind of animal. A friend said this is from starfishes. Is that correct?

You are in a dark room. There is a table on which there are 50 coins (18 heads and 32 tails). There is no way you can tell (by seeing, touching etc.,) whether a coin is head or tail.

You have to somehow seperate the coins in to 2 groups so that each group has same number of heads. You can flip any coins you want.

Connection wires to a electric heater doesn't get hot, when the heater coil is hot. why?

Lets think about a nicrome coil (of course small in length) connected to a lead acid battery via an uninsulated copper wire (of the same diameter as the nicrome coil)

Condition 1: Battery is switched off :- Now the nicrome wire is heated by a candle flame, as a result the coil heats up, and the connection wire (i.e. copper wire) also gets heated up in this case.

Condition 2: Now the battery is turned on and the coil gets heated ( in fact red hot), but this time the copper wire does not get much heated.Why?
I hope this has to do something with the flow of electrons
