The wire connected to the DC source doesn't emit electromagnetic waves.
The electromagnetic wave is an oscillation of electric fields and magnets field that sustains each other, this wave time has the characteristics that it can travel without a material medium, for which they are of extreme importance.
It is caused by DC sources such as batteries only having a constant voltage, it is different from AC sources which have different voltage over time, AC voltage can induce the wire because AC sources have magnetic flux change. DC sources don't have magnetic flux change so they don't emit electromagnetic waves.

Answer:
This is because helium molecules get bigger when they heat up , so if your balloons keep getting hotter , they will eventually pop
Weight of a person on the earth is given by,
W= mg,
Where, g is the gravitational acceleration of the earth and m is the mass of the person.
Gravitational acceleration of the moon is one-sixth of the earth.
Therefore, the weight of a astronaut who goes to the moon will be one sixth of that on earth. Hence, the astronaut will weight less.
