A portable speaker is switched on. 600 J of energy is transferred from the chemical
store in the battery to the thermal store of surroundings; 250 J by heating and
some by radiation (sound). How much energy is transferred by radiation?​


Sagot :

Answer:

350 J of energy is transferred by radiation.

Explanation:

Given that,

600 J of energy is transferred from the chemical  store in the battery to the thermal store of surroundings.

Heat energy = 250 J

Sound energy = x

According to the conservation of energy,

600 = 250 +x

x = 600-250

x = 350 J

So, 350 J of energy is transferred by radiation.
