To solve this problem we will apply the relation of Ohm's law, at the same time we will use the concept of resistance in a cable, resistivity and potential difference.
According to Ohm's law we have to
Here,
V = Voltage
I = Current
R = Resistance
At the same time resistance can be described as
Here,
= Resistivity of the material
l = Length of the specimen
A = Cross-sectional area
From the above expression we can write the current as,
Replacing we have that,
Therefore the current in the wire is 3.809A
<em>Note: The value obtained for the resistivity of Tungsten was theoretically obtained and can be consulted online.</em>
You can thank me if this answer helps. The energy coal comes from energy that was stored in giant plants that lived hundreds of millions of years ago in swamp forests,even before dinosaurs!
It has to gain three more electrons to satisfy the octet rule.
Answer:
The air molecules in the compressions of the second wave are more dense, so the sound is louder.
Explanation:
In a closed room, Noah and Nina are sitting 15 m apart.
As Noah says the same sentence twice, Nina does not hear the sound the first time but she does hear the sentence the second time.
This happens as the air molecules in the compressions of the second wave are more dense. As a result, the sound is louder.
The correct option is ''The air molecules in the compressions of the second wave are more dense, so the sound is louder''
Any metal element can form a positive ion because they lose electrons to become stabilized
