I say it helped then because TrueType had room
Answer: TRUE
Explanation:
Atoms are happy when they will not react with other elements while having a full outside ring of electrons because this makes them to be noble.
A stable atom possesses full outside ring of electrons while unstable one does not. So, they are happy also because of stability.
Answer:
the translation I got for this question is
Which of the temperature scales is the oldest?
Explanation:
and i searched for it and got this=
Fahrenheit scale
1.
Answer:
Part a)

Part b)

Explanation:
Part a)
Length of the rod is 1.60 m
diameter = 0.550 cm
now if the current in the ammeter is given as

V = 17.0 volts
now we will have


R = 0.91 ohm
now we know that



Part b)
Now at higher temperature we have


R = 0.98 ohm
now we know that



so we will have



2.
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that current density is defined as

now we have

Now we have


so we will have

Part b)
now we have

so we have


so we have


To solve this problem it is necessary to take into account the concepts of Intensity as a function of Power and the definition of magnetic field.
The intensity depending on the power is defined as

Where
P = Power
r = Radius
Replacing the values that we have,


The definition of intensity tells us that,

Where,
Magnetic field
Permeability constant
c = Speed velocity
Then replacing with our values we have,

Re-arrange to find the magnetic Field B_0

Therefore the amplitude of the magnetic field of this light is
