Answer:
Kinetic energy
Explanation:
When an apple falls from a tree it has to do with the energy from gravity. Gravity energy turns into kinetic energy once its in motion.
Sorry if im wrong
2ω is the resistance of the second wire if the resistance of the first is 4ω if two wires have the same length, but the second has twice the diameter of the first.
R= 4ω.
R = ρl/A
2d=r
R2=2ω
Resistance is the capacity of a conductor to obstruct the passage of an electric current through it. It is controlled by the interaction of the applied voltage and the electric current passing through it.
Conductors have very little resistance, whereas insulators have a significant amount of resistance. The resistance increases as the current flow decreases. Resistance is influenced by the properties and dimensions of the material (area of cross section)

This element have 10 neutrons
Answer:
<em>6.02 dB increase </em>
<em></em>
Explanation:
Let us take the initial power from the speaker P' = P Watt
then, the final power P = 4P Watt
for a given unit area, initial intensity (power per unit area) will be
I' = P Watt/m^2
and the final quadrupled sound will produce a sound intensity of
I = 4P Watt/m^2
Increase in loudness is gotten from the relation
ΔL = 
where
I = final sound intensity
I' = initial sound intensity
imputing values of the intensity into the equation, we have
==> 
= 
= <em>6.02 dB increase </em>
