If the earth just doubles its size in an instant, the oxygen present in the atmosphere could be much larger. Due to these, we could theorize that insects could grow much larger because the size of their body is heavily dependent on the maximum amount of oxygen present in the atmosphere. Air pressure also increases thus those aerial enthusiasts would enjoy their professions.
All I know is that the more proton and electrons an atom has the less metallic it becomes. But other than that I think it's pretty random
If a 3 Ω and a 1.5 Ω resistor are wired in parallel and the combination is wired in series to a 4 Ω and a 10 V emf device then the current in the 3 Q resistor is 0.667 Ampere
<h3>What is resistance?</h3>
Resistance is the obstruction of electrons in an electrically conducting material.
The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
As given in the problem 3 Ω and a 1.5 Ω resistor are wired in parallel
Their equivalent resistance would be
1/Re= 1/R1 + 1/R2
1/Re = 1/3 +1/1.5
Re= 1 Ω
Now this parallel equivalent is connected with a series combination with a 4Ω resistor
For calculating equivalent resistance in series combination.
R = R1 + R2
R = 1 + 4
R = 5 Ω
As the 10 V emf device is connected then the current flowing can be calculated by using Ohms law
V=IR
10 = 5×I
I = 2 ampere
as the voltage is divided between parallel resistor combination and series resistor
The voltage drop across parallel combination = 10×(1/1+4) volt
= 2 volt
Now the current flows through a 3 Ω resistor by using Ohms law
I = V/R
I= 2/3
I = 0.667 Ampere
Thus, the current flowing through the 3 Ω resistor comes out to be 0.667 Ampere

The ratio of output power to input power is called efficiency. There is no reason that efficiency must be expressed in percent. It can be a fraction a decimal or a ratio.
