The magnitude of the circuit current is 0.20 A. The value of the current in the circuit is found with the help of the ohm's law.

Ohm's law claims that the voltage across a conductor is directly proportional to the current flowing through it.

All the resistance combined in the series so that the equivalent resistance is;

[tex]\rm R_{eq}= R_1+R_2+R_3 \\\\ R_{eq}=15+21+24 \\\\ R_{eq}=60 \ ohm[/tex]

This current-voltage connection may be expressed mathematically by the Ohm's Law;

V=IR

[tex]\rm I_{total} = \frac{V}{R_{total}} \\\\ \rm I_{total} = \frac{12}{60} \\\\ I_{total} = 0.20 \ A[/tex]

Hence, the magnitude of the circuit current is 0.20 A.

Cesium has 37 isotopes. One of Cesium's most stable isotopes undergoes beta decay to form Barium-135. 135 Cs 55 is the correct isotopic notation for the original Cesium isotope before it decayed.

Beta decay is a radioactive decay in which a proton is converted into a neutron or vice versa inside the nucleus of the radioactive sample.

In beta decay, an electron is ejected which increases the atomic number.

135Cs55 ⇒135Ba56  + 0e-1

Cesium      Barium      beta particle

Thus, 135 Cs 55 is the correct isotopic notation for the original Cesium isotope before it decayed.

An increase in area of a solid when heated is called area or superficial expansivity.

The charge on the particle when the 4000 v equipotential surface is 26. 0 cm farther from a positively charged particle than the 5000 v equipotential surface is 2.89×10⁻⁵ nC.

The point charge can be found using the following expression.

[tex]q=\dfrac{Vr}{K}[/tex]

Here, V is the potential of a point charge, r is the distance and K is the coulombs constant.

This equation can also be given as,

[tex]r=K\dfrac{q}{V}[/tex]

The 4000 V equipotential surface is 26.0 cm farther from a positively charged particle than the 5000 v equipotential surface. For this case, the distance at both point is,

[tex]r_1=K\dfrac{q}{V_1}\\r_2=K\dfrac{q}{V_2}[/tex]

Subtract both the distance which is equal to 26 cm.

[tex]r_1-r_2=K\dfrac{q}{V_1}-K\dfrac{q}{V_2}\\26=Kq(\dfrac{1}{V_1}-\dfrac{1}{V_2})\\26=(9\times10^9)q(\dfrac{1}{4000}-\dfrac{1}{5000})\\q=2.89\times10^{-14}\rm\; C\\q=2.89\times10^{-5}\rm\; nC[/tex]

The equivalent capacitance of the combination is  [tex]\dfrac{1}{C} = \dfrac{1}{C_1}+\dfrac{1}{C_2}[/tex]  where C1 and C2 are the capacitance of both capacitors in series.

Let the capacitance of both capacitors be C1 and C2. For a series connected capacitors, same charge flows through the capacitors but different voltage flows through them.

Let Q be the amount of charge in each capacitors,

V be the voltage across each capacitors

C be the capacitance of the capacitor.

Using the formula Q = CV where V = Q/C... (1)

For the large capacitor with capacitance of the capacitor C1,

[tex]Q = C_1V_1;[/tex]

[tex]V_1 = \dfrac{Q}{C_1}...(2)[/tex]

where [tex]V_1[/tex] is the voltage across [tex]C_1,[/tex]

For the small capacitor with capacitance of the capacitor [tex]C_2[/tex],

[tex]Q = C_2V_2[/tex];

[tex]V_2 = \dfrac{Q}{C_2} ... (3)[/tex]

where [tex]V_2[/tex] is the voltage across [tex]C_2[/tex],

Total voltage V in the circuit will be;

[tex]V = V_1+V_2... (4)[/tex]

Substituting equation 1, 2 and 3 in equation 4, we have;

[tex]\dfrac{Q}{C} = \dfrac{Q}{C_1} +\dfrac{ Q}{C_2}[/tex]

[tex]\dfrac{Q}{C} = Q({\dfrac{1}{C_1}+\dfrac{1}{C_2})[/tex]

Since change Q is the same for both capacitors since they are in series, they will cancel out to finally have;

[tex]\dfrac{1}{C} = ({\dfrac{1}{C_1}+\dfrac{1}{C_2})[/tex]

This gives the equivalent capacitance of the combination.

Fluorine different from chlorine, bromine, and iodine,because it is the most electronegative and reactive element in the periodic table.

The periodic table is an organization of all known elements in order of increasing atomic number and repeating chemical characteristics.

They are organized in a tabular format, with a row representing an era and a column representing a group.

Elements are ordered in increasing atomic number order from left to right and top to bottom.

Elements of the same group will have the same valence electron configuration and, as a result, will have comparable chemical characteristics.

Elements in the same period, on the other hand, will have an increasing order of valence electrons. Fluorine,chlorine, bromine, and iodine are halogens.

Hence,fluorine different from chlorine, bromine, and iodine because it is the most electronegative and reactive element in the periodic table.
