The force on one of the wires is determined as 1.76 x 10⁻⁴ N/m.
Force on the wire
The force between the two parallel wire is calculated as follows;
F = μI²L/2πr
where;
I is the current in the two wiresL is length of the wiresr is the distance between the wiresF = (4π x 10⁻⁷ x 6.5² x 1.5)/(2π x 0.048)
F = 2.64 x 10⁻⁴ N
Force per unit length of the wireF/L = 2.64 x 10⁻⁴ N / 1.5
F/L = 1.76 x 10⁻⁴ N/m
Thus, the force on one of the wires is determined as 1.76 x 10⁻⁴ N/m.

As elements gain more electrons in their outer shells, their electrical
conductivity generally decreases. Which of the following explains this
phenomenon?
Answers
Electrical conductivity often decreases, when elements receive additional electrons in their outer shells. As a result of the valence shell being filled, the number of movable electrons decreases.
What is a mobile electron?Electrons are mobile charges in the conduction band while holes are mobile charges in the valence band.
Current flow in a semiconductor is caused by charge carrier migration in both the conduction and valence bands.
Which creates a net motion of positively charged carriers in the same direction as the field and negatively charged carriers in the opposite direction as a result of the force.
The outermost electrons in metals are not bonded to each atom which is shared by many atoms. This decentralization is what allows metals to conduct electric currents.
Hence, the elements gain more electrons in their outer shells, and their electrical conductivity generally decreases.

Explanation: ckeck this imageThree sticks are arranged to form a right triangle. If the lengths of the three sticks are 0.47 m, 0.62 m and 0.78 m, what are the three angles of the triangle?
Answers
The angles in the triangle are 91 degrees, 53 degrees and 36 degrees respectively.
What is the cosine rule?From the cosine rule we know that;
c^2 = a^2 + b^2 - 2abcosC
Since;
a = 0.47 m
b = 0.62 m
c = 0.78 m
Then;
(0.78)^2 = (0.47)^2 + (0.62)^2 - 2(0.47 * 0.62)cosC
0.61 = 0.22 + 0.38 - 0.58 cosC
0.61 - ( 0.22 + 0.38) = - 0.58 cosC
0.01 = - 0.58 cosC
C = cos-1(0.01/-0.58)
C = 91 degrees
Using the sine rule;
b/Sin B = c/Sin C
0.62/sinB = 0.78/sin 91
0.62/Sin B = 0.78
B = sin-1 (0.62//0.78)
B = 53 degrees
Angle A is obtained from the sum of angles in a triangle;

Specific heat of water = 1 kcal /kg deg C
Heat gain = 1.33 * 80 + (12.4 + 1.33) T = 106 + 13.7 T
Heat Loss = 12.4 * (20 - T) = 248 - 12.4 ΔT
