Two infinite sheets of current flow parallel to the y-z plane. The left-hand sheet, which intersects the x-axis at x = 0, consists of an infinite array of wires parallel to the z-axis with a density n = 910 wires/m and a current per wire of IL = 0.17 A in the +z direction. The right-hand sheet, which intersects the x-axis at x = a = 12 cm, is identical to the left-hand sheet, except that it has a current per wire of IR = 0.17 A in the -z direction.
a) Calculate the y-components of the net magnetic field in the following places: x1 = -15 cm, x2 = 6 cm, and x3 = 24 cm. (The x- and z-components of the B-field are zero.)
B(x1)y = T
B(x2)y = T
B(x3)y = T
b) Suppose the above configuration of currents is unchanged except that the direction of the current IR is reversed so that now IR also flows in the +z direction. (The magnitude remains the same.) Calculate the y-components of the net magnetic field at the same positions as in part a).

If the electrons are to be stacked in circular orbits parallel to the x-z plane with centers on the plane x = a/2, what is the minimum current per wire required if IL and IR are equal in magnitude but opposite in direction?

The Measure of angle E is 55° and Length of the side EF is 12.49 units

The diagram is missing in the question and hence the diagram is shown below!!!

Given the triangle EDF with angle measures ∠D = 43° and ∠F = 82°.

As, we know, The sum of the measures of angles in a triangle is 180°.

So, we have,

∠E + ∠D + ∠F = 180°

i.e. ∠E + 43° + 82° = 180°

i.e. ∠E = 180° - 125°

i.e. ∠E = 55°

Thus, the measure of angle E is 55°.

Further we have

15/sin55 = EF / sin43

∴ EF =  15*sin43/sin55

∴EF = 10.23/0.189

EF = 12.49 units

Hence the length of side of EF is 12.49 units

Answer:

Amount of energy required to change the 1kg of a substance without changing its temperature.

The maximum velocity reached by the person is determined as 11.1 m/s.

The area under the velocity time graph is the total displacement of the person.

Total Area = area of triangle formed during first 2 seconds + area of rectangle during the last 8 seconds

100 = ¹/₂(2v) + v(11 - 2)

where;

100 = v + 8v

100 = 9v

It will cover a distance of 90.155 m.

Explanation:

For the first case, using the kinematic equation 3,

a=9.63 m/s^2

For the second case, u=150 km/h which is 41.67 m/s.

911.4N is the air resistance force acting upward on the falling box.

The constant or the highest speed that an object reaches when it falls through a liquid or gas is referred to as terminal velocity.

At terminal velocity,

The Upward force acting on an object(F) = Weight of the falling object(W).

Due to the fact that the two forces are acting in opposing directions, there is no net force acting on the item, and that's why the speed of the object becomes constant.

The Formula used to calculate the Upward force

F = mg...….. Equation(1)

where,

m = total mass of the box

g = acceleration due to gravity = 9.8 [tex]m/s^{2}[/tex]

F = Air resistance force acting upward on the box

Given:

The box with its contents now has total mass of 93Kg

m = 93 kg

g = 9.8 m/s²

By reading other astronomers' writings and making his own observations, Copernicus established his heliocentrism theory.
