Answer:

In the context of the loop and junction rules for electrical circuits, a junction is where three or more wires are joined.

Explanation:

A point where at least three circuit paths meet i.e wires, is referred to as a junction.

Kirchhoff’s circuit laws are two(2) equations first published by Gustav Kirchhoff in 1845. Fundamentally, they address conservation of energy and charge in the context of electrical circuits. One of the laws known as Kirchoff's Current Law deals with the principle of application of conserved energy in electrical circuits. Kirchoff's Current Law states that the sum of all currents entering a junction must equal the sum of all currents leaving the junction.

This basically means, the algebraic sum of currents in a network of conductors(wires) meeting at a point is equal to zero

A junction is a point where at least three circuit paths meet.

A branch is a path connecting two junctions .

Kirchhoff's circuit laws

This law states that, for any node (junction) in an electrical circuit ,

the sum of currents flowing into that node is equal to the sum of

currents flowing out of that node.

Kirchhoff's circuit laws are two equalities that deal with the current

and potential difference in the lumped

element model of electrical circuits .

Some terms associated with Kirchhoff's circuit laws

resistor : An electric component that transmits

current in direct proportion to the voltage

across it.

electromotive force: (EMF)—The voltage

generated by a battery or by the magnetic force

according to Faraday’s Law. It is measured in

units of volts (not newtons, N; EMF is not a

force).

capacitor : An electronic component consisting

of two conductor plates separated by empty

space (sometimes a dielectric material is

instead sandwiched between the plates), and

capable of storing a certain amount of charge.

pav-90 [236]

As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.

Vector addition of a=8km[E] and b=13km[E]
AlladinOne [14]

The answer to the question is 21 km towards east.

CALCULATION:

Let us consider two vectors \vec A \ and\ \vec B

As per the question, \vec A=8\ km\ towards\ east

                                  \vec B=\ 13\ km\ towards\ east

It is obvious that two vectors are parallel to each other. Hence, the angle between them is zero i.e \theta\ = 0^0

We are asked to calculate the resultant .

As per parallelogram law of vector addition, the magnitude of resultant will be-

                        R=\sqrt{A^{2} +B^{2} +2ABcos\theta}

                              =\sqrt{8^2+13^2+2\times 8\times13 cos0}

                              =\sqrt{64+169+208}    [∵ cos0 = 1]

                              =\sqrt{441}\ km

                              =\ 21\ km

The direction of the resultant will be also towards east as the two vectors are parallel to each other.

Hence, the vector addition of two vectors are 21 km towards east.

A juggler throws a bowling pin straight up in the air. After the pin leaves his hand and while it is in the air, which statement
yuradex [85]

Answer:

The velocity of the pin is opposite its acceleration on the way up.

Explanation:

A juggler throws a bowling pin straight up in the air. After the pin leaves his hand and while it is in the air, the velocity of the pin is opposite its acceleration on the way up.

When an object is thrown straight up in the air, the acceleration due to gravity is acting in the opposite direction. As a result, the velocity of the pin is acting in the opposite direction on the way up.

Hence, the correct option is (d).
