In the figure, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a=8.50 cm. Each wire carries 15.0 A, and all the currents are out of the page. In unit-vector notation, what is the net magnetic force per meter of wire length on wire 1?
The net magnetic force per meter of wire length is ( 7.94 ×[tex]10^{-4}[/tex]N/m)i + ( -7.94 × [tex]10^{-4}[/tex]N/m )j.
Here we have to find the net magnetic force per meter.
Using dB= μi sinФ/ 4π r²dx the force on say, wire 1 (the wire at the upper left of the figure) is along the diagonal (pointing toward wire 3, which is at the lower right). Only the forces (or their components) along the diagonal direction contribute. With θ=45°, we find the force per unit meter on wire 1 to be
F1 =∣ F 12 + F 13 + F 14∣=2F 12 cosθ+F 13=2( μi²/ 2p ia)cos45° + μi² / 2√2πa

= ( 7.94 × [tex]10^{-4}[/tex]N/m) i + ( -7.94 × [tex]10^{-4}[/tex]N/m) j

A subset of vectors in a vector space that are linearly independent and span the entire space is known as a vector basis.
What is basis vector in vector space?
Make V, for some n, a subspace of Rn. If B is linearly independent and spans V, it is said to be a collection of vectors from V with the formula B = v 1, v 2,..., v r. The collection cannot serve as a foundation for V if either of these requirements is not met. Any vector in V can be written as a linear combination of the vectors in a collection of vectors if it spans V and contains enough vectors to do so. Because there aren't too many vectors in the collection, none of them can start to depend on the others if it is linearly independent. Thus, a basis appears to be the perfect size: It can span the room, but it isn't very large.Example 1: Since the vectors I and j are linearly independent and the collection i, j spans R 2, it serves as a basis for R2.

A 22.4 kg block is placed on a ramp that makes an angle of 22 ° to the horizontal. The coefficient of friction between the block and the ramp is 0.11. The block is released from rest and allowed to slide down the ramp. What is the acceleration of the block?
Answer: 2.67 m/s2
Explanation:
W = mg = (22.4 kg)(9.8 m/s2) = 219.52 N
Wx = (219.52 N)(sin 22) = 82.2 N
Wy = (219.52 N) (cos 22) = 203.5 N
Wy = N (normal force on the block) = 203.5 N
Ff (force of friction) = (coeff. friction)(N) = (0.11)(203.5 N) = 22.4 N
Sum the forces in the x-direction (direction of motion down the ramp):
Fnet = Wx - Ff = 82.2 N - 22.4 N = 59.8 N
a = F/m = 59.8 N / 22.4 kg = 2.7 m/s2

___ J
The work that must be done on the hoop to stop it is calculated to be -3.888 J.
As the mass of the hoop is 120 kg and the hoop's center of mass has a speed of 0.180 m/s, the rotational inertia can be given as follows;
I= mr^2
I=120r^2
The kinetic energy of hoop = Linear kinetic energy + Rotational kinetic energy
K= (1/2mv^2) + (1/2Iw^2)
But; w= (v/r)^2
K= (1/2mv^2) + (1/2×120r^2(v/r)^2)
K = (1/2×120×0.180^2) + (1/2×120×0.180^2)
K = 3.888 J
To stop the hoop, its final kinetic energy must be 0, therefore;

If there is resonance at the circuit then impedance will be equal to the resistance of the circuit.
So, Z = R = 15.3 ohm
Io = Eo/Z
= 120/15.3
= 7.84 A
Then ===3 across the inductor will be
VL = Io×XL
= 7.84×793.86
= 6223.8624 V
Hence, the amplitude of the voltage across the inductor at resonance is 6223.8624 V.

a weight of 1.0 kn is suspended from the end of a horizontal strut (of negligible mass) 1.5 m long that projects from a wall. a supporting cable 2.5 m long goes from the end of the strut to a point on the wall 2.0 m above the strut. the tension in the cable is
By observing the tension table we can conclude that the correct answer is Option B ; T = 2 × [tex]10^4[/tex]N
What is tension ?Any physical object that is in contact with another one can apply forces to that object.
Depending on the types of objects in touch, we label these contact forces differently. We refer to the force as tension if a rope, string, chain, or cable is one of the things applying the force.
The best demonstration of a tension force is when a rope is being pulled. The rope builds up a lot of tension when a pull force is applied to it. However, upon pulling on the rope, the tension is lost and the rope becomes slack.
Given mass = 1 kg
N - mg = ma
F = ma
and mg = ma because the object is static
thus N = 2mg
N = 2 × 1000 × 10
N = 2 × [tex]10^4[/tex] N

two particles of masses m1 and m2 ( m1
More than five meters, but less than ten meters, separate two particles with mass m1 and m2 from the atom of mass m1.
Describe mass.In physics, mass is a quantification of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the use of a force. The change caused by a force applied is smaller the more mass a body has.
Describe the mass formula.The mass with one mole of a chemical substance or the ratio of a mass of a chemical to its number of chemicals substance is known as the molar mass (M), which is a physical attribute.

Two large planets may have high gravitational pull between them because the strength of gravity is partially based upon: mass.
Define the Law of gravitation?
Newton's law of gravitation states that-
Any particle of matter in the universe will gravitate toward any other with a force that varies directly as the product of the masses and inversely as the square of the distance between them
It is expressed as-
F = G(m1m2)/R^2
where,
G is the gravitational constant,
m1 and m2 are the masses
R is the distance
More massive objects will pull apart with a stronger gravitational force because the gravitational force is directly proportional to the mass of both interacting objects. Consequently, the gravitational pull between two objects grows as their respective masses do as well. The force of gravity between two things multiplies by 2 if one of their masses doubles. The force of gravity between two objects is tripled if one of their masses is tripled. The force of gravity between two objects is multiplied by two when their masses are equal, and so on.

A rectangular plate is rotating with a constant angular speed about an axis that passes perpendicularly through one corner, as the drawing shows. The centripetal acceleration measured at corner $A$ is $n$ times as great as that measured at corner $B$. What is the ratio $L_{1} / L_{2}$ of the lengths of the sides of the rectangle when $n=2.00 ?$
12.5 m/s² is the centripetal acceleration of rotating body.
speed= 5 m/s
radius= 2 m
centripetal acceleration=v²/r
centripetal acceleration=25/2
centripetal acceleration=12.5 m/s²
The speed at which a body rotates around a circle is known as centripetal acceleration. When a body travels in a circle, its direction is constantly changing, which results in a change in velocity, which generates an acceleration because velocity is a vector quantity (i.e., it contains both a magnitude, the speed, and a direction). The acceleration is directed radially toward the center of the circle. The value of the centripetal acceleration, symbolized by the letter ac, is equal to the square of the body's speed along the curve divided by the circle's radius. This is sometimes referred to as the equation ac = v2/r. Meters per second squared are used to measure centripetal acceleration.
