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

the g string on a guitar is 49.0 cm long and has a fundamental frequency of 196.0 hz. a guitarist can play different notes by pushing the string against various frets, which changes the string's length. the fifth fret from the neck gives the musical note c (261.6 hz); the sixth fret gives d-flat (277.2 hz).
The guitar has 6 strings. Listed from low to high, the guitar string notes are: E, A, D, G, B, E.
What are the string and guitar?Guitar string is a string made of a particular material, typically, gut, nylon or steel, which is spanned over a wooden instrument or an instrument which has magnetic or piezoelectric pickups.Many people overlook the importance and vital role of guitar strings. They help your guitar sound, play, and even feel better. Old strings can cause intonation and tuning problems, while new strings can breathe new life into your guitar's sound and playability, keeping your guitar sounding its best.Benefits of String ImmutabilityHence saving memory and fast performance. More secure since we can't change the value of string object. Thread safety while working with strings in a multi-threaded environment. Class loading is more secure since the string value passed as an argument to load a class can't be changed.The distance that should be far apart the third and fourth frets should be Δd = 49.0 cm.
Calculation of the distance that should be far apart:
Since
The G string should be long i.e. 49 cm.
The frequency is 196 Hz
The third fret from the neck gives B is (233.08 Hz)
And, the fourth fret gives B (246.94 Hz).
So here
L3
= Length * frequency / third fret
= 49*196/233.08
= 41.20 cm
L4= Length * frequency / fourth fret
= 49*196/246.94
= 38.888 cm
So here the difference should be
= L3 - L4
= 41.20 cm - 38.888 cm
= 2.3 cm
Hence, distance that should be far apart the third and fourth frets should be Δd = 2.3 cm.

Hunting a black hole. Observations of the light from a certain star indicate that it part of a binary (two-star) system. This visible star has orbital speed v = 270 km/s, orbital period T = 1.70 days, and approximate mass m1==6Ms, where Ms, is the Sun's mass, 1.99×1030 kg Assume that the visible star and its companion star, which is dark and unseen, are both in circular orbits (Fig. 13-47). What integer multiple of Ms, given the approximate mass m2 of the dark star?
The equation has one real solution: α=9.3, which implies m₂ /M s≈9.
What integer multiple of Ms, given the approximate mass m2 of the dark star?The two stars are in circular orbits, not about each other, but about the two-star system's center of mass (denoted as O ), which lies along the line connecting the centers of the two stars. The gravitational force between the stars provides the centripetal force necessary to keep their orbits circular. Thus, for the visible, Newton's second law gives
F=r2Gm₁m₂=r₁m₁v₂
where r is the distance between the centers of the stars. To find the relation between r and r₁, we locate the center of mass relative to m1. Using Equation 9−1, we obtain
r₁=m₁+m₂m₁(0)+m₂r=m₁+m₂m₂r ⇒r=m₂m₁+m₂r₁
On the other hand, since the orbital speed of m₁ is v=2πr₁/T, then r₁=vT/2π and the expression for r can be rewritten as
r=m₂m₁ / m2 × vT/2π
Substituting r and r₁ into the force equation, we obtain
F=(m1+m2)2v2T24π2Gm1m23=T2πm1v
or
6.90×1030kg =3.467Ms
where Ms=1.99×10³⁰kg is the mass of the sun. With m₁=6Ms, we write m₂=αMs and solve the following cubic equation for α:

The distance d from the wire to the center of the loop is 7.64 cm.
What is loop?
A loop is a set of instructions that are repeatedly carried out until a specific condition is met in computer programming. Typically, a specific action is taken, such as getting and changing a piece of data, and then a condition is checked, such as determining whether a counter had also reached a predetermined value. If not, the following instruction in the sequence directs the computer to go back to the first instruction inside the sequence as well as repeat it. The following instruction "falls through" to a following sequential instruction as well as branches outside the loop if the condition has been met. A loop is a fundamental concept in programming that is frequently applied when creating programmes.
The distance d from the wire to the center of the loop is a result of the magnetic field created by the current in the wire. The magnetic field created by a current is proportional to the current and inversely proportional to the distance from the wire. Therefore, we can use the equation B=μI/2πd, where μ is the permeability of free space, B is the magnetic field, I is the current, and d is the distance from the wire to the center of the loop. We can rearrange this equation to solve for d: d= μI/2πB.
Plugging in the given values, we get d= (4π x 10^-7)(20I1)/2π(0) = 7.64 cm. Therefore, the distance d from the wire to the center of the loop is 7.64 cm.

Acceleration is the general term for any process where the velocity changes. There are only two ways to accelerate: either by increasing speed or decreasing direction, or both. The reason for this is that velocity includes both a speed and a direction.
You cannot possibly be accelerating if you don't also change your direction and speed, regardless of how swiftly you are traveling. Because of this, a jet experiences no acceleration even when it is moving at a high speed—in this case, 800 miles per hour—because its velocity is constant.

a diverging lens has a focal length of -27.0 cm. find the image distance when an object is placed 22.0 cm from the lens.
The focal length of a diverging lens is -27.0 cm.
What effect does a diverging lens have on an image?Negative lenses diverge parallel incident light rays and form a virtual image by extending traces of the light rays passing through the lens to a focal point behind the lens. In general, these lenses have at least one concave surface and are thinner in the center than at the edges.
A lens's object distance (u), image distance (v), and focal length (f) all have a relationship.
1/u+1/v=1/f
1/v=1/f-1/u \sv=uf/(u-f) So, if you know the other two variables, you can figure out v.
When the object is at infinity (far from the lens), v=f.

This vehicle control symbol is used to determine ___________________. *
a. low gas levels
b. windshield wipers
c. low oil pressure
d. anti-lock brakes
This vehicle control symbol is used to determine low oil pressure.
A complete vehicle control system involves one ECU, which controls all aspects of the vehicle.
The advantages of central control are predominant into main areas, i.e. inputs and outputs. On the input side consider all the inputs required to operate each of the following three systems.
• Ignition system
• Fuel system
• Transmission system.
One central control system can potentially decrease the complexity of the wiring while increasing the possibilities for control. If each system is operating independently it is possible that each may not react to some extent in the best way with respect to the others.

if the spring is pulled until it stretches 3.00 cm and the pack remains at rest, what is the force of friction exerted on the backpack by the table?
4.5 N is the force of friction exerted on the backpack by the table.
given:
Spring constant speing, k = 150 N/m
Extension spring, x = 3.00 cm = 0.03 m
Force=kx
Force=150×0.03
Force=4.5 N
Friction force is the resistance that forms at the point of contact between two or more objects when they move over one another. The direction of the friction force is always parallel to the motion of the object.
The surface's roughness and external pressures have an impact on how much friction occurs. The rougher the surface, the stronger the force of friction acts on it. The same is true of external elements.
