The answer is 761.4 A/cm^2.
To calculate the corresponding current density in the 16-gauge copper wire, we need to determine the cross-sectional area of the wire and divide the maximum current by this area. Here are the steps:
1. Calculate the radius of the wire:
Radius = (0.129 cm) / 2 = 0.0645 cm
2. Convert the radius to meters:
Radius = 0.0645 cm = 0.000645 m
3. Calculate the cross-sectional area of the wire using the formula for the area of a circle:
Area = π * (radius)^2 = π * (0.000645 m)^2
4. Calculate the maximum current density by dividing the maximum current by the cross-sectional area:
Current Density = Maximum Current / Area
Given:
Maximum Current = 10 A
By substituting the values into the equation, we can calculate the current density:
Current Density = 10 A / (π * (0.000645 m)^2)
By evaluating this expression, you can determine the corresponding current density in the 16-gauge copper wire.
The cross-sectional area of a wire with diameter d is given by:
A = πd^2/4
For a 16-gauge copper wire, the diameter is 0.129 cm. Thus, the cross-sectional area is:
A = π(0.129 cm)^2/4 = 0.01315 cm^2
The maximum current of 10 A corresponds to a current density of:
J = I/A = 10 A/0.01315 cm^2 = 761.4 A/cm^2
Therefore, the corresponding current density is 761.4 A/cm^2.

C.
a precursor for developing a disorder, but not a disorder on its own
Answer:
B) caused by eating irregularly over short periods
Explanation:
Disordered eating refers to a range of irregular and unhealthy eating behaviors and attitudes toward food. Disordered eating is often C. a precursor for developing a disorder, but not a disorder on its own
Disordered eating refers to a range of irregular eating behaviors and attitudes towards food that may not meet the full diagnostic criteria for an eating disorder but still involve disturbances in eating patterns, body image, and weight. It can include behaviors such as restrictive eating, binge eating, purging, or excessive exercise.
While disordered eating shares similarities with eating disorders, it is considered a precursor or warning sign that someone may be at risk of developing a diagnosable eating disorder, such as anorexia nervosa, bulimia nervosa, or binge eating disorder. Disordered eating patterns can often progress and become more severe if left untreated, potentially leading to the development of an eating disorder.

Explanation:
When the comet passes close to the sun, it has a visible tail. Typically, the comet is only visible for a matter of days while it may be invisible for years. Why does the comet spend so little time close to the sun?
Answer:
The comet is locked in the Sun's gravity. as it falls deeper in the gravity we'll, its velocity increases. As is travels closer to the Sun, it is trying to break away, but cannot. This transforms into a sideways movement that produces a tight turn. It races further out of the gravity well, and sheds velocity.

A bus negotiates a curve of radius 487 m. What force will be exerted on an 80 kg passenger by the outside wall of the bus when it is traveling at 60 km/h?
Answer:
Centrifugal Force = 45.65N
Explanation:
Given the following data;
Mass, m = 80kg
Radius = 487m
Velocity = 60km/h to m/s = 60*1000/3600 = 16.67m/s
To find the centrifugal force;
Centrifugal Force = mv²/r
Substituting into the equation, we have;
Centrifugal Force = 80*16.67²/487
Centrifugal Force = 80*277.89/487
Centrifugal Force = 2223.12/487
Centrifugal Force = 45.65N

A box of books weighing 315 N is shoved across the floor by a force of 477 N exerted downward at an angle of 35° below the horizontal. If the coefficient of kinetic friction between the box and the floor is 0.58, how long does it take to move the box 4.20 m starting from rest?
Answer:
It takes 1.14 s to move the box 4.20 m.
Explanation:
Using Newton's second law we have:
[tex]Fcos(35)-F_{f}=ma[/tex]
[tex]Fcos(35)-\mu mg=ma[/tex]
F is the force exerted and m the mass of the books
[tex]Fcos(35)-\mu mg=ma[/tex]
[tex]477cos(35)-(0.58*315)=\frac{315}{9.81}a[/tex]
So, the books accelerate at:
[tex]a=6.48\: m/s^{2}[/tex]
We know that the initial velocity is zero, so using the kinematic position equation, we have:
[tex]x=\frac{1}{2}at^{2}[/tex]
So, we just need to solve the equation for t.
[tex]4.2=\frac{1}{2}6.48t^{2}[/tex]
[tex]t=\sqrt{\frac{2*4.2}{6.48}}[/tex]
Taking the positive value of t:
[tex]t=1.14\: s[/tex]
Therefore, it takes 1.14 s to move the box 4.20 m.

Alli was in the park playing on the equipment. she noticed that on the highest slide she slides down
Explanation:
veiebrlrkorvziveieviebelebenduvrvr
Alli was in the park playing on the equipment. She noticed that on the highest slide, she slides down with the greatest speed. The correct option is C.
What is the relation between height and speed?Height is the measurement of someone or something from head to foot or from base to top.
The curved slide is the fastest, despite being longer than the other circuits. This is due to the fact that it is steeper at first, leading the ball to be more affected by gravity and accelerate more quickly before reaching its top speed.
When two items rub against one another, as a slide and a person's bottom, friction is created. A slide would accelerate the rider too quickly without friction, possibly injuring them. Various substances known as lubricants can lessen the impact of friction.
Therefore, the correct option is C) With the greatest speed.

The greater the mass of an object.
Answer:
Mass is the measure of an object's matter (what it's made up of). The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system.

A person records a bird call as an analog wave. The sound is then stored on a computer as a digital signal. When a person wants to listen to the bird call, it needs to be converted back into an analog wave. What is an advantage of storing the bird call as a digital?
Answer:
In analog technology, a wave is recorded or used in its original form. In digital technology, the analog wave is sampled at some interval, and then turned into numbers that are stored in the digital device. On a CD, the sampling rate is 44,000 samples per second. An analog recording is considered unlimited. Therefore, it can move to a higher and higher resolution without losing its original quality.

Look at the equation below. What units are used for W? Give the full name, not the symbol.
Enter your answer
W = m x g
Answer:
the watt is a unit of power
The symbol W denotes the work done and m is the mass and g is the acceleration due to gravity. If m is in Kg and g has a unit of m/s². Then the unit Kg m/s² is equal to one joule J. That is the unit of work done.
What is work done?Work done in physics is the dot product of force and displacement. Work done of one joule is equal to the force of one newton, exerted by an object of mass m and acceleration a.
Thus we have F = Ma.
If the acceleration is replaced by acceleration due to gravity g, then force of one Newton is mg, that is the product of mass and acceleration. Force is an external agent act on a body to change its state from rest or motion.
If the force applied causes a displacement of the object, then a work is done on the body. Let the mass is taken in Kg and acceleration due to gravity is in m/s², then one newton is Kg m/s² is equal to one joule J. Hence, W has the unit of Kg m/s² or J.

An 12 kg object accelerating from 9 m/s to 14 m/s. What is the change in momentum of the object?
Answer:
Change in momentum = 60kgm/s.
Explanation:
Given the following data;
Mass, m = 12kg
Initial velocity, u = 9m/s
Final velocity, v = 14m/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
To find the change in momentum;
Mathematically, change in momentum is given by the formula
[tex] Change \; in \; momentum = m(v - u) [/tex]
Substituting into the equation, we have;
[tex] Change \; in \; momentum = 12(14 - 9) [/tex]
[tex] Change \; in \; momentum = 12*5[/tex]
Change in momentum = 60kgm/s.
