How long the period of the earth's circulation (365 1/4) in seconds?
Answers
Answer:
31,556,736 seconds
Explanation:
The period of Earth's orbit around the Sun, T = (365 + 1/4) days (three hundred and sixty five and a quarter days
The period of Earth's orbit around the Sun in seconds is given by converting, T = into seconds as follows;
There are 60 seconds per minute, 60 minutes in each hour, 24 hours within each day, therefore, we get;
T = ×60 sec/min × 60 min/hr. × 24hr/day = 31,556,736 seconds

Final answer:
The sum of two vectors A and B is a resultant vector R, where R = A + B. If vectors A and B are plotted with their tails at the origin and heads at points (x1, y1) and (x2, y2), respectively, the resultant vector R ends at point (x1+x2, y1+y2). This represents the sum of the individual components of vectors A and B.
Explanation:
In vector addition, the equation for the sum of two vectors A and B can be generally represented as R = A + B, where R is the resultant vector. If the vectors are plotted with their tails at the origin and their heads ending at points (x1, y1) for Vector A and (x2, y2) for Vector B, the resultant vector, R, will end at the point (x1+x2, y1+y2). In other words, the components of the resultant vector are simply the sum of the components of the original vectors.

the range or the ball is 48.81 m
Explanation:
given;
Nicole throws a ball at 25 m/s at an angle of 60 degrees abound the horizontal.
find:
What is the range of the ball?
solution:
let Ф = 25°
Vo = 25 m/s
consider x-motion using time of fight: x = Vox * t
where x = R = range
t = 2 Voy
g
R = Vo² sin (2Ф)
g
plugin values into the formula:
R = (25)² sin (2*25)
9.81
R = 48.81 m
therefore, the range or the ball is 48.81 m

Answer:
The purpose of a core in an electromagnet is to enhance the magnetic field strength produced by the electromagnet. The core is typically made of a ferromagnetic material, such as iron or steel, that can easily magnetize and demagnetize.
When an electric current flows through a wire wrapped around the core, a magnetic field is generated. This magnetic field is concentrated and strengthened by the core material. The core acts as a pathway for the magnetic field lines to flow through, making the electromagnet stronger and more efficient.
The core helps to increase the magnetic flux density, which is the amount of magnetic field passing through a given area. By concentrating the magnetic field, the core allows the electromagnet to exert a stronger force on nearby magnetic objects, such as attracting or repelling other magnets or moving metal objects.
To visualize this, think of the core as a "magnetic conductor" that channels and focuses the magnetic field. It's like using a magnifying glass to concentrate sunlight onto a small spot, making it hotter and more intense. Similarly, the core enhances the strength of the magnetic field produced by the electromagnet.
In summary, the purpose of a core in an electromagnet is to increase the magnetic field strength by providing a pathway for the magnetic field lines to flow through. This makes the electromagnet more powerful and allows it to perform various tasks, such as lifting objects, generating electricity, or controlling mechanical devices.

Answer:
Purpose of a core in an electromagnet to increase the strength, efficiency, and size of the magnetic field.
Explanation:
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil.
The purpose of a core in an electromagnet is to concentrate the magnetic field.
The coil of wire that creates the magnetic field in an electromagnet is typically made of copper, which has a relatively low magnetic permeability. This means that the magnetic field lines tend to spread out in all directions, resulting in a weak magnetic field.
Some of the purposes of using a core in an electromagnet are:
- To increased magnetic field strength:
The core concentrates the magnetic field, resulting in a much stronger magnetic field. - To reduced size:
The core helps to confine the magnetic field, which can reduce the size of the electromagnet. - To improved efficiency:
The core helps to direct the magnetic field, which can improve the efficiency of the electromagnet.
Overall, the core in an electromagnet plays an important role in increasing the strength, efficiency, and size of the magnetic field.
