Can electric field lines cross?
Lines of force don't exist. They can't cross each other because they aren't there. The common (related) demonstration of magnetic lines of force using iron filings works because of the fact that the iron filings become little magnets and line up head to tail. If you photograph them and re-run the experiment you will see that the lines are different, which shows that they are an "artifact" of the magnetic field. No actual lines exist.
How do repelling magnetic field lines interact with each other?
When repelling magnetic field lines interact with each other, they push away from each other due to their like charges. This creates a force that causes the field lines to move apart and maintain a distance from each other.
How can you use the field lines to determine whether magnets will attract or repel each other?
You can use the direction of the magnetic field lines to determine if magnets will attract or repel each other. If the field lines are pointing in the same direction between two magnets, they will repel each other. If the field lines are pointing in opposite directions, the magnets will attract each other.
What object must be unique in each schema?
The object that must be unique in each schema is the primary key. The primary key is a unique identifier for each record in a database table, ensuring that each row is uniquely identifiable. This uniqueness helps maintain data integrity and allows for efficient retrieval of specific records.
Do electric field lines cross?
No, electric field lines do not cross each other. If they did, it would imply that there are multiple directions for the electric field at the same point, which is not possible. The electric field lines always repel or attract each other, but they never cross.
What is the field that uniquely identifies each record in a table?
Primary key is the field that uniquely identifies each record in a table. It ensures that each record in a table is unique, and helps to establish relationships between tables in a database.
The field that uniquely identifies a record in a table is called?
The field that uniquely identifies a record in a table is called the primary key. It ensures that each record in a table is distinct and can be easily located and referenced.
In a database a field that uniquely identifies a particular record in a table is called?
In a database, a field that uniquely identifies a particular record in a table is called
What is a number that uniquely identifies each computer or devices connected to the internet?
It is the IP ADDRESS which uniquely identifies any computer conected to internet. It gives the location of the computer also.
What is A field that uniquely identifies a particular record in a table called?
A field that uniquely identifies a particular record in a table is called a primary key. The field or fields on which records are sorted is called the sort key.
Why is a field with an AutoNumber data type a good candidate for the primary key field for that table?
Because it uniquely identifies each record in that table, No two records can have the exact same entry in the field designated as the primary key.
What field identifies each record in a field?
check
What is a field that is chosen to uniquely identify a record called?
A field that is chosen to uniquely identify a record is called a primary key. This key helps uniquely identify each record in a database table and ensure data integrity.
Can a primary key field uniquely identify each record?
Yes it can do that.
Is the primary key a field that uniquely identifies each record?
A unique key is used to enforce uniqueness of each row in a table. A unique key comprises a single column or a set of columns. No two distinct rows in a table can have the same value (or combination of values) in those columns. A primary key is simply a NOT NULL unique constraint. Table can have only one primary key, but many unique keys.
What is an internet address usually beginning with http that uniquely identifies a Web?
url
primary key?
attribute of an entity which uniquely identifies a specific instance of the data
