target of uri doesn't exist: 'package:firebase core/firebase core.dart'. try creating the file referenced by the uri, or try using a uri for a file that does exist
Answers
The error message "target of uri doesn't exist: 'package:firebase_core/firebase_core.dart'" indicates that the specified file or package is missing in your project. To resolve this issue, you can try creating the missing file or package, or ensure that you are using a correct and existing file reference.
This error message typically occurs in programming when the specified URI (Uniform Resource Identifier) cannot be found or accessed. In this case, the URI 'package:firebase_core/firebase_core.dart' is referring to a file or package named 'firebase_core.dart' within the 'firebase_core' package.
The first step to troubleshoot this issue is to verify if the file or package 'firebase_core.dart' actually exists in your project. Check if you have properly installed the required package, in this case, 'firebase_core', and that the version you are using supports the file you are trying to import.
If the file or package is missing, you need to create it or reinstall the package to ensure it is correctly added to your project. Make sure to follow the installation instructions provided by the package documentation or the official documentation of the framework or library you are using.
If you are confident that the file or package exists, double-check the file reference you are using. Ensure that the URI is correctly formatted and that it matches the actual file path or package name. A small typo or mistake in the file reference can lead to this error.
In summary, the error message "target of uri doesn't exist: 'package:firebase_core/firebase_core.dart'" indicates that the specified file or package is missing. To resolve the issue, create the missing file or package or ensure that you are using the correct and existing file reference.

the designation of zero potential energy as the height of the trampoline
the height of the first jump that the person makes on the trampoline
the velocity of the person as they fall back to the trampoline
the changes that occur in kinetic and potential energy
Answers
The designation of zero potential energy as the height of the trampoline is a boundary condition of the model. It involves the minimum potential energy principle.
The minimum potential energy principle is a key concept in different disciplines, including, among others, physics, thermodynamics and chemistry.
This principle states that a structure will deform and/or will change its position to minimize the total potential energy.
The minimum potential energy principle states that the loss of potential energy is due to its dissipation as heat.

They must have names that are different from the names of any columns used in any SELECT statement within the stored

Answers
They store values that can change as a program executes is not true about variables. Hence option a is correct.
What are variables?Variables are defined as a value that is subject to vary depending on external factors or input to the program. In any programming language, a variable is a designated chunk of computer memory with some data within.
An element cannot be taken away. A amount is represented by a variable. As a result, X is a quantity that is 1. Variables can only be defined once. The variable cannot be declared again once it has been defined. The overall variable costs vary directly as a function of activity level, or the quantity produced.
Thus, they store values that can change as a program executes is not true about variables. Hence option a is correct.

Which of the following characteristics differentiate a rainbow table attack from a brute force attack? (Select two.)
A.
Rainbow table attacks greatly reduce compute cycles at attack time.
B.
Rainbow tables must include precomputed hashes.
C.
Rainbow table attacks do not require access to hashed passwords.
D.
Rainbow table attacks must be performed on the network.
E.
Rainbow table attacks bypass maximum failed login restrictions.
Answers
The two characteristics that differentiate a rainbow table attack from a brute force attack are Rainbow tables must include precomputed hashes and Rainbow table attacks bypass maximum failed login restrictions
B. Rainbow tables must include precomputed hashes: In a rainbow table attack, precomputed hashes are generated and stored in the table for quick lookup. These tables contain a set of precomputed hashes derived from a large number of possible passwords. The attacker compares the hashed passwords in the target system with the precomputed hashes in the rainbow table to find a match. This significantly reduces the compute cycles required during the attack compared to computing hashes on the fly.
E. Rainbow table attacks bypass maximum failed login restrictions: Rainbow table attacks can bypass maximum failed login restrictions because they involve comparing precomputed hashes rather than actually attempting login with different password guesses. This allows the attacker to quickly match the hashed passwords from the target system with the precomputed hashes in the rainbow table without triggering any failed login restrictions.
Therefore, the correct options are B and E.
