prob 22 pic.png Determine the direction’ measured counter-clockwise from the positive x-direction’ of the acceleration for m = 2.0 kg, F1 = 32.0 N, F2 = 18.0 N, F3 = 22.0 N, θ1 = 37.00, and θ2 = 25.00.

Which of the following conditions must be met for a relation to be in First Normal Form (1NF)?

Consider the following table definition:   CREATE TABLE Employees (    emp_id INT PRIMARY KEY,    email VARCHAR(255) UNIQUE,    name VARCHAR(255));   What is the key difference between the PRIMARY KEY constraint on emp_id and the UNIQUE constraint on email?

What is the primary purpose of creating an index on a database table?  

Consider the relation Sells (bar, beer, price) And suppose we added this tuple-based check   CHECK (bar = ‘Joe”s Bar’ OR price

Consider two tables, Sells and Beers, with the following schema:   CREATE TABLE Beers (    name VARCHAR(50) PRIMARY KEY,    manf VARCHAR(50));   CREATE TABLE Sells (    bar VARCHAR(50),    beer VARCHAR(50),    price DECIMAL(5,2),    FOREIGN KEY (beer) REFERENCES Beers(name));   What happens if the following INSERT statement is executed? INSERT INTO Beers(name, manf) VALUES (‘Bud Light’, ‘Anheuser’);  

Consider the relation Sells (bar, beer, price) and the following view that has been created: CREATE VIEW ExpensiveBeers AS SELECT DISTINCT beer, price FROM Sells WHERE price > 5.00;   What happens when you attempt to update the ExpensiveBeers view?
