Answer:
See explaination
Explanation:
CREATE TABLE CATEGORY
(
cid int NOT NULL,
description varchar2(1000),
PRIMARY KEY (cid)
);
CREATE TABLE PRODUCT
(
pid int NOT NULL,
description varchar2(1000),
cid int,
price int,
p_size varchar2(1),
CONSTRAINT chk_price CHECK (price>0),
CONSTRAINT chk_size CHECK (p_size in ('S','M','L')),
CONSTRAINT fk_cid FOREIGN KEY (cid) REFERENCES CATEGORY(cid)
);
Calculate LER for a rectangular wing with a span of 0.225m and a chord of 0.045m. The weight of the glider is 0.0500 Newtons. (Note: the wing span is the width of the wing and is measured from wing tip to wing tip, or perpendicular to the fuselage. The wing chord is the length of the wing measured parallel or along the length of the fuselage.)
Answer:
Area of rectangular wing = span × chord = 0.225×0.045= 0.010125m2
LER = Area/weight = 0.010125/0.0500 = 0.2025
Answer:
B: Hacker
Explanation:
literally anything else aren't even real things besides hacker.
Answer:
Distributed DOS attacks.
Explanation:
Computers in a network or the network itself is are prone to cyber attacks. A cyber attack is a concept of taking advantage of computer network vulnerabilities, to retrieve information from the target source. An example of these types of security attacks is the denial of service (or DOS) attacks.
The DOS or the distributed DOS attack prevents users form accessing or requesting a service that they are legitimately allowed, by flooding the target system with superfluous resource request from millions of computers, controlled by the attacker.
