We’ve all heard about them, and we all have our fears. For everyday Internet users, computer viruses are one of the most common threats to cyber security. Statistics show that approximately 33% of household computers are affected with some type of malware, more than half of which are viruses.
2. Rogue security software
Rogue security software is malicious software that mislead users to believe there is a computer virus installed on their computer or that their security measures are not up to date. Then they offer to install or update users’ security settings. They’ll either ask you to download their program to remove the alleged viruses, or to pay for a tool. Both cases lead to actual malware being installed on your computer.
3. Trojan horseMetaphorically, a “Trojan horse” refers to tricking someone into inviting an attacker into a securely protected area. In computing, it holds a very similar meaning — a Trojan horse, or “Trojan,” is a malicious bit of attacking code or software that tricks users into running it willingly, by hiding behind a legitimate program.
4. Adware and spyware
By “adware” we consider any software that is designed to track data of your browsing habits and, based on that, show you advertisements and pop-ups. Adware collects data with your consent — and is even a legitimate source of income for companies that allow users to try their software for free, but with advertisements showing while using the software. The adware clause is often hidden in related User Agreement docs, but it can be checked by carefully reading anything you accept while installing software. The presence of adware on your computer is noticeable only in those pop-ups, and sometimes it can slow down your computer’s processor and internet connection speed.
5. Computer worm
Computer worms are pieces of malware programs that replicate quickly and spread from one computer to another. A worm spreads from an infected computer by sending itself to all of the computer’s contacts, then immediately to the contacts of the other computers.
A watermelon is thrown off of a roof to the ground. Its momentum changed from 50kgm/s to 2kgm/s. What is the impulse?
Answer:
Impulse of watermelon = -48 kg-m/s
Explanation:
Given:
Final momentum of water melon = 2 kg-m/s
Initial momentum of water melon = 50 kg-m/s
Find:
Impulse of watermelon
Computation:
Impulse = Δp
Impulse = Final momentum - Initial momentum
Impulse of watermelon = Final momentum of water melon - Initial momentum of water melon
Impulse of watermelon = 2 - 50
Impulse of watermelon = -48 kg-m/s
