Answer:
First of all,there is not theory F=ma^2!!
Its F=ma and they are definitely not the same.Here F means force and E means Energy.
a means acceleration, but c means the velocity of light. Clearly there's difference between acceleration and velocity and force and energy.
F=ma can be applied on things we normally see but E=mc^2 is applied on things that can travel nearly in light speed!which means atoms,molecules, protons,electrons etc. energy can be determined by the Einstein theory but F=ma is for determining human energy, or energy of cars,vehicles or any regular moving things

Answer:
Phishing
Explanation:
Phishing is a social engineering attack where users are asked to respond to an email or are directed to a website where they are requested to login with their personal credentials, such as passwords or credit card numbers.
How Phishing Works?
The attacker first carefully designs a web page identical to a real bank with fine details. Then attacker persuades the victim to go to this fake web page with login screen. The attacker gets all the information typed and enter into that fake web page. The victim often thinks that this is exactly my bank's web page so nothing is going to happen if I put log in credentials.
How to avoid Phishing?
This kind of attack can always be spotted with one simple trick. Check the address of the web page carefully. The attacker can design the web page according to his wish but he cannot have control over the web address of a real bank or real a website.
Some general safety tips are:
- Don't open links from spam emails.
- Don't download malicious software.
- Don't share personal information with strangers
Answer:
1080 x 1920
800 x 600
Explanation:
These are the screen sizes that you can find in the list of the screen sizes, which can be easily found in the document that lists all the screen sizes. You will certainly find the 1080 x 1920 and also the 800 x 600, however, you will not find the 320 x 240 and 800 x 600. The last two are the standard screen sizes and hence are not the correct options. The correct options are as listed above.
