1.How does inertia affect a person who is not wearing a seatbelt during a collision?

1 answer:

6 0

1. during a collision, the person not wearing a seatbelt is already in motion. there is no outside force (the seatbelt) to stop this motion.
2. Kinetic Energy = 0.5 * m * v^2 because velocity is a squared term, doubling the velocity actually quadruples the kinetic energy, making the stopping distance much much greater
3. by the same logic as above, mass is not a squared term, therefore doubling the mass will double the kinetic energy, increasing the stopping distance -- but by not as much as increasing the velocity.
4. because a driver cannot alter the mass of his vehicle, the best way to enter sharp curves would be decreasing velocity (speed)
5. there are many factors that determine the degree of damage (to humans and property in a crash), most notably the size of the vehicle(s) and velocity.

What are some differences between CUI and GUI ?

ollegr [7]

Answer:

Even though both are interfaces and serve its purpose of attempting to run the strategies, their components as well as the manipulate they will get from the patient differ.

Explanation:

CUI (Character User Interface) :-

It's a sort of user interface that only uses binary data and pseudographics for interface-output and data sessions.
That's characterized by low availability for operating systems I / O resources (act with integrity) and high speed with a display of data.

GUI (Graphical User Interface (GUI):-

Using graphical elements such as windows, icons, menus helps the user to communicate with the program.
It is a kind of user interface along which people interact with electronic equipment through characterizations of visual indicators.

Use EBNF notation to describe the syntax of the following language constructs.

ZanzabumX [31]

Answer:

Following are the description to the given points:

Explanation:

To resolve basic design restrictions, EBNF has also been developed.This principle was its lack of support can identify repeatings easily. It implies that popular BNF models, like the description of a sequence of replicable elements, are complicated and rely on contra intuitive logical math.

To set a list of words divided by commas (e.g. john, coffee, logic) for instance, we would like to say something like "a list is a word accompanied by a few commas or terms." Through EBNF, they may say so. However, there have been no "many" alternatives in the standard BNF format. So, to describe something such as "a list is a term or a number accompanied by a pair with notation and script," you have to say the same thing. Which functions, although it is difficult, as it specifies a variety of lists instead of a specific list.

Essentially, "john, coffee, logic is John's list, accompanied by coffees or, and logic" would be the earlier link. That's why in Option (a):

The return statement in Java is:

return ('”‘ (~[“] | ” [”e‘])*);

In option (c), it is the valid statement.
