a photon of energy 113.6 ev ejects an electron from a hydrogen atom in its ground state. what is the kinetic energy in ev of the ejected electron? neglect recoil of the proton.

Answers

Answer 1

A photon of energy 113.6 eV ejects an electron from a hydrogen atom in its ground state, the kinetic energy of ejected electron is 100 eV.

Given data is

Energy of photon, E = 113.6 eV

Energy required for ejecting an electron from the atom is known as ionization energy of an atom.

The ionization energy of hydrogen is 13.6 eV. If the energy of the photon is equal to or greater than the ionization energy of an atom, the electron will get ejected from the atom. The remaining energy will be utilized by the electron in the form of kinetic energy.

Kinetic energy of electron is given by;

K.E = E - IE

Where, E = Energy of photon

IE = Ionization energy of hydrogen

Substituting the values;

K.E = 113.6 eV - 13.6 eV = 100 eV

Therefore, the kinetic energy of ejected electron is 100 eV.

1.Compare exception handling and handling of warnings in embedded SQL, dynamic SQL, JDBC, and SQLJ.2.Answer the following questions.Why do we need a precompiler to translate embedded SQL and SQLJ? Why do we not need a precompiler for JDBC?SQLJ and embedded SQL use variables in the host language to pass parameters to SQL queries, whereas JDBC uses placeholders marked with a ‘?’. Explain the difference, and why the different mechanisms are needed.

Answers

Embedded SQL: In embedded SQL, exceptions and warnings are typically handled using native programming language constructs like try-catch blocks or error handling routines.

Warnings may be retrieved using specific SQL statements or by checking the status variables after executing SQL statements.

- Dynamic SQL: Exception handling in dynamic SQL is similar to embedded SQL, where programming language constructs are used to handle exceptions and warnings. However, dynamic SQL often requires additional care due to the dynamic nature of the queries being executed.

- JDBC: JDBC provides a standardized exception handling mechanism using Java's try-catch blocks. SQLException class is used to handle database-related exceptions and warnings. Additionally, JDBC provides methods to retrieve specific exception details and warnings.

- SQLJ: SQLJ, which is a SQL implementation in Java, uses similar exception handling mechanisms as JDBC. It provides standardized exception classes, such as SQLWarning and SQLException, to handle database-related errors and warnings.

2. Need for precompiler and difference in parameter passing mechanisms:

- Precompiler for embedded SQL and SQLJ: Embedded SQL and SQLJ require a precompiler because they involve embedding SQL statements within host language code (like C/C++ or Java). The precompiler translates the embedded SQL or SQLJ code into standard SQL statements that the database can execute. This translation is necessary to ensure compatibility between the host language and the database.

E. connections usually occur through a public network

Answers

Answer:

B, D, E

Explanation:

The public Internet is largest WAN in the world.

A LAN (Local Area Network) typically uses Ethernet and Wireless Routers to connect devices.

A single business would not usually manage a WAN because this would create a monopoly, which is why competition is intentionally created between Internet Service Providers (ISPs), though sometimes a single business could manage a WAN via MPLS, etc.

Answer:

- connects devices in a large geographic area

- may be controlled by multiple entities

- connections usually occur through a public network

Explanation:

A wide area network (WAN) connects devices across a broader area like a city. It can provide connections across multiple countries. A wide area network may be managed and controlled by multiple entities. LANs connect to WANs to create a network of networks. The internet is considered the largest WAN.

that brake-by-wire systems are not efficient in detecting panic stops. Who is

O a. Technician A
O b. Technician B
O c. Both Technician A and Technician B
O d. Neither Technician A nor Technician B

Answers

The brake-by-wire system can detect panic stops if the driver abruptly releases the accelerator, so Technician A is only partly accurate. Technician B is mistaken because panic stops can be accurately detected by brake-by-wire devices.

How well do brake-by-wire devices work at spotting panic stops?

That period of time and distance can be cut down in a brake-by-wire device. The driver's abrupt release of the accelerator can be detected by the computer, which could be a sign of a panic halt.

why do we analyze the expected running time of a randomized algorithm and not its worst-case running time?

Answers

When values generated by a random number generator are used to determine an algorithm's behavior in addition to its input, the algorithm is said to be random.

You examine what is anticipated for this reason. A worst-case scenario analysis simply considers the input. We rarely have complete control over how an algorithm will be used, therefore we frequently are unable to derive an average-case measurement that is likely to be accurate. The worst-case scenario provides us with a performance upper limit. An algorithm will never do worse than what we determine if its worst case analysis is done. The random coin tosses determine the algorithm's execution time when one is given. The predicted running time is the anticipated length of time given the coin tosses.

What Does Query String Mean?

The part of a URL known as a query string is used to pass information to a back-end database or web application. Because the HTTP protocol is stateless by design, we need query strings. You must continue to operate a website in order for it to function as more than a brochure (store data).

There are several methods for doing this: You can use something like server-side session state on the majority of web servers. Cookies can be used to store data on the client. You can also use a query string in the URL to store data.

All URLs on the internet can be divided into three parts: protocol, file (or program) location, and query string. The majority of the time, the protocol you see in a browser is HTTP.

The location is represented by the hostname and filename in their typical format (for instance, www.brainly.com/somefile.html), and the query string is whatever comes after the question mark symbol ("?").
