Radium-226 has a half-life of 1,285 years. How long would it take for a sample of Radium-226 to reach 5 half-lives?

Answers

Answer 1

Answer:

6425 years

Explanation:

Half life refers to the time taken for a radioactive substance to decay to half of the original number of atoms present in the sample.

Some radioactive nuclides have short half lives while others have long half lives.

If 1 half life of Radium-226 is 1,285 years

Then, five half lives = 5 * 1,285 years = 6425 years

Answers

Answer:

One advantage of using Cash for all purchases is that Cash is not likely to be subject to Finance Charges

Explanation:

The simplest advantage to paying with cash is the limitation it puts on what you buy. Without a buy-now-pay-later mentality associated with credit cards, you will purchase only items that are affordable, and covered by the cash you have on hand. This way, you never have to worry about buying anything you can't afford at the moment.

How does a Free Market System and Centrally Planned System impact consumers and producers differently?

Answers

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

A Free Market System and Centrally Planned System impact consumers and producers differently in that in the Free Market System, it is the supply and demand, the factors that decide the price of goods and services. On the other hand, in a Centrally Planned system, it is the intervention of the state -the government- which decides the price of the goods and services in a fixed way.

In total opposition to a free-market economy where individuals promote capitalist ideas to invest money and create companies to be rich, in a  central system or command economy is the state the one that owns the means of production. The central government decides the kind of products to be produced, the price of the products, how to produce the goods, and the amount that is going to be produced.

¿Qué tendría que hacer Daniela para resolver su enojo? ¿Qué tendría que hacer José
para recuperar la amistad de Daniela? ¿Qué hubieran hecho ustedes antes una situación
como esta?

Answers

La respuesta correcta para esta pregunta abierta es la siguiente.

Desafortunadamente, se te olvidó incluir el texto de referencia. ¿A qué texto, artículo, o lectura te refieres? Tú lo sabes, pero nosotros no. Se te olvidó anexarlo.

¿Cómo te ayudamos si no conocemos la historia?

Tratando de ayudarte, hicimos una profunda investigación y podemos comentarte lo siguiente.

Probablemente, el texto se refiera a la historia de los amigos Daniela y José, que se llevaban muy bien hasta que José se hizo novia de otra muchacha, y no se lo contó a Daniela porque sabía que no lo iba a entender y Daniela se iba a enojar.

Y así pasó. Daniela se enojó y escribió cosas negativas en sus redes sociales.

De ser así, podemos comentar las siguientes preguntas:

Comenten las preguntas:

¿Cuál consideran que sería la solución?

Deben de sentarse y hablar para aclarar las cosas. Cada uno tiene su versión y hasta que no platiquen de forma madura, con respeto, no van a poder hablar con sinceridad y resolver sus diferencias.

¿Qué emociones tienen que regular cada uno?

En el caso de Daniela, debe controlar su frustración y enojo por el noviazgo de José. A final de cuentas, ella sí siente algo por José. De lo contrario, no hubiera reaccionado de esa manera. En el caso de José, debe abrirse más y confiar en los demás para comunicar a tiempo sus ideas y no herir otros sentimientos.

¿Qué tendría que hacer Daniela para resolver su enojo? ¿Qué tendría que hacer José para recuperar la amistad de Daniela?

Como dijimos en la primera respuesta, lo primero es sentarse y hablar como personas maduras. Ambos eran buenos amigos antes del incidente que los separó. Existe el cariño para que se vuelvan a entender. El asunto es que los dos deben ser sinceros, humildes, y si es necesario pedir disculpas, pues que las pidan y sean capaces de perdonar.

¿Qué hubieran hecho ustedes antes una situación como esta?

Primero que nada, ser sinceros desde el principio, y no mandar mensajes que pudieran mal interpretarse.

Después, siempre ser honestos y abiertos para aclarar cualquier duda en el momento. Daniela se hizo ilusiones de algo que nunca fue, y eso le afectó mucho. Y si ya se generó un problema o mal entendido, pues aclararlo de inmediato.

After comparing these readings, which explanation do you believe best represents the true meaning of jihad In Islam? Why?

Answers

Answer:

It is the Islamic word for an internal struggle against evil or a physical struggle with non-Muslims.

Explanation:

Comparing the readings, it is clear that the definition that most accurately captures the true meaning of jihad in Islam is that it refers to a battle or an endeavor to advance what is right and to avert what is evil.

Jihad is a term that refers to any endeavor to bring one's social and personal life into compliance with God's will, and is not just used to describe military action. Particularly in the West, where it has been incorrectly interpreted as "holy war," the term "jihad" has been misconstrued and used inappropriately.

The "Greater Jihad" and the "Lesser Jihad," two fundamental theological interpretations of jihad, respectively. The Greater Jihad is the war against the lower self, the struggle to purify one's heart, practice goodness, stay away from evil, and improve oneself.
