Q3776467 Inglês
WHAT IS SOCIAL MEDIA ADDICTION?


Whether you use social media to connect with friends and loved ones, watch videos, or simply “kill time,” the popularity of this pastime has increased significantly over the last decade. This is especially the case in children and teenagers, as well as young to middle-aged adults.

So, how does a seemingly harmless hobby turn into an “addiction”?

Like other types of behavioral addictions, using social media can influence your brain in harmful ways. Moreover, you may use social media compulsively and excessively. You can also become so accustomed to scrolling through posts, images, and videos that it interferes with other areas of your life.

Not everyone who uses social media will develop an addiction. Since this activity is becoming more accessible to more people, though, more people may develop an addiction to social media at some point in their lives.


How do you know if you have social media addiction?


A mental health professional can help you determine whether you truly have social media addiction or just really enjoy using it a lot. But there are a few key differences between social media addiction and a habit that you enjoy. These include:


 negative effects to your job or schoolwork due to the overuse of social media.

 increased use during other activities, such as hanging out with friends and family, or while eating.

 increased reliance on social media as a way to cope with problems.

 restlessness and irritability whenever you’re not using social media.

• anger whenever social media usage is reduced.


How can you decrease social media use and prevent its addiction?

Consider the following tips to help you achieve a healthier balance with social media:


 Turn off your personal phone during work, as well as during school, meals, and recreational activities. You can also adjust the setting on each social media app so you can turn off certain notifications.

 Set aside a certain amount of time dedicated to social media per day. Turn on a timer to help keep you accountable.

 Take up a new hobby that’s not technologyrelated. Examples include sports, art, cooking classes, and more. Let yourself be in control of your life — not your social media account.

Q3776444 Geografia
Considere o texto sobre a agricultura no Brasil.

Ao longo da história, o setor da agricultura no Brasil passou por diversos ciclos e transformações, indo desde a economia canavieira, pautada principalmente na produção de cana-de-açúcar durante o período colonial, até as recentes transformações e expansão do café e da soja. A modernização da agricultura no Brasil atual está diretamente associada ao processo de industrialização ocorrido no país, fator responsável por uma reconfiguração no espaço geográfico e na divisão territorial do Brasil. Nesse novo panorama, o avanço das indústrias, o crescimento do setor terciário e a aceleração do processo de urbanização colocaram o campo economicamente subordinado à cidade.

Q3776402 Inglês
The rise of reusable rockets: transforming the economics of space travel

By Adam Stockley


Various theoretical designs of reusable launch vehicles (rockets) have been tested during the history of space flight, but they generally proved too expensive or impractical to implement.  

In the 21st century, the rise in industry privatisation led to several companies taking the lead in reusable launcher development. Their focus is on fully-reusable systems.

The potential of reusable rockets to transform the economics of space travel should be evident. Even so, let’s break down the benefits and drawbacks of this technology to understand more.


The Benefits of Reusable Rockets


The most obvious benefit of a reusable rocket is cost savings. Unsurprisingly, it’s much cheaper to refurbish and relaunch a rocket than it is to build a new one. Reusable rockets also use less fuel than their expendable counterparts, making them comparatively better for the environment.


The Drawbacks of Reusable Rockets


The main disadvantage of reusable rockets is their reduced load capacity. By extension, they must be built to survive the difficulties of launch and re-entry, meaning there is much more extra stabilisation equipment. Therefore, the rockets are heavier.


The Long-Term Viability of Reusable Launchers


The bottom line is that now we have a firmer understanding of the concept of reusable launchers, their potential impact is limitless. However, there are some issues to resolve in terms of extra weight and reduced load capacity, but the space industry is very near to perhaps its biggest revolution in terms of cost reduction and accessibility.
