A balloon flies because the widely seperated molecules of a thin gas

10-11 класс

such as hydrogen or of the heated air that expands inside the bag, are
less dense and thus ligher than those of are air outside the bag. In
attempting to rise or escape from its confinement, the buoyant
lightweight gas or heated air lifts the balloon along with it.

Normally, when somethong soars skyward, it does so by virtue of its
aerodynamic desingn. Like an airplane, it is lifted by the effect of
outside forces, usually wind, upon its surface. It does not soar because
it is lighter than the surrounding atmosphere. Even a feature in the
breeze is an aerodynamic form. It flies solely by the forse of air
currents playing upon it. If the breeze stops, the feather slowly floats
to earth. ПОЖАЛУЙСТА ПОМОГИТЕ СРОЧНО ПЕРЕВЕСТИ ТЕКСТ НА РУССКИЙ!!!!

Шар летит, потому что находящиеся далеко друг от друга молекулы разреженного газа такого как водород или нагретого воздуха, который расширяется внутри сумки, меньшей плотности и, соответственно, легче, чем воздух, находящийся снаружи (сумки). Пытаясь улететь или утечь из своей "тюрьмы", плавучий легковесный газ или нагретый воздух поднимает шар выше вместе с собой.

Обычно, когда что-нибудь парит ввысь, оно делает это из-за какой-либо силы или своего аэродинамического дизайна. Как аэроплан, он поднимается благодаря влиянию внешних сил, обычно ветра, который дует относительно его поверхности. Он не парит, потому что легче, чем окружающая атмосфера. Даже перо, поднятое ветром, аэродинамической формы. Оно летит исключительно благодаря силе ветра, чьи потоки играют с ним. Если ветер остановится, то перо медленно поплывет к земле.

Belgium has always had a lot more than the faceless administrative buildings that you can see in the outskirts of its capital, Brussels. A number of beautify historic cities and Brussels itself offer impressive architecture, lively nightlife, first-rate restaurant and numerous other attractions for visitors. Today the old-fashioned idea of 'boring Belgium' has been well and truly forgotten, as more and more people discover its very individual charms for themselves.
B. Nature in Belgium is varied. The rivers and hills of the Ardennes in the southeast contrast sharply with the rolling plains which make up much of the northern and western countryside. The most notable features are the great forest near the frontier with Germany and Luxembourg and the wide sandy beaches of the northern coast.
C. It is easy both to enter and to travel around pocket-sized Belgium which is divided into the Dutch-speaking north and the French-speaking south. Officially the Belgians speak Dutch, French and German. Dutch is slightly more widely spoken than French, and German is spoken the least. The Belgians, living in the north will often prefer to answer visitors in English rather than French, even if the visitor's French is good.
D. Belgium has a wide range of hotels from 5-star luxury to small family pensions and inns. In some regions of the country, farm holidays are available. There visitors can (for a small cost) participate in the daily work of the farm. There are plenty of opportunities to rent furnished villas, flats, rooms, or bungalows for a holiday period. These holiday houses and flats are comfortable and well-equipped.
E. Belgian style of cooking is similar to French, based on meat and seafood. Each region in Belgium has its own special dish. Butter, cream, beer and wine are generously used in cooking. The Belgians are keen on their food, and the country is very well supplied with excellent restaurants to suit all budgets. The perfect evening out here involves a delicious meal, and the restaurants and cafes are busy at all times of the week.
F. As well as being one of the best cities in the world for eating out (both for its high quality and range), Brussels has a very active and varied nightlife. It has 10 theatres which produce plays in both Dutch and French. There are also dozens of cinemas, numerous discos and many night-time cafes in Brussels. Elsewhere, the nightlife choices depend on the size of the town, but there is no shortage of fun to be had in any of the major cities.
G. There is a good system of underground trains, trams and buses in all the major towns and cities. In addition, Belgium's waterways offer a pleasant way to enjoy the country. Visitors can take a one-hour cruise around the canals of Bruges (sometimes described as the Venice of the North) or an extended cruise along the rivers and canals linking the major cities of Belgium and the Netherlands.

The skeleton is composed of bones. In the adult the skeleton has over 200 bones.

The bones of the skull consist of cranial and facial parts. There are 26 bones in the skull.

The bones of the trunk are the spinal column or the spine and the chest (ribs and breastbone). The spine consists of the cervical, thoracic, lumbar and sacral vertebrae and the coccyx.

The vertebra is the small bone, which is formed by the body and the arch. All the vertebrae compose the spinal column or the spine. There are 32 or 34 vertebrae in the spine of the adult. There are seven cervical vertebrae, twelve thoracic vertebrae, five lumbar, five sacral vertebrae and from one to five vertebrae which form the coccyx in the spinal column. The cervical part of the spine is formed by seven cervical vertebrae. Twelve thoracic vertebrae have large bodies. The lumbar vertebrae are the largest vertebrae in the spinal column. they have oval bodies.

The chest (thorax) is composed of 12 thoracic vertebrae, the breastbone and 12 pairs of ribs. The breastbone is the long bone in the middle of the chest. It is composed of three main parts. The basic part of the chest is formed by the ribs. On each side of the chest seven ribs are connected with the breastbone by cartilages. The cartilages of three other ribs are connected with each other and with the seventh rib. But the cartilages of these ribs are not connected with the breastbone. The eleventh and the twelfth ribs are not connected with the breastbone either. They are not connected with other ribs, they are free. Each rib is composed of a head, neck and body.

The lower extremity consists of the thigh, leg and foot. It is connected with the trunk by the pelvis. The upper extremity is formed by the arm, forearm and hand. It is connected with the trunk by the shoulder girdle.

The bones of the skeleton are connected together by the joints or by the cartilages and ligaments. The bones consist of organic and inorganic substance.

Перевести на русский язык с умом (как lag2003) The most Glamorous Aspect of Police Work The basic

responsibility of the police is to fight crime, maintain order, and provide miscellaneous services to the public. Patrol remains the basic manner in which police services are delivered to the public.

Criminal investigation is the most glamorous aspect of policing. Most police officers regard detective work as “real” police work. Detective work has a specific mission: apprehending the offender. The quality of work can also be measured in terms of the number of arrests. This contrasts sharply with patrol duty, which largely involves peace-keeping. Good detectives are believed to be able to solve most crimes, so the citizen-victim becomes angry when the police fail to solve the crime he or she suffered from.

The process of investigating a crime involves several different steps performed by at least three different units within the police department: patrol officers, detectives, criminalistics technicians. the two major stages of the investigation process are the preliminary investigation and the follow-up investigation.
