Assinale as propriedades que podem permitir ao estudante a identificação desses líquidos.

I. A energia cinética média das moléculas dos gases ideais X e Y depende apenas da temperatura absoluta em que se encontram.

II. A velocidade média das moléculas dos gases ideais X e Y depende da temperatura absoluta em que se encontram e da natureza de cada gás.

III. Se Mx > My, a velocidade média das moléculas do gás ideal X é maior que a velocidade média do gás ideal Y.

I. A superposição de duas ondas transversais idênticas em fase produz uma onda com amplitude aumentada.

II. A superposição de duas ondas longitudinais idênticas fora de fase produz o cancelamento mútuo.

III. Quando a frequência de vibração forçada de um objeto se iguala à sua frequência natural ocorre um dramático aumento da amplitude. Esse fenômeno é denominado ressonância.

Acupuncture is an important component of Traditional Oriental Medicine (TOM) that involves the insertion of thin needles at specific points (acupoints), which are primarily located along meridians. The TOM theory of acupuncture is based in part on the premise that there are patterns of energy flow composed of Qi (pronounced Chee) throughout the body. This energy flow is required for good health; blockages in Qi lead to pain and ill health. (All traditional oriental medicine practices are focused on improving the flow and balance of Qi.) Thus, according to TOM practitioners, the use of acupuncture stimulates certain points in the energy channels, restoring (or maintaining) a healthy flow and balance. TOM practitioners use acupuncture to treat and prevent a range of conditions and illnesses, even colds and flu. In the U.S., one of its most common uses is to relieve pain, but it is also used for a host of other conditions ranging from ear, nose and throat disease to neurological and respiratory problems and even depression. Acupuncture may be the only intervention used, or it may be used in conjunction with other Oriental therapies such as herbs, or with more conventional therapies. Widely practiced around the world, especially in Asia (the practice originated in China) and Europe, acupuncture didn’t gain a notable following in the U.S. until the 1970s, after President Richard Nixon’s visit to the People’s Republic of China. James Reston, a member of the press corps accompanying Nixon, also piqued public interest when he wrote about how physicians in Beijing eased his postsurgery abdominal pain with needles. Acupuncture has been gaining popularity in the U.S. ever since. The World Health Organization (WHO), using different criteria, has recognized acupuncture as an appropriate treatment for more than 40 conditions, including certain digestive, respiratory, neurological, muscular, urinary, menstrual and reproductive disorders.

Going on holiday?

Don’t advertise the fact that your house is empty. Do remember to cancel the milk and newspapers and also to draw curtains back. Don’t leave notes for tradesmen and try not to talk about your holidays and future plans loudly in public. Operate a “Good Neighbour” scheme to ensure that mail is taken in, the house checked regularly and that lights are put on. If you plan to be away for a long time, make sure that your lawn is cut. Call at your local police station and tell them you are going away. Make sure that they know who has your spare key and how you can be contacted in case of trouble. Especially at holiday time, don’t leave cash or valuables in the house ─ take them with you or lodge them with the bank.
