Balloon Professor Charles : How do people learn to fly

Cycle time of Venus round the Sun (i.e. Duration venerianskogo year) — 225, and the period of rotation of a planet about the axis—243 terrestrial days (siderichesky the period). These data have been received by means of a radar-location independently from each other on seven observatories of four countries of the world by two various methods

And, and it for us the main thing, half (or it is more) gases is necessary on steams of water which at the given eruption have made '/Р· volume of water of Caspian sea.

Let's make the following experiment. We take a decimeter cube of clay and we will try to define degree of water penetration of breed. We will admit, that this clay vodouporna. However even if to reject such important factor as a difference of geological and human time it is improbable that the decimeter sample of clay taken by us on the uniformity completely answers all layer with the area, we will admit 1 РєРј2, let alone bolshej the layer areas

Such sources are available, for example, in France near Clermont-Ferrand, and also in Italy nearby to Rome. It Tivoli and the Dignity-filippo which all for 20 years have filled a pond with a 9-metre layer travertina (tufa) and was formed nearby by layers of a tufa capacity about 100 m.

The area of all lakes of a planet a little less the area of Mediterranean sea (2,7 against 3 billion РєРј2), total volume of water of all lakes of 250 thousand РєРј3; it only three times exceeds the annual expense of Neva, At the same time '/Р· weights of water of all lakes of our planet belongs to Caspian sea.

Separate layers can differ from each other] either on temperature, or on минерализации23, either on density, or on speeds of a current, or ' on a combination of these signs. These characteristics can change not only in vertical, but also in a horizontal direction. Borders of the last do not carry the name of fronts.

Though on continents of our planet some millions chinks are drilled, depth of their overwhelming number is very insignificant and is measured by tens and hundreds metres. Depths of prospecting and operational chinks on oil and gas average about 3 km. In the USA in the State of Oklahoma the chink by depth to 9159 m. is drilled

Plants from 229 to 254, and at coniferous 102—154.

From all told it is possible to draw a conclusion that solubility of gas in natural water at constants to temperature and mineralization degree is directly proportional to pressure of gas upon a liquid, ' for gas mixes it is proportional to pressure of each gas separately. But it is fair for rather small pressure. At considerable pressure, for example on the big depths at ocean where pressure sometimes reaches hundreds and even thousand atmospheres, on solubility of gases in water speech ahead influences not partsialnoe pressure of separate gases, and the general pressure of all water column, but about it

And, at last, well remembering how flight mythical Ikara and many other things has tragically ended, already real daredevils, Leonardo da Vinci has thought of safety letanija. It does a parachute sketch, like piramidoobraz th tent with cords on corners, keeping for which, the person could go down from height safely.
