From the otherside
And straight from Heaven
Vorige week woensdag was ik betrokken bij een kettingbotsing (5 auto's) op de ringweg A10 rond Amsterdam. Helaas werd mijn Volvo C70 behoorlijk in de prak gereden aan de achterzijde. Resultaat is dat ik ook nog doorgedrukt werd tegen mijn voorganger. Repareren maar.... Leenauto.... de nieuwe XC60, woow wat een auto. Snel maar even een paar foto's gemaakt met een onweersbui op de achtergrond. Jammer van de kleur misschien maar met deze achtergrond komt het wel goed uit, natuurlijk heb ik me weer behoorlijk uitgeleefd met Photoshop. Er volgen nog wel wat extremere opname van deze XC60. Nu helaas geen tijd meer voor. Enjoy.
The cause of thunder has been the subject of centuries of speculation and scientific inquiry. The first recorded theory is attributed to the Greek philosopher Aristotle in the third century BC, and an early speculation was that it was caused by the collision of clouds. Subsequently, numerous other theories have been proposed. By the mid-19th century, the accepted theory was that lightning produced a vacuum. In the 20th century a consensus evolved that thunder must begin with a shock wave in the air due to the sudden thermal expansion of the plasma in the lightning channel. In a fraction of a second the air is heated to a temperature approaching 28,000 °C (50,000 °F)[. This heating causes it to expand outward, plowing into the surrounding cooler air at a speed faster than sound would travel in that cooler air. The outward-moving pulse that results is a shock wave, similar in principle to the shock wave formed by an explosion, or at the front of a supersonic aircraft. More recently, this consensus has been eroded by the observation that measured overpressures in simulated lightning are greater than what could be achieved by the amount of heating found. Alternative proposals rely on electrodynamic effects of the massive current acting on the plasma in the bolt of lightning.
A flash of lightning, followed after some seconds by a rumble of thunder is, for many people, the first illustration of the fact that sound travels more slowly than light. Using this difference, one can estimate how far away the bolt of lightning is by timing the interval between seeing the flash and hearing thunder. The speed of sound in dry air is approximately 343 m/s or 1,127 feet per second or 768 mph (1,236 km/h) at 68°F (20 °C). The speed of light is high enough that it can be taken as infinite in this calculation. Therefore, the lightning is approximately one kilometer distant for every 2.9 seconds (or one mile for every 4.6 seconds). In the same five seconds the light could have circled the globe 37 times. Thunder is seldom heard at distances over 24 kilometers (15 miles). A flash of lightning and a simultaneous sharp "clap!" of thunder, a thunderclap, therefore indicates that the lightning strike was very near.
The Volvo XC60 is a compact crossover SUV produced by Volvo. It was
revealed in production form at the 2008 Geneva Motor Show. It went on
sale in Europe in late 2008, and in the North American market in early
2009 as a 2010 model.
Volvo will produce the XC60 with both gasoline- and diesel-burning engines. In North America, only the gasoline-engine will be available. The XC60 shares technology with the Land Rover Freelander of 2007, using a modified version of the Volvo Y20 platform. The Land Rover LR3 will set the stage for these corporate siblings to enter the market, as much of the engineering and tuning of this CUV was done by Volvo in Sweden, only offroad capabilities were done at Land Rover in England. The project director for the XC60 is Lars Blenwall.
The XC60 features Volvo's T6 straight-6 turbocharged 281 hp (210 kW) engine, Haldex Traction AWD.
The XC60 is projected to include traditional Volvo safety features that would include whiplash protection system, side impact protection system, roll stability control, dynamic stability and traction control, inflatable curtain), hill descent control, collision warning with brake support, active bi-xenon lights, and patented front, side, and rear structures. The XC60 also introduces a new technology feature that Volvo has named City Safety. The system is described as a driver support system with the goal of preventing or mitigating vehicle-on-vehicle collisions below 19 mph (31 km/h); it does so through the use of a closing velocity sensor that helps determine whether a collision is likely. Depending on the speed, if a collision is likely, the Volvo's computer system will either prepare the car to brake or automatically brake the vehicle to avoid or mitigate a rear-end collision . Volvo also implemented the system to assist in towing caravans and trailers.
