Because of your knowledge of physics and interest in the environment, you have gotten a summer job with an organisation which wants to orbit a satellite to monitor the amount of chlorine ions in the upper atmosphere over Australia. It has been determined that the satellite should collect samples at a height of 100 km above the Earth's surface. Unfortunately, at that height air resistance would make the amount of time the satellite would stay in orbit too short to be useful. ...
... On average, photons of energy may take about 40 000 years to travel from the centre of the Sun to its surface, that is equivalent to about 2cm per hour which is much, much slower than a snail's pace. ... As a by-product, the fusion reactions in the Sun's core also generate a multitude of particles called neutrinos. ... Meanwhile the neutrinos created in the core leave the photons standing as they zip through the Sun's outer layers in just over a couple of seconds and escape into space. ...

With high pressure, compressed gases, hazards can result from improper handling. For example, a leaking cylinder could produce a toxic atmosphere, anesthetic, asphyxiate, or explosive; and with a rapid escape, the cylinder becomes a randomly directed missile. ... Valve hand wheel: used to open and close the cylinder valve. ... Safety device: to permit gas to escape if the temperature gets high enough to endanger the cylinder by increased unsafe pressures. ... Store cylinders vertically. ...
