For example, consider electron–positron annihilation, in which the rest mass of individual particles is destroyed, but the inertia equivalent of the system of the two particles (its invariant mass) remains (since all energy is associated with mass), and this inertia and invariant mass is carried off by photons which individually are massless, but as a system retain their mass. This is a reversible process – the inverse process is called pair creation – in which the rest mass of particles is created from energy of two (or more) annihilating photons. In this system the matter (electrons and positrons) is destroyed and changed to non-matter energy (the photons). However, the total system mass and energy do not change during this interaction.
What is it called when the rest mass of individual particles is destroyed but the inertia equivalent of the system of the two particles remains?
****
The answer: electron–positron annihilation

IMF's forecast said that Greece's unemployment rate would hit the highest 14.8 percent in 2012 and decrease to 14.1 in 2014.  But in fact, the Greek economy suffered a prolonged high unemployemnt. The unemployment figure was between 9 per cent and 11 per cent in 2009, and it soared to 28 per cent in 2013. In 2015, Greece's jobless rate is around 24 per cent. It is thought that Greece's potential output has been eroded by this prolonged massive unemployment due to the associated hysteresis effects.
What was Greece's unemployment rate between in 2009?
****
The answer: 9 per cent and 11 per cent

Since June 2007, YouTube's videos have been available for viewing on a range of Apple products. This required YouTube's content to be transcoded into Apple's preferred video standard, H.264, a process that took several months. YouTube videos can be viewed on devices including Apple TV, iPod Touch and the iPhone. In July 2010, the mobile version of the site was relaunched based on HTML5, avoiding the need to use Adobe Flash Player and optimized for use with touch screen controls. The mobile version is also available as an app for the Android platform. In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system. According to GlobalWebIndex, YouTube was used by 35% of smartphone users between April and June 2013, making it the third most used app.
When did youtube become available on Apple products?
****
The answer:
June 2007
