A Unit 1 8 Environment The Melting Ice Caps The world's ice is melting, and it is happening at an alarming speed, rate, 3 Global warming has been increasing at a very unsustainable² and the polar ice caps have been vanishing³ before our eyes. In the 55 years between 1961 and 2016, the Earth's total ice loss amounted to an estimated nine trillion³ tons. The start of the 21st century bore witness to several profound decreases in terms of the area covered annually by Arctic ice. The year 2012 was the lowest on record, while 2007, 2016, and 2019 were tied for second-lowest. 10 As the ice melts, an excessive amount of melted water emerges from it. This large amount of melted water manifests itself as a rise in sea levels. (This rise leads to the increased erosion -or wearing away- of the coast. When combined with the higher frequency of ecological" disasters¹2, it results in a bigger storm surge¹3. Climate change threatens¹4 15 to forever change the way we live.

Problem 28. Consider the process A* + A+), and A* is stationary (at rest). This is the process that an excited atom emits a photon and goes back to the ground state atom A. Assume that the excited atom has a rest mass M6. Show that v-mi (loro) hvo (4.3.14) = 1 2M where v is the photon frequency if the recoil is taken into account, and vo is the photon frequency if the recoil is not taken into account.
