The current temperature of the Earth is estimated to be approximately 300 Kelvin. Assume for some natural reason (i.e. an asteroid impact or major volcanic eruption), the temperature of the Earth changes to 10C (termed 'new Earth'). Apply the laws of physics discussed in the lectures/textbook to answer the following questions based on this new temperature. Assume that there have been no other changes to the planet (i.e. atmosphere composition, orbit, etc.). 

Question 1: What is the total emitted energy of new Earth? (2 marks)

Question 2: What is the wavelength of maximum energy emission for new Earth? (2 marks)

Question 3: What is the type of radiation calculated in question 2? (i.e. microwave, infrared, ultraviolet, etc.) (1 marks) Question 4: How does the total emitted energy and wavelength of maximum energy emission for new Earth compare to those for the Sun (6000K) and Earth (at 300K)? Why are these values different? (3 marks)
