- The sun produces energy via nuclear fusion at the rate of 4x10 J/s. Based on the proposed overall fusion equation, how long will the sun shine in years before it exhausts its hydrogen fuel? (Assume that there are 365 days in the average year.) Express your answer to one significant figure and include the appropriate units.Our Sun shines bright with a luminosity of 3.828 x 1026 Watt. Her energy is responsible for manyprocesses and the habitable temperatures on the Earth that make our life possible.(a) Calculate the amount of energy arriving on the Earth in a single day.(b) To how many litres of heating oil (energy density: 37.3 x 106J/litre) is this equivalent?(c) The Earth reflects 30% of this energy: Determine the temperature on Earth’s surface.(d) What other factors should be considered to get an even more precise temperature estimate?On Dec 5, 2022, scientific history was made at the Lawrence Livermore National Laboratory (LLNL) in Livermore, California when nuclear fusion was achieved when the 192 lasers deposited about 2 Megajoules (MJ) of energy into a frozen pea sized deuterium-tritium pellet and ignited the pellet through nuclear fusion to release 3 MJ of energy. The metric prefix mega means million (10^6). a) How much mass (kg) would be required to release 1 MJ of energy?
- Our Sun shines bright with a luminosity of 3.828 x 10^26 Watt. Her energy is responsible for many processes and the habitable temperatures on the Earth that make our life possible. (a) Calculate the amount of energy arriving on the Earth in a single day. (b) To how many litres of heating oil (energy density: 37.3 x 10^6 J/litre) is this equivalent? (c) The Earth reflects 30% of this energy: Determine the temperature on Earth’s surface. (d) What other factors should be considered to get an even more precise temperature estimate? Note: The Earth’s radius is 6370 km; the Sun’s radius is 696 x 10^3 km; 1 AU is 1.495 x 10^8 km.In 2011 one estimate of worldwide proven oil reserves was 2.0 x 1011 m3. Using the data in Table 13.1, answer the following questions. (a) How much energy would that amount of oil produce? (b) If oil were the sole source of energy for the world, how long would it last, assuming a steady yearly energy consumption of 500 EJ (5.0 x 1020 J)? (c) How much uranium used to fuel nuclear reactors would be required to supply the amount of energy you found in (a)?The Sun emits 3.839 x 1026 J of energy every second, which is generated from the fusion of hydrogen into helium in its core. Using Einstein's equation E = mc2 (with c = 2.9979 x 108 m/s), determine how much mass the Sun converts to energy every second due to nuclear fusion in its core. If we assume that the Sun has been shining at this same rate through its entire 4.6 billion year history, how much mass has the Sun lost due to nuclear fusion during its lifetime? Express your answer as a fraction of the Sun's current mass (1.9891 x 1030 kg).

How many atoms are there in Earth?The solar power per unit area at the Earth's distance from the sun--called the "solar constant"--is 1.36 kW/m^2. If a solar power station in a sunny location uses 20%-efficient solar panels, what area of panels is required to replace a 1.0 GW power plant at noon. Express the answer in square kilometers. 3676A speck of carbon dust may contain as many as 30 billion atoms of carbon, each atom having a mass of 2.00 x 10-23 grams. Suppose the mass of all the atoms in a speck of carbon dust were converted entirely to energy and applied to the kinetic energy of a baseball. How fast would the baseball be moving? (Mass of baseball = 0.145 kg. ) (1 gram = 1 x 103kg) (KE = ½ mv2) (1 billion = 1 x 109)
