Tasks expansion and deepening Tick the correct statements! 9.3 km = 9.3 · 10 3 m 87 ® = 8.7 · 10 3 m ® 1.26 kg = 1.26 · 10 5 mg 42 t = 4.2 · 10 6 dag 5m = 5 · 10 2 cm 29h ® = 2.9 · 10 3 ® The following data are available about the planet Saturn. Fill in the table! Saturn planetary data floating point representation polar diameter approx. 108,700 km equatorial diameter approx. 1.205 · 10 5 km mean distance from the sun approx. 1.43 billion km In a particle accelerator, temperatures of more than 4 · 10 12 ° C can be generated. Temperatures of approx. 16 · 10 6 ° C prevail in the sun. How much higher is the temperature in a particle accelerator than in the sun? A super telescope, the “Overwhelmingly Large Telescope (OWL)”, enables a view to the edge of our universe of 3 · 10 10 light years. The closest galaxy is the Andromeda Nebula at a distance of approx. 2.2 · 10 6 light years. How much further can one look approximately with OWL into space than to the Andromeda Nebula? The planet earth has a mass of approx. 5.97 · 10 24 kg, the planet Mercury has a mass of approx. 3.3 · 10 23 kg, the planet Jupiter has a mass of approx. 1.9 · 10 27 kg . a) How many times heavier than the earth is Jupiter? b) How many times heavier than Mercury is the earth? c) How many times heavier than Mercury is Jupiter? The size of data stores is measured in bytes (B). A large hard drive fits 2 TB of data, and a Blu-ray disc 25 GB. How many times more data can the hard drive hold than the Blu-ray disc? The human brain has around 200 billion nerve cells. 1) Enter this number in floating point format and in fixed point format! 2) In diseases such as cerebral infarction or Parkinson's, around 40% of these nerve cells can die. How many nerve cells are there? The estimated number of elementary particles in the universe is approximately 10 80. A Googol, that is the number 10 100, gave the search engine “Google” its name. 1) How many times larger than the number of elementary particles is a Googol? 2) Does it even make sense to know a number greater than the number of elementary particles in the universe?
