Refer to the graph shown below. If you had a piece of chicken that started with 1000 live Salmonella cells, how long would you need to cook it to reduce the number to 10 cells? Image description: The y-axis is the number of surviving cells (log scale) starting at 1 cells and going up to 10,000 cells. Each tick mark is one log difference. The x-axis is the time in minutes at the desired temperature. Each tick mark is 5 minutes.

The International Space Station is orbiting at an altitude of about 370 km above the earth’s surface. The mass of the earth is 5.97 × 1024 kg, the radius of the earth is 6.38 × 106 m, and G = 6.67 × 10−11 N∙m2/kg2. Assume the orbit is circular. (a) What is the period of the International Space Station’s orbit in seconds? (b) What is the speed of the International Space Station in its orbit? (c) The ISS has a mass of approximately 4.45 × 105 kg. Calculate the total mechanical energy of the ISS in its orbit.
