- Delay time for communication between GEO satellites and Earth. Use the relationship between distance (d), time (t) and speed (v), d = vt to repeat the calculation we did in class, but this time using the English units. Use the fact that GEO satellites orbit at 22,236 miles above Earth's equator, and that the speed of light is 1.86 x 105 mi/s. (Note that both of these values are equivalent to those used in class.) You may want to write this calculation on paper and insert a photo here.Calculate the angle a person needs to lean from the vertical when 1. walking a 14 m (radius) circular track at 22 mins per mile, and Enter to 2 significant figures Angle with respect to the vertical = = 0.85 ! No, that's not the correct answer. O 2. running at 4 min per mile. Enter to 2 significant figures Angle with respect to the vertical = 6.8 Use 1 mile = 1609.4 m Sense-making: Do your results for the leaning angle during walking agree with your observations about people walking on circular tracks? Oplain your answer. The formula for potential energy is PE = m g h. In this formula, PE stands for potential energy (in joules), m stands for mass (in kilograms), h stands for height (in meters), and g stands for acceleration caused by gravity. On Earth's surface, g is 9.8 m/s?. This means that every second, the speed of a falling object increases by 9.8 m/s. Calculate the potential energy of a 20 kg sled at 40 meters. Show your work. When you are done, use the Gizmo to check your answer.
- Oxygen Atoms in People. Figure 5.7 shows that oxygen makes up about 65% of the mass of a human being. A single oxygen atom has a mass of 2.66 × 10−26 kg. (a) Use this fact to estimate the number of oxygen atoms in your body. (Hint: If you know your weight in pounds, you can convert to kilograms by dividing by 2.2.) (b) Compare your answer to the number of stars in the observable universe (which is roughly 1022).Impact Energy. Consider a comet about 2 kilometers across with a mass of 4 × 1012 kg. Assume that it crashes into Earth at a speed of 30,000 meters per second (about 67,000 miles per hour). a. What is the total energy of the impact, in joules? (Hint: The kinetic energy formula tells us that the impact energy in joules will be 1 × m × v2, where 2 m is the comet’s mass in kilograms and v is its speed in meters per second.) b. A 1-megaton nuclear explosion releases about 4 × 1015 joules of energy. How many such nuclear bombs would it take to release as much energy as the comet impact? c. Based on your answers, comment on the degree of devastation the comet might cause.According to modern science, Earth is about 4.5 billion years old and written human history extends back about 10,000 years. Suppose the entire history of Earth is represented with a 100-meter-long timeline, with the birth of Earth on one end and today at the other end. a. What distance represents 1 billion years? b. How far from the end of the timeline does written human history begin? a. 1 billion years is represented by meters of the timeline. (Type an integer or decimal rounded to the nearest tenth as needed.) millimeters from the end of the timeline. b. Written human history begins about (Type an integer or decimal rounded to the nearest hundredth as needed.)

- Answer it correctly please. Explain your answer. I will rate accordingly with multiple votes.Part I. We will leam in this class that the distance from the Earth to the Sun is approximately 1AU = 150,000,000 kilometers. a. Convert this number to meters (1 kilometer = 10° meters) and express it using scientific notation: 150000000000 meters How else might you express this number? (Millions, billions, etc. ?) b. A car on the highway drives at 55 mph = 25 meters per second. How long would it take to drive to the Sun? (Assuming you have a car that works in outer space.) Use the equation distance = velocity x time, or time = distance / velocity. Time = distance/velocity = , seconds (don't forget to use scientific notation.) How many days?. _days How many years?. years Does the answer surprise you?The international space station (ISS) orbits 400 km above Earth's surface at 7.66 km/s (17,100 mph). Suppose the ISS is moved to 400 km above Mars. 1. To maintain its orbit above Mars, will the ISS have to move faster or slower that its orbital speed around Earth? Justify your answer. 2. Will astronauts on the ISS feel lighter, heavier, or no change at all while in orbit around Mars. Explain your answer.
