10) The international space station (ISS) orbits the Earth from an altitude of 408 km. a) Calculate the strength of Earth’s gravity on the ISS at that altitude. (Hint: How far is the ISS from the center of mass of the Earth?) b) Earth’s gravity is what keeps the ISS in its orbit (which we will assume is circular). At what speed does the ISS orbit the Earth? Please show working New Equations 2 torque = (lever arm) x (force)...
The magnitude of the tidal force between the International Space Station (ISS) and a nearby astronaut on a spacewalk is approximately 2GmMa/r3 . In this expression, M is the mass of the Earth, r=6.79×106m is the distance from the center of the Earth to the orbit of the ISS, m=125kg is the mass of the astronaut, and a=20m is the distance from the astronaut to the center of mass of the ISS. Calculate the force of gravitational attraction between the...
The magnitude of the tidal force between the International Space Station (ISS) and a nearby astronaut on a spacewalk is approximately 2GmMa/r3 . In this expression, M is the mass of the Earth, r=6.79×106m is the distance from the center of the Earth to the orbit of the ISS, m=125kg is the mass of the astronaut, and a=16m is the distance from the astronaut to the center of mass of the ISS. Part A Calculate the magnitude of the tidal...
The international space station (ISS) orbits the Earth with an approximately circular orbit 420 km above Earth's surface (6790 km above the center of the Earth). Suppose one evening the ISS passes in front of the full moon - which subtends an angle of 30 arc minutes (0.5 degrees)- in such a way that it exactly bisects the moon. How long will it take to cross in front of the Moon from one end to the other, as viewed by...
You sometimes hear about "zero gravity" in places like the International Space Station. Since we know Newton's Law of Gravity, we know that gravity doesn't just "stop" anywhere. What is the ratio of the gravitational force from the earth on something in the International Space Station (orbiting an average of 385 km above Earths surface) to the gravitational force from the earth on that same object when it is on the ground?
The International Space Station, ISS hereafter, has an orbital period of approxi- mately 93 minutes. Determine the following: 12. How fast is the ISS moving? 13. How far above the surface of the Earth is the ISS? 14. Using only your answer to question 12 and the given orbital perdiod of the ISS, determine how high the Hubble Space Telescope orbits above the surface of the Earth, if its orbital period is 95.42 minutes 15. If NASA launched portable rocket-boosters...
Typed please. For an orbiting space station, ideally, the occupants would experience simulated gravity. One way to do so is to have the space station rotate. How could this simulate gravity? Would the occupants feel a centripetal force, and if so, what is the source?
QUESTION 17 The International Space Station which presently has mass of about 420,000 kilograms, maintains an orbit with an altitude of between 330 and 435 kilometers (205 and 270 miles respectively) above the Earth surface by means of re-boost maneuvers using the engines of the Zvezda module or visiting spacecraft to compensate for 2 km/month orbital decay due to the atmospheric drag. Calculate the following for the low orbit of the ISS (330 kilometers above the Earth surface), assuming that...
There are three different oxygen generation systems onboard the International Space Station (ISS). Assume all three are currently running. System 1 is operational 90% of the time and supports 4 crewmembers. System 2 is operational 60% of the time and supports 6 crewmembers. System 3 is operational 80% of the time and supports 3 crewmembers. In an abnormal event, indicators at Mission Control show that one of the 3 systems has failed. What is the probability that there is an...
#1. ["Massing' Astronauts) Inside the International Space Station orbiting Earth, ordinary scales don't work for measuring weight since the space station is in free fall. However, the masses of astronauts can be determined using an oscillatory device known as an inertia balance that relies on springs rather than gravity for its restoring force. A 22.5 kg chair attached to a spring takes 1.30 s to complete one cycle of oscillation. With an astronaut sitting in the oscillating chair with feet...
