Engineers and science fiction writers have proposed designing space stations in the shape of a rotating wheel or ring, which would allow astronauts to experience a sort of artificial gravity when walking along the inner wall of the station's outer rim. Imagine one such station with a diameter of 126 m, where the apparent gravity is 3.90 m/s2 at the outer rim. How fast is the station rotating in revolutions per minute? What If? How fast would the space station have to rotate, in revolutions per minute, for the artificial gravity that is produced to equal that at the surface of the Earth, 9.80 m/s2?
Here, (G = 6.67×10−11N m2/kg2) is the universal gravitational constant, (M) is the mass of the object,and (r) is its radius. For example, the mass of the Earth is (M = 6×1024kg) and the radius is (r = 6.4×106m). Thus, the surface gravity of Earth is:g=(6.67×10−11×6×1024(6.4×106)2)m/s2= 9.8 m/s2ObjectMassRadiusMercury3.3×1023kg2.4×106mVenus4.9×1024kg6.1×106mMars6.4×1023kg3.4×106mJupiter1.9×1027kg7.0×107mSaturn5.7×1026kg5.8×107mUranus8.7×1025kg2.5×107mNeptune1.0×1025kg2.5×107m ProcedureFor each of the planets listed above, compute the surface gravity in m/s21
An object of mass mm is launched from a planet of mass MM and radius RR. a) Derive and enter an expression for the minimum launch speed needed for the object to escape gravity, i.e. to be able to just reach r=∞. b) Calculate this minimum launch speed (called the escape speed), in meters per second, for a planet of mass M=2.73×1023kg and R=86.2×103km.
an effective way to create artificial gravity is through the use of a rotating cylinder, as shown in the figure. Humans walk on the edge of the cylinder which is sufficiently large (diameter of 3435 meters) that its curvature is not readable noticeable to the inhabitants. Once the space station is rotating at the necessary speed to create an artificial gravity of 1g how many minutes would it take to make one revolution
What is the gravitational force between two masses (m1 = 4 Kilograms and m2 -= 8 Kilograms) that are separated by a distance of 17 e meters? Express your answer as a number (rounded to one significant figure) and then the exponent of 10...for instance, express 3 x 10? as 3 and 2, express 5.3 x 10° as 5.3 and -3
On planet Q, g = 2.24 m/s^2, If the mass of planet Q is 8.96 x 10^21kg, what is the radius of planet Q. G = 6.67 x 10^-11N-(m/kg)^2
In recent years, astronomers have found planets orbiting nearby stars that are quite different from the planetsin our solar system. Kepler-12b has a diameter that is 1.7 times the diameter of Jupiter and has only 0.43 timesthe mass of Jupiter. Calculate the value of the acceleration due to gravity g at the surface of this large, lowdensity world?(See Table of Astronomical Information on the inside back cover of the text)
The free-fall acceleration on the surface of a fictional planet is about 1/7 that on the surface of the Earth.. The radius of the planet is about 0.68RE (where we use the symbol RE = Earth’s radius). Find the ratio of their average densities, ρp/ρE. Where RE = 6,378 km.
At what height (in km) above the surface of Earth would the gravitational acceleration be 8.3 m/s^2?
Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?
Assume the earth's mass is 85.47 x 1025 kg, and radius is 51.93 x 103 miles, what would be the gravitational acceleration on such an planet in unit of m/s2? Use G=6.67x 10 -11 Nm2/kg2.
For a planet of uniform density, how would the magnitude of the gravitational field halfway to the center compare with the field at the surface?
