- How would the density change on another planet?
Step by step
Solved in 2 steps
- What would Earth's surface gravity and escape speed be if the entire planet had a density equal to that of the crust (3000 kg/m³, say)?why is gravity not negative? (-9.8 m/s^2)Rockets are launched into space from Cape Canaveral in an easterly direction. Is there an advantage to launching to the east versuslaunching to the west? Explain.
- Calculate the acceleration due to gravity at the surface of earth. (radius of earth r = 6.4 × 106 m, G = 6.67 × 10-¹¹ Nm² / kg², mean density of the earth = 5.5 × 10³ kg/m³) 11The planet Saturn has an average radius of 9 Earth radii and a density of 0.7 g/cm3 (yes, less dense than water!). How many Earth radii must a moon remain beyond the center of this giant planet, if the moon is made of water ice (0.9 g/cm3)? (i) How many Saturn radii does this equal?The mass of the planet is approximately 74.8 times the mass of Jupiter. Calculate the average density of the planet. Give your answer in grams per cubic centimeter.
- The total mass of this planet's atmosphere may be higher than the Earth's but the gases present must be very lighter ones like hydrogen and helium. The escape velocity of the planet will be very high. Due to the high escape velocity the light gases were not able to escape and hence forming a thick atmosphere Is the escaping velocity for this planet greater or lower than that of the earth?The total mass of this planet's atmosphere may be higher than the Earth's but the gases present must be very light ones like hydrogen and helium. The escape velocity of the planet will be very high. Due to the high escape velocity, the light gases were not able to escape and hence forming a thick atmosphere Is the escaping velocity for this planet greater or lower than that of the earth?What is the gravity of Mars, if the mass of the planet is 6.39x1023kg and the radius of the planet is 3397.2 km? What problems would there be on a mission to Mars?
- If Earth were of uniform density( same mass/volume throughout), what would the value of g be inside Earth at half its radius?Do tides depend more on the strength of gravitational pull or on the difference in strengths?Explain.Most people today know that the ocean tides are caused principally by the gravitational influence of the Moon, and most people therefore think that the gravitational pull of the Moon on Earth is greater than the gravitational pull of the Sun on Earth. What do you think?
