According to Kepler's third law of planetary motion, the mean distance D, in millions of miles, from a planet in our solar system to the sun is related to the time P, in years, that it takes for the planet to complete a revolution around the sun, and the relationship is D = 93P 2/3. It takes the planet Pluto 248 years to complete a revolution around the sun. What is the mean distance from Pluto to the sun? What is the mean distance from Earth to the sun? Give your answers to the nearest million miles. from pluto to sun _____ million miles from earth to sun _____ million miles
the weight, w, of an object varies inversely as the square of the distance, d, between the object and the center of Earth. If a man weighs 75kg on the surface of Earth, how much would he weigh 300km above the Earth's surface? (given the radius of the earth is approximately 6400km)
Assume the Earth is a uniform sphere with constant density. Let R represent the radius of the Earth and g be the acceleration due to gravity at the surface. At which location above the surface of the earth will the acceleration due to gravity be g/3? Check to see if the answer is correct or/and makes sense.
In January 2006 astronomers reported the discovery of a planet, comparable in size to the earth, orbiting another star and having a mass about 5.5 times the earth’s mass. It is believed to consist of a mixture of rock and ice, similar to Neptune. If this planet has the same density as Neptune 11.76 g>cm32, what is its radius expressed (a) in kilometers and (b) as a multiple of earth’s radius?
The ocean is not flat, because the Earth is curved. Take the radius of the Earth to be 6.38 × 103 km. How many meters lower will its surface be 32.0 km from the ship as measured along a line that is tangent to the surface of the Earth at the location of the ship?
The gravitational force exerted by the earth on a unit massat a distance r from the center of the planet is where M is the mass of the earth,R is its radius, and G isthe gravitational constant. Is F a continuous function of r ?
Assuming that the earth is a homogeneous spherical body with radius R, show that its meandensity? =3?/4???
Show that for eccentricity equal to one in Equation 13.10 for conic sections, the path is a parabola. Do this by substituting Cartersian coordinates, x and y, for the polar coordinates, r and , and showing that it has the general form for a parabola, x=ay2+by+c .
Calculate the effective gravitational field vector g at Earths surface at the poles and the equator. Take account of the difference in the equatorial (6378 km) and polar (6357 km) radius as well as the centrifugal force. How well does the result agree with the difference calculated with the result g = 9.780356[1 + 0.0052885 sin 2 0.0000059 sin2(2)]m/s2 where is the latitude?
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
The International Space Station (ISS) is a space station orbiting the earth above the ground. If the radius of the earth is 3,958.8 miles, mass of earth is 5.972 x 1024 kg, the period of the ISS at the orbit around the earth is 2.00 hours, can you calculate what is the distance from the ISS to the surface of the earth, in unit of miles? Use G=6.674 x 10-11 Nm2/kg2. Wirte answer in pure numbers.
Can I get an explanation of 4 and 5 with plugging the values (radius) in ? I’m stuck , It would help a lot ,Thank you!!
