For a planet twice as far away from the sun as the Earth, how much lower would its solar constant be?
The Sun is about 10.0 billion times brighter than the next brightest star, Sirius (as seen from Earth). How far would we have to be from the Sun for the Sun to be as bright as Sirius? We would have to be ___× 10 5th AU or _____light-years away from the Sun.
If the sun is about 150 Gm away from the Earth, what is the total power that hits the earth? You may assume that the Earth is a disk that faces the sun with a radius of 6378 km and the area is that of a circle of the same radius. (Answer in PW = 1e15 W with three sig figs)
A large asteroid of mass 60900kg is at rest far away from any planets or stars. a smaller asteroid of mass 8.0 x 10^2 kg, is in circular orbit about the first at a distance of 366 meters as a result of their mutual gravitational attraction. What is the speed of the second asteroid? Now suppose that the first and second asteroids carry charges of +2.68c and -2.68c. How fast would the second asteroid have to be moving in order...
The Earth moves in its orbit about the Sun at about 30 km/s. How far does it move in 4 minutes? Give the answer in km as an integer (whole number).
based on this how far away horizontally from Donald
would the balloon land?
2. Donald wants to throw a water balloon at his nemesis, Joe. Worried that he might get splashed by some of the water, he decides to throw it from a height of 200 m above Joe and some horizontal distance away. Given that his old age, he could only throw the water balloon with a strictly horizontal speed of 6 m/s.
A large asteroid of mass 71700 kg71700 kg is at rest far away from any planets or stars. A much smaller asteroid, of mass 830 kg,830 kg, is in a circular orbit about the large asteroid at a distance of 256 m256 m as a result of their mutual gravitational attraction. What is the speed ?2v2 of the second asteroid? ?2 m/sm/s Now suppose that the first and second asteroids carry charges of +1.68 C+1.68 C and −1.68 C,−1.68 C,...
or far away from it? How does the direction of the lines depend on the signo Question 1-4: Are the lines beginning or ending on a charge more dense Question 1-5: Summarize the properties of electric field lines. What does the number of lines signify? What does the direction of a line at each point in space Teat represent? What does the density of the lines represent?
f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...
1. All the planets orbit the Sun in the same direction. This is strong evidence that: Group of answer choices None of these is correct. We do not have any idea yet why the planets are orbiting in the same direction. the solar system resulted from the collision of two medium-sized stars. after the planets formed, collisions between them eventually caused them all to move in the same direction. the planets were formed elsewhere in the galaxy and were later...
