- While a meter is the fundamental unit of length, most distances traveled by humans are measured in miles or kilometers. Why do you think this is?I measured the angular separation of Jupiter's moons in arcminutes/arcseconds and converted this angle to radians. The conversion factor for degrees to radians was 57.3 degrees per radian. Which unit of measurement is larger? 1 degree or 1 radian?The y- axis is from 0 to 1200 (200, 400 ,600) thr x axis is 0.5 to 3 ( 0.5,1,1.5 )
- The radius of the earth is 6400 Km and the height of a person is 1.7m, how high can you stand to see how far the horizon is from you (going back in degrees after the arc)From a distance of 300 km above the surface of the Moon, what is the angular diameter in arc seconds of an astronaut in a space suit who has a linear diameter of 0.80 m as seen from above?The intensity of light from a central source varies inversely as the square of the distance. If you lived on a planet only half as far from the Sun as our Earth, how would Sun’s light intensity compare with that on Earth? How about a planet 10 times farther away than Earth?
- Sam is an astronomer on planet Hua, which orbits the distant star Barnard. It has recently been accepted that Hua is spherical in shape, although its exact size is unknown. While studying in the library, in the city of Joy, Sam learns that during equinox, Barnard is directly overhead in the city of Bar, located 1500.0 km north of his location. On the equinox, Sam goes outside and measures the altitude of Barnard at 83 degrees. What is the radius of Hua in km?friend are traveling the world and are currently in a city located precisely on the Earth's equator.

What keeps a satellite up in its orbit around the Earth?You and your friend are traveling the world and are currently in a city located precisely on the Earth's equator. You are staying in separate rooms at a fancy skyscraper hotel that is 50 floors tall. Your friend's room is several floors above yours. Your rooms are on the same side of the building and both of you have the same clear view of the horizon, which appears featureless and smooth because of a very flat desert. Through the window of your room, you watch the sunset over the smooth horizon from a height of 28 m above the ground, and you see the top of the Sun disappear at time t1 on your watch. In his room, your sees the Sun disappear at a later time t2, as measured in his watch, which is perfectly synchronized with yours. Assuming that the Earth has a radius of 6378 km and that it completes a full revolution around its axis in 23 hours, 56 minutes, and 4 seconds, determine the time interval friend watches the sunset from a height of 104m above the ground, and At = t2 – t1…The speed of light is exactly e = 299792458 m - s1. (Also written 299, 792, 458 m - s-1 or 2.99792458 × 10°m - s1. This is exact because it is the definition of the metre.) It takes light 8.3 minutes to get from the sun to the earth. Assuming that the earth's orbit is exactly circular (an approximation) and that its speed is constant, and using the data in this question, calculate the speed of the earth in its orbit around the sun in km · hr. Practise writing your conversions clearly using the 'multiply by 1' technique. Speed of the earth =_ km per hour. Write your answer in standard (not scientific) notation, i.e. without using exponents, and without using commas. However, remember to use the correct number of significant figures. (Hint: which is the least precise of the given data?) Do not include units.
