Cost of a structural engineer. any one know how much it would cost to get a structural engineer to check my cottage before I start to do restoration work on it, the cottage was build 1900 thanks. Best Answer. Hi. If the engineer is just doing a check then it can vary across the country, but i would say Â£200 -Â£500.
Since the distances are so large, we usually express them in Astronomical Units (AU). (An AU is the average distance from Earth to the Sun, about 150 million kilometers or 93 million miles.) The table below lists the distance of each planet from the Sun in AU. (Numbers were taken from this page.)
They are traveling over a thousand miles an hour. At 38Â° latitude we are traveling about 820 miles per hour. That is quite impressive but it pales in comparison with the orbital speed of the Earth, The average distance of the Earth from sun is 93.5 million miles. This means that in 365.25 days the Earth travels 587.5 million miles. This works out to about 67 thousand miles per hour. This is the speed we travel 24 hours a day, 365.25 days a year. The orbital velocity is 2ÏR/T where R is the average radius of the orbit and T is the length of the year. The orbital velocity of a planet relative to that of Earth's is then the relative radius divided by the relative length of the year.
