Its equatorial radius is 6378 km, but its polar radius is 6357 km - in other words, the Earth is slightly flattened. Eratosthenes was measuring the polar radius, and his value (using the 0.15 km/stadium conversion) lies between the polar and equatorial values. 21.Complete the following sentence: Customers who owe money for goods or services purchased are called… Ответы [a] creditors [б]debtors [в] finances [г] merchant. 22.Complete the following sentence...Oct 21, 2018 · ☸️ 'g' refers to the acceleration due to gravity which acts on everything present on the earth. This is rate at which the earth attracts an object. ☸️ The equation for finding g is :-Where g is the acceleration due to gravity, capital g or G is the gravitation constant,. M is the mass of the planet and R is the radius of the planet. Question 1. The radius of the earth is 6400 km and g = 10 m/s².

If the earth were to suddenly contract to half of its present radius (without any external torque on it), by what duration would the day be decreased ? Assume earth to be perfect solid sphere of radius `(2)/(5)MR^(2)`. D 6. If the earth suddenly contracts to half of its radius, what would be the length of day. The radius of planet is R1 and a satellite revolves round it in a circle of radius R2. The time period of revolution is T. Find the acceleration due to the gravitation of the planet at its surface.Because of conservation of angular momentum, the earth's angular speed would quadruple if its mass was contracted into half its radius. I assume you mean that suddenly the earth's core becomes much dense and earth shrinks to smaller diameter without loss of mass or loss of angular momentum .Dec 01, 2015 · $\begingroup$ @brucesmitherson Ok,orbit velocity MUST be an escape velocity at the radius that planet orbits (for circular orbit). Any slight change will, technically, blows earth away or pulls earth towards the sun. So in a Earth-Sun system where anything else doesn't exist, 1% change in mass of the Sun results in catastrophe. $\endgroup$ – Jun 14, 2019 · If the radius of the earth contracts to half of its present value without change in its mass, what will be the new duration of the day? asked Apr 17, 2020 in Physics by Subodhsharma ( 86.1k points) class-12 Given: radius of earth shrink by 1/3.
