Now Gravitational constant G=6.7×10−11Nm2/Kg2 Mass of earth m1=6×1024kg Mass of object m2=1kg And , Distance between center r=Radius of earth of earth and object =6.4×106m Now,Putting these values in the above formula ,we get F=6.7×10−11×6×1024×1(6.4×106)2...
The acceleration due to gravity'g' for objects on or near the surface of earth is related to the universal gravitational constant 'G' as ('M' is the mass of the earth and 'R' is its radius): View Solution Exams IIT JEE NEET
G is the gravitational constant Answer and Explanation:1 Given data: {eq}h = 5000\ km {/eq} is the height of the satellite above the surface of the earth Constants to be used: Mass of the earth {eq}M =... Learn more about this topic: ...
So, Jupiter started migrating to the Sun, but when Saturn appeared there was a complicated gravitational effect which reversed the migration, and the planets moved further from the Sun. Thanks to Saturn, the giant planet Jupiter changed trajectory.所以，木星开始向太阳迁移，但当土星出现时，一个复杂...
The composition of the atmosphere is more or less constant with height to an altitude of about 100 km (60 miles), with particular exceptions being water vapour and ozone. The atmosphere is commonly described in terms of distinct layers, or regions. Most of the atmosphere is concentrated in ...
(1687). He pointed out that a cannonball shot at asufficientvelocity from atop amountainin a direction parallel to the horizon would go all the way around Earth before falling. Although the object would tend to fall toward Earth’s surface because ofgravitationalforce, itsmomentumwould cause ...
Why Isn't Earth's Rotation Constant? The speed of the Earth's rotation varies from day to day. One of the main factors are the celestial bodies surrounding us. For example, the Moon's gravitational pull causes tides and changes the Earth's shape, ultimately resulting in a lower rotational...
Gravitational attraction between density heterogeneities in the fluid core and mantle can exert a torque on the mantle, leading to changes in the length of the day (Jault and Le Mouël, 1989; Buffett, 1996a). The strength of the gravitational torque depends upon the size of the mass anoma...
