To calculate the gravitational force of attraction between two bodies of masses 40 kg and 80 kg separated by a distance of 15 m, we can use the formula derived from Newton's law of universal gravitation: F=G⋅m1⋅m2r2 Where:- F is the gravitational force of attraction,- G is the ...

Gravity is the force of attraction which exists between any two objects in the universe The force of attraction F Newtons between two masses d cm apart is given in the following table:What factor confirms that the fit is excellent? 相关知识点: 试题来源: 解析 r^2≈ 0.9999 is very close...
Gravity is a force of attraction that exists(存在) between any two objects in the universe. It makes planets go around the sun and creates stars and galaxies(银河系). Gravity is also what gives weight to objects on Earth and keeps us from floating away. It pulls everything towards the ...
6. Why does the author include the information that "The force of molecular attraction between oil and quartz or carbonate minerals is weaker than that between water and quartz or carbonate minerals."? O To help explain why petroleum behaves differently from water in bodies of sandstone and lime...
that gravity is not an attraction or a force. Instead, it's a consequence of objects bending space-time. A large object works on space-time a bit like how a large ball placed in the middle of a sheet affects that material, deforming it and causing other, smaller objects on the sheet ...
