D.
The gravitational of a body is possessed by the body due to the virtue of its position.
The formula for gravitational potential energy is,
P.E = mgh joules
Substituting the values
196*9.8*250= 49k
Given:
The mass of each sphere is
![m_1=m_2\text{= 25 }kg](https://tex.z-dn.net/?f=m_1%3Dm_2%5Ctext%7B%3D%2025%20%7Dkg)
The distance between the two spheres is r = 2 m
To find the gravitational force that one sphere exerts on the other.
Explanation:
The gravitational force is caculated by the formula
![F=G\frac{m_1m_2}{r^2}](https://tex.z-dn.net/?f=F%3DG%5Cfrac%7Bm_1m_2%7D%7Br%5E2%7D)
Here, the universal gravitational constant is
![G=\text{ 6.67}\times10^{-11}Nm^2kg^{-2}](https://tex.z-dn.net/?f=G%3D%5Ctext%7B%206.67%7D%5Ctimes10%5E%7B-11%7DNm%5E2kg%5E%7B-2%7D)
Substituting the values, the gravitational force will be
![\begin{gathered} F=\frac{6.67\times10^{-11}\times25\times25}{(2)^2} \\ =\text{ 1.04}\times10^{-8}\text{ N} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20F%3D%5Cfrac%7B6.67%5Ctimes10%5E%7B-11%7D%5Ctimes25%5Ctimes25%7D%7B%282%29%5E2%7D%20%5C%5C%20%3D%5Ctext%7B%201.04%7D%5Ctimes10%5E%7B-8%7D%5Ctext%7B%20N%7D%20%5Cend%7Bgathered%7D)
Final Answer: The gravitational force that one sphere exerts on the other is 1.04 x10^-8 N.
Answer:
venus
Explanation:
its small and still its the hottest since it has carbon 4 oxide in its atmosphere
Steaming the egg
The heat is conduction through the pan and into the water
There is convection current in the water and the pot
The heat is radiated from the water to the egg
