Answer: Explanation:
If the net force on an object is doubled, its acceleration will double If the mass of an object is doubled, the acceleration will be halved .
If the measurement is in joules then you can push something or pull something as long as you are moving the object. Formula: f*n force times newtons
Pet rocks contain organic matter
Answer:
When the starting and ending points are the same, the total work is zero.
Explanation:
option ( D )correct
A force is said to be conservative when the work done by the force in moving a particle from a point A to a point B is independent of the path followed between A and B and is the same for all the paths. The work done depends only on the particles initial and final positions. And when the initial and final position in conservative field are same the work done is said to be zero.
during satellite motion we know that total energy is always conserved
so here we will have

here we know that


now at other position

now from above equation we have

now we have


so its kinetic energy will be 3500 MJ
