A, an iconic ion covalently bonded with a metal
Acceleration due to gravity on that planet is half than that of om earth ~
that is ~
And it's weight is equal to ~
now, As we know ~
here ,
- g = Acceleration due to gravity on that planet = 4.9 m/s²
let find the mass of stone ~
Mass of the stone is 100 kg ~
I hope it helped
Yes, this is accurate. While "dark matter" might exist, it is still more of a theory, it is not yet defined properly. As far as we truthfully know, the entire universe is just matter and energy.
As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy.
