<span>5 electrons because first shell can only have two electrons and second can hold up until 8</span>

If it had seven electrons then we know that the first energy lever has to have two and no more and so it would be 5 as you will only have 5 left. if you had more then 8 then there would be three but these not so your fine!! 5 electrons on other shell

A 0.5-kilogram ball is thrown vertically upward with an initial kinetic energy of 25 joules. Ap-proximately how high will the ba

tatuchka [14]

It's gravitational potential energy at the top will roughly equal it's kinetic energy when it was released (a little is lost to air resistance). Note this will assume the release point is zero potential energy. (we are free to define it that way, just letting you know). Gravitational potential energy is mgh.
mgh=25J
h=25J/(0.5kg x 9.81m/s^2) = 5.097m
So it goes about 5.1 meters above the point where it was released
