Density = Mass / Volume
Density of stone = 100 / 10 = 10 g/mL
If the density is higher than water, then the object will sink. If the density of the object is lower than water, then the object will float.
Since the density of the rock is 10g/mL and the density of the water is 1g/mL, the stone will sink.
The speed of electromagnetic waves in a vacuum is the same as the speed of light. It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Hope this helps you (:
The answer is; non-metals have a high ionization energy
This means that it would take more energy to dislodge an electron from the valence orbital than it would take to do the same to a metal atom. Therefore it would be easier to share electrons for non-metals while it would be easier to lose an electron for metals to reach a stable electron configuration.
Kinetic energy because the ball is in motion or moving with energy behind it... kinda like when you shoot a gun, the bullet is fired out of the muzzle with kinetic energy ( Punch ) and the bullet goes through a wall or something. Sorry but my math skills aren't very good to give complex calculations but I would recommend that you maybe talk to some of the top ranking math guys on the website. Maybe they can give you better help...
Anyways, I hope I have been helpful to you.
