I heart from my friend that light is both wave and particle but i don't know that is true or not.
So can you guy tell me what light actually is?
And how light travel from the source and then to our eye?
Guy guy, i just learn a little bit about quantum physics and i know that electrons is not particles.
But i don't understand how it move.
By the way I am only a secondary school student.
If you explain it clearly and easy to understand i'll be very happy.
But thank you all for taking time to help me!
Negative temperatures could be used to create heat engines — engines that convert heat energy to mechanical work, such as combustion engines — that are more than 100-percent efficient.
I think that the speed of water would effect the bullet too.
Because if the water is stand still and the bullet move the water is move too (from the bullet view).
So if the water is move so it speed would increase or reduce (from the bullet view) make the friction would increase or reduce make...
