A ball is rolling across the floor. Every 3 seconds it travels 12 meters. Its speed, therefore, is 36 m/s. Is this problem solve
kirill [66]
No because you are supposed to do this

d = t)v
T for time and V for velocity or acceleration so what you do is take the two numbers

D= 3/12 it goes 12 meters every 3 seconds so you devide 12/3
12 \div 3 = 4
So for every second the ball roles 4 meters!
Hope this helps! :)

Why is cyanide ion negatively charged?
Bogdan [553]
The cyanide is CN^{-}
A carbon atom has 4 valance electrons and nitrogen has 5. Below is a Lewis-dot-structure of cyanide.
:N≡C.
The carbon atom is still one electron short of having a full octet and so it will seize another electron from almost anything, making the cyanide ion negative and whatever it took the electron from it now positive.
