The right answer would be
-20t+ 80
Answer:
Explanation:
The negative only matters reallly if you are dealing with a 2d system. I could even define down as positive and up as negative. However, usually you are taught that down is negative. It really doesn't matter because a force is a force. It is only given a direction relative to another force or vector direction.
The current atomic model has a predicted area surrounding the nucleus where the electron could be located thanks to quantum physics, subatomic particles makes leaps through space, and an electron could even be a million miles from its nucleus.
So the correct option among the other answer choices are as follows: C.
Answer:
ω = B₀q/m
Explanation:
The centripetal force on the charge equal the magnetic force on the charge. (Since the trajectory is a circle). So, mrω² = B₀qv.
v = rω The speed of the charge and r = radius of path
mrω² = B₀qrω
ω = B₀q/m
The angular frequency ω = B₀q/m
