1.) 1st 2 quantom numbers (n,l) of the highest energy e- in the ground state of Sc^3+ are 3,1..true or false

my work is: Sc = [AR] 4s2 3d1 so ..
Sc^3+ = [AR] 3p6

how is it equal to 3,1?

2.) I don't understand the difference between ground and excited states. All i know is that when an e- gets excited, it moves to a higher (excited state).

if the e- config for Cr = 1s2 2s2 2p6 3s2 3p6 4s2 3d4..what would the excited state be?

A wheel 2.00 m in diameter lies in a vertical plane and rotates with a constant angular acceleration of 4.00 rad/s. The wheel starts at rest at t = 0, and the radius vector of a certain point P on the rim makes an angle of 57.3 with the horizontal at this time. At t = 2.00 s, find (a) the angular speed of the wheel, (b) the tangential speed and the total acceleration of the point P, and (c) the angular position of the point P

In a ballistics test, a 25 g bullet traveling horizontally at 1200 m/s goes through a 30 cm thick 350 kg stationary target and emerges with a speed of 850 m/s. The target is free to slide on a smooth horizontal surface.


(a) How long is the bullet in the target?

(b) What average force does it exert on the target?
N (magnitude only)

(c) What is the target's speed just after the bullet emerges?
m/s

We just finished a series of experiments in the lab where we tried several different settings on the oscilloscpe (changing time, waveform, amplitude, etc), but we were not told how to determine this during the class.
However, an answer to this question is required in our lab report.

Thanks in advance, I will choose a best answer!

Given that the limiting velocity in our universe is the speed of light and tachyons move at greater than light speed and can never slow down to light speed, therefore being doomed to exist (if at all) forever beyond our event horizon how can their existence ever be proved? And if proof of their existence is not possible then is belief in their existence similar in kind to a belief in God, i.e., requiring faith? So just what is the role of tachyons in contemporary physical theory?
