<p>They look right mostly right, (as in, they coincide with what I got). Except for a couple:</p>
<p>3e: the KE one looks somewhat like a cosine wave, since it is oscillatory (SHM), it is sinusoidal. The acceleration is like a sine wave - starts +, ends -.</p>
<p>6b: I didn’t realize this at first, but there is an equation i found at [Forces</a> between currents.](<a href=“http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/wirfor.html]Forces”>Forces between currents.) to get it. I put what you put, so hopefully they’ll accept both answers.</p>
<p>7c: ionization energy is the first ionization, so from n=4 to n= infinity. That is, I believe, 19 eV.
7d: I thought that it would move it to n=2, since it has enough energy to make that phase change but no more. My teacher never taught this, so I self-studied it.</p>
