<p>i said parabola, because i thought it was with a*t^2. Which is a parabola</p>

<p>parabola but i heard that best fit lines can’t be bent so idk</p>

<p>What did you guys answer for the question about Newton’s Third Law.
Some of the choices were: 1) Act on same object 2) Act on different objects… I said acts of different objects</p>

<p>What about the question about the induction. Some of the choices were like they’re both at the same electric potential, or their net charge is positive or their net charge is negative…</p>

<p>the best fit line was different from the scatterplot problem right</p>

<p>any other questions u guys remember lol</p>

<p>For the question where three forces on the triangular block, does no movement imply that the vector sum of torques and forces equal zero or does it mean that it does not linearly translate?</p>

<p>Willb7 => yes different from the scatterplot</p>

<p>what was the answer to the question which makes a sound more distinct choices were: frequency, timbre, resonance, beat</p>

<p><a href=“timbre - Google Search”>timbre - Google Search;

<p>which one depended on the fundamental frequency was it beats?</p>

<p>I think so</p>

<p>was the last 2 things frequency question quality of the sound (when it mentioned how the mediums were different but other things were the same)</p>

<p>Isnt fundamental frequency resonance and interference beats?</p>

<p>@Mathematical‌ I do know that the current is constant through all components in a series circuit, but how would the current physically pass through those wires? </p>

<p>@rafaelesf‌ For the Newton’s third law question, I said they act on the same object and for the induction one, I put net positive charge (on the left) because the negative wire was to the left of the sphere. </p>

<p>@blabberbot‌ what did you put for the triangular block question? </p>

<p>I believe if two instruments have the same frequency, its the quality (timbre) that makes the difference. </p>

<p>I’ll only directly answer the Newtons law question because it was a reused question from the only publicly release physics test, it was they act on different objects: I push on a wall the wall pushes back on me.</p>

<p>Net torque and net force must be zero in order for an object to be completely at rest(assuming velocity is zero).</p>

<p>Only a few more days until scores are out… [-O< </p>

<p>yay</p>
