UniquackSmall-cohort testing

Uniquack.
Teach. Study. Remember. Connect.

A complete teaching and self-study platform—with an open AI layer through MCP.

Uniquack supports both sides of learning: teachers can prepare and respond to formal classroom evidence, while students can build an independent study workspace around their own questions, mistakes and practice.

Particle motion.pdf / Original illustrative material

Particle motion: how far did it actually travel?

A particle moves along the x-axis with velocity v(t)=(t−1)(t−3)e−t/2v(t)=(t-1)(t-3)e^{-t/2} meters per second, for 0≤t≤40\le t\le4. Its initial position is x(0)=2 mx(0)=2\,\mathrm{m}.

  1. Find all intervals on which the particle's speed is increasing. Justify your answer.
  2. Find the particle's position at t = 4.
  3. Find the total distance traveled. Show how changes in direction affect your calculation.

Not an official exam question. The full source is shown; the selected assignment task follows below.

AI proposal, not a reviewed answer.

Human review

Distinguish the proposed displacement from the total distance requested in part (c).

  • Check the source asks for total distance, not displacement or position.
  • Check the sign changes at 1 and 3 seconds against the velocity graph.
  • Check that the three path contributions add as magnitudes and the answer is in meters.

Split at 1 and 3 seconds. Subtract the negative middle integral and add both positive integrals. Total distance is 1.863 m; displacement is 0.857 m.

Original example response

0.857 m

The signed integral is treated as total distance, so backward travel cancels forward travel.

A useful hint

Where does the particle change direction?

Read the next hint

Between 1 and 3 seconds, velocity is negative. Does that part of the path stop counting?

In this example, 0.857 m is displacement. Total distance adds the path traveled in both directions: split at 1 and 3 seconds and add the three magnitudes.

I count each part of the path positively, so backward travel no longer cancels forward travel. Initial position changes the final position, not the total distance.

The signed integral is reported as distance instead of displacement.

-0.005 mol/L/s

The negative concentration-change slope is reported as the disappearance magnitude.

A useful hint

You calculated Δ[A]Δt\frac{\Delta[A]}{\Delta t}. How is the disappearance rate of a reactant defined?

Read the next hint

The concentration falls by 0.30 mol/L over 60 seconds. What does the minus sign in −Δ[A]Δt-\frac{\Delta[A]}{\Delta t} do to that negative slope?

Authored feedback

In this example, the concentration changes by -0.30 mol/L over 60 seconds. Its average disappearance rate is the positive magnitude: +0.005 mol/L/s.

What determines the reaction rate?

Student's private review

+0.005 mol/L/s

I separate the negative concentration-change slope from the positive disappearance magnitude. These three measurements alone do not establish the reaction order; the connecting lines are not a fitted rate law.

Narrated private revision. Not sent to the teacher.

Teacher's formal evidence

-0.005 mol/L/s

Concentration-change slope is confused with positive disappearance rate; reaction order has not been justified.

Next teaching move

The formal -0.005 mol/L/s response suggests a sign-definition mix-up. Ask for concentration-change rate and disappearance rate side by side, then ask what additional concentration-time or initial-rate evidence a rate-law conclusion would need.

Selected context: this question and its formal assignment response.

Use the selected concentration measurements and formal -0.005 mol/L/s response to draft a two-part check-in on rate signs and evidence sufficiency. Do not infer a reaction order from these points alone.

Read the illustrative returned plan

Draft check-in: calculate Δ[A]Δt\frac{\Delta[A]}{\Delta t} and −Δ[A]Δt-\frac{\Delta[A]}{\Delta t} for 0 to 60 seconds, naming the quantity and mol/L/s unit each time. Then ask whether three measurements establish reaction order and what additional measurements or model comparisons would support that conclusion. Review this draft before assigning it.

Returns as a draft for review, not an assigned assessment or approved Blueprint.

Student: a personal review note

Selected context: this question and the learner's chosen attempt.

Explain the sign in my chosen -0.005 mol/L/s disappearance-rate answer. Start with the definition, and keep the rate calculation separate from any claim about reaction order.

Read the illustrative private note

For the disappearance of A, use −Δ[A]Δt-\frac{\Delta[A]}{\Delta t}. The sign of the concentration change is not the sign of the disappearance magnitude. My private correction is +0.005 mol/L/s; the original formal response remains unchanged.

How does concentration change transport?

Two equal-pressure compartments are separated by a membrane permeable to water but not sucrose. Side A contains 0.10 mol/L sucrose. Side B contains 0.40 mol/L sucrose.

  1. Predict the initial direction of net water movement.
  2. Explain what would change if the membrane also allowed sucrose to cross.

Not an official exam question. The full source is shown; the selected assignment task follows below.

A / 0.10 MB / 0.40 MDots: sucrose. Arrows: water. Predict net flow.
Initial equal-pressure state. Dots represent sucrose; the membrane admits only water.

Side A: 0.10 mol/L sucrose. Side B: 0.40 mol/L sucrose.

Water can cross the membrane; sucrose cannot.

AI-proposed draft

Two equal-pressure compartments are separated by a membrane permeable to water but not sucrose. Side A contains 0.10 mol/L sucrose. Side B contains 0.40 mol/L sucrose. Predict the initial direction of net water movement. Explain what would change if the membrane also allowed sucrose to cross.

A to B

AI proposal, not a reviewed answer.

Human review

Check the membrane legend and qualify A-to-B flow as initial net water movement.

  • Check the source has equal initial pressure, A at 0.10 mol/L and B at 0.40 mol/L sucrose.
  • Check the legend distinguishes permeable water from sucrose, which cannot cross.
  • Check the answer says initial net water movement from A to B, not one-way or unlimited flow.

Reviewed example question

A to B initially. If sucrose can also cross, it initially diffuses from B to A; the changing gradients alter water movement.

With equal initial pressure and impermeant sucrose, net water moves from dilute solution A toward concentrated solution B. This is the initial direction, not a claim of unlimited flow.

B to A

Water movement is confused with movement down the sucrose concentration gradient.

Which substance can cross the membrane in this question?

Read the next hint

At equal initial pressure, which side has the more dilute solution? Predict the net movement of water, not sucrose.

Authored feedback

Water can cross; sucrose cannot. With equal initial pressure, initial net water movement is from dilute A toward concentrated B. Individual water molecules still move in both directions.

How does concentration change transport?

Student's private review

Water can cross; sucrose cannot. With equal initial pressure, initial net water movement is from A toward B.

I identify the moving substance before using a concentration comparison. Water moves both ways, with initial net movement from A to B; sucrose stays on its side. This is not a claim of unlimited flow or of every water molecule moving one way.

Narrated private revision. Not sent to the teacher.

Teacher's formal evidence

B to A

The response confuses water movement with solute movement and leaves the changed-permeability question unanswered.

Next teaching move

From the formal B-to-A response, ask which substance can cross, then contrast water movement with the initial net movement of sucrose if the membrane also became permeable to it. Use the formal response, not the private revision, to choose the follow-up.

Keep both fictional perspectives visible and ensure the expected comparison does not overclaim outcomes for every worker.

  • Identify a shared topic: both fictional excerpts mention paid hours or pay.
