CEE Grand Mock Simulation — 01

1. A particle moves in a straight line such that its displacement at any time $t$ is given by $s = t^3 - 6t^2 + 3t + 4$ meters. What is the velocity of the particle when its acceleration vanishes?

2. If the error in measuring the radius of a high-yield spherical biological structure is exactly $2\%$, what will be the resulting total calculated error projection in determining its volume parameters?

3. Which among the following specific electronic orientation models matches the expected baseline ground state configuration rule of a Chromium atom ($Z = 24$)?

4. During a high-stress diagnostic situation, which specific endocrine organ cell structure secretes the primary flight-or-fight mechanism signals of epinephrine and norepinephrine?

5. Which primary compound or specialized receptor molecule acts as the vital recipient structure during the non-cyclic photophosphorylation track to capture terminal electrons ejected from Photosystem I ($PS\ I$)?

6. Look closely at the progress patterns: $7, 10, 8, 11, 9, 12, \dots$ What logical metric indexing value should fit next in the active progression line?
