Study Notes
Mentor and Test Overview
- This booklet is for self-study and to practice answering multiple-choice questions on topics typically covered in university admission tests.
- The booklet requires reading pages out of sequence.
- Starts with the first question, read the text, and choose an answer then go to the page indicated at the end of the answer.
- If the answer is correct, confirmation and additional information are provided.
- If incorrect, an explanation of why it's wrong is given.
- Physical science covered includes mechanics, optics, thermodynamics, and electromagnetism.
- Chemical Science includes matter structure, chemical symbols, stoichiometry, organic chemistry, solutions, and oxidation-reduction.
- Questions and explanations are mixed randomly, with a manual directing to the correct page.
- Answering incorrectly indicates a gap in knowledge/skill, requiring further study and repetition of the section involved.
- Correct answers indicate sufficient knowledge, but might still require further theory review or exercises to build experience.
- The method is inspired by a book from the 1960s, emphasizing individual cognitive experiences in learning.
Test Content
- Mechanics involves scalar and vector quantities, measurement units, and fundamental physics.
- Basic physics entities are addressed such as displacement, velocity, acceleration, mass, momentum, force, weight, work, and power.
- Laws of inertia, Newton's laws, and action-reaction principles are also included.
- Optics covers geometric principles, reflection, refraction, refractive index, prisms, concave and convex mirrors/lenses and the use of lens systems.
- Thermodynamics includes temperature, heat, specific heat, expansion, ideal gas equations, and basic thermodynamic principles.
- Electromagnetism includes electrostatics (Coulomb's law, electric fields, capacitors, potential difference/voltage) and magnetostatics (electric current, Ampère's/Lentz's/Faraday's laws, Ohm's/Joule's laws, magnetic fields).
- Electromagnetic radiation is also needed.
- The structure of matter involves atoms and molecules, including basic atomic constituents, the periodic table, ion compounds, and characteristics like water and air.
- Chemical symbols, formulas, and equations are assumed to have been learned.
- Stoichiometry requires knowledge of moles and calculations.
- Organic chemistry includes the simplest carbon compounds.
- Solutions include acid-base systems and pH.
- Oxidation-reduction covers basic oxidation and reduction and combustion reactions.
Quesito 1 (Question 1)
- Option A is incorrect because carbon abundance is not the sole requirement for it to be important.
- Carbon is the element that forms the most chemical compounds with itself and other elements.
Quesito 2
- If tension is connected to lamps, you need to know about circuits
- If power is multiplied by time, you will get energy
Quesito 3
- Option B The electrical resistance depends on the temperature
- In gas, mass remains is the only consistent variable
Quesito 4
- The mole ratio relates to stoichiometric ratios
- Oxygen in gas form is a molecule
Quesito 5
- Need to clarify the type for electric charge
Quesito 6
- The weight is what makes the slope work, so test that calculation to prove
Quesito 7
- If one half or another is halved, then speed will remain constant, will it seem?
Quesito 8
- The radius of trajectory is proportional to velocity
Quesito 9
- The prism is used because energy and light cannot escape one another
Quesito 10
- Be able to discriminate a different result with temperatures
Quesito 11
- There's something definitely rotational
Quesito 12
- Water is a noncompressible liquid and flows with force; what other way can the question be done?
Quesito 13
- One is on the right path yet there are errors to the maths
- Think about the period of time if it's a kilometer
Quesito 14
- You can't think of something at all
Quesito 15
- Three that remain in the parallel state
Quesito 16
- It's really not right, so one would ask yourself what is going wrong?
Quesito 17
- They're doing more but it is no such thing
