AC HPAT Physics Exam Solved 100% Correct!! DIstance · Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement · Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position. Position · Position is a place where someone or something is located or has been put. In physics, position is usually a number on an axis. ... Position is a vector, because direc...

A car starts from rest and in ten seconds is moving at 40 m/s. What is the car's acceleration? correct answers 4.0 m/s2 An object, accelerating from rest at a constant rate, travels over 28 m in 11 s. What is its final velocity? correct answers 5.1 m/s A car comes to a stop over a distance of 30.0 m after the driver applies the breaks. If the car decelerates at a constant rate of 3.50 m/s2, what was the car's original speed? correct answers 14.5 m/s A stone is thrown straight up. ...

The instantaneous velocity of point P is: A. → B. ← C. ↑ D. « E. zero - CORRECT ANSWER - E. zero

1. mass specific metabolic rate is O2 consumption per mass unit per time 2. what if we assume living organisms are isometric 3. mass specific metabolic rate vs whole rate+graphs 4. how much O2 per mass per unit for large vs small animals, why do elephants have big ears Ans-1. VO2/Mb=0.676(Mb)^-0.25 2. heat loss ∝ SA & metabolism ∝ mass: VO2/Mb ∝ (Mb)^-1/3 small animals have more O2 per mass per unit -increase mass specific metabolic rate if whole metabolic rate decrease -graphs ...

OCR A A-LEVEL PHYSICS PAPER 1(LATEST 2025/2026) STUDY GUIDE WITH COMPLETE SOLUTIONS Displacement - -The distance travelled in a particular direction - it is a vector with magnitude and direction. Instantaneous Speed - -The rate of change of distance at a specific moment in time - change in distance divided by an infinitesimal interval of time. Average Speed - -The rate of change of distance calculated over a complete journey Velocity - -A vector quantity equal to the rate of change of d...

Fundamental SI units - Answer kilogram (kg), metre (m), second (s), ampere (amp), mole (mol), kelvin (K) Random error - Answer An unpredictable and largely uncontrollable uncertainty. (Examples include human reaction time and other forms of human measurement.) (Random errors can be reduced by taking the average of repeated measurements.) Systematic error - Answer An error that occurs on all measurements. (An example is a zero error on a scale.) (Systematic errors can NOT be reduce...
