For Density of materials, which option correctly completes the kilogram density calculation calculation in the objective: Apply MS 1c and MS 3c skills when using standard form, significant figures and rearranging the density equation.?

The correct answer is The 2 kg mass is divided by 0.004 m?, so the density is 500 kg/m?. (Density kilogram density calculation)..

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: For Density of materials, which option correctly completes the kilogram density calculation calculation in the objective: Apply MS 1c and MS 3c skills when using standard form, significant figures and rearranging the density equation. The correct response is The 2 kg mass is divided by 0.004 m?, so the density is 500 kg/m?. (Density kilogram density calculation)., because density links mass and volume, so the answer must preserve which quantity is being calculated. In Density of materials, the marking point should connect directly to apply MS 1c and MS 3c skills when using standard form, significant figures and rearranging the density equation. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Changes of state and the particle model, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 103 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
