What is density? What is xoilac tv trực tiếp bóng đá hôm nay formula for calculating density?
Density (also known as mass density) is a measure of xoilac tv trực tiếp bóng đá hôm nay amount of mass contained within a unit volume of a substance.
Below are xoilac tv trực tiếp bóng đá hôm nay formula for calculating density and xoilac tv trực tiếp bóng đá hôm nay average density of a substance:
xoilac tv trực tiếp bóng đá hôm nay formula for calculating density is:
D = m / V
Where:
- D is density (unit: kg/m³ or g/cm³)
- m is xoilac tv trực tiếp bóng đá hôm nay mass of xoilac tv trực tiếp bóng đá hôm nay object (unit: kg or g)
- V is xoilac tv trực tiếp bóng đá hôm nay volume (unit: m³ or cm³).
xoilac tv trực tiếp bóng đá hôm nay formula for calculating average density:
xoilac tv trực tiếp bóng đá hôm nay average density of any object is calculated by dividing its mass by its volume, commonly denoted by p:
p = m / V
Where:
p: Average density (unit: kg/m³ or g/cm³)
m: Mass of xoilac tv trực tiếp bóng đá hôm nay object (unit: kg or g)
V: Volume of xoilac tv trực tiếp bóng đá hôm nay object (unit: m³ or cm³).
Table of density of some substances:
| Solid | Density (kg/m³) | Liquid | Density (kg/m³) |
| Lead | 11300 | Mercury | 13600 |
| Iron | 7800 | Water | 1000 |
| Aluminum | 2700 | Gasoline | 700 |
| Rock | (approx.) 2600 | Kerosene | (approx.) 800 |
| Rice | (approx.) 1200 | Cooking oil | (approx.) 800 |
| Good wood | (approx.) 800 | Alcohol | (approx.) 790 |

What are xoilac tv trực tiếp bóng đá hôm nay educational goals for grade 10 Physics in Vietnam?
According to xoilac tv trực tiếp bóng đá hôm nay provision in Section III of xoilac tv trực tiếp bóng đá hôm nay General Education Program for Physics issued together withCircular 32/2018/TT-BGDDT, xoilac tv trực tiếp bóng đá hôm nay educational goals for upper secondary school physics are as follows:
- Along with other subjects and educational activities, help students form and develop key qualities and competencies specified in xoilac tv trực tiếp bóng đá hôm nay overall program.
- Help students develop physics competencies, as evidenced by xoilac tv trực tiếp bóng đá hôm nay following:
+ Acquire essential general knowledge and skills about: physical system models; energy and waves; force and fields;
+ Apply certain scientific process skills to explore and solve problems from a physics perspective;
+ Apply certain knowledge and skills in practice, behave with nature in a way that aligns with xoilac tv trực tiếp bóng đá hôm nay demands of sustainable social development and environmental protection;
+ Recognize personal abilities and strengths, orient careers and make plans for study and training to meet career orientation requirements.
What are regulations on evaluation of xoilac tv trực tiếp bóng đá hôm nay educational outcome for grade 10 Physics in Vietnam?
Based on Section VII of xoilac tv trực tiếp bóng đá hôm nay General Education Program for Physics issued together withCircular 32/2018/TT-BGDDT, xoilac tv trực tiếp bóng đá hôm nay evaluation of educational outcomes for grade 10 Physics is as follows:
(1) General Orientation
- xoilac tv trực tiếp bóng đá hôm nay goal of evaluating educational outcomes is to collect truthful, prompt, and valuable information about xoilac tv trực tiếp bóng đá hôm nay level of achievement required and xoilac tv trực tiếp bóng đá hôm nay progress of students; thereby guiding learning activities and adjusting teaching activities.
- xoilac tv trực tiếp bóng đá hôm nay basis for evaluation in physics is xoilac tv trực tiếp bóng đá hôm nay required competencies regarding general competencies and physics competencies specified in xoilac tv trực tiếp bóng đá hôm nay overall program and xoilac tv trực tiếp bóng đá hôm nay physics program. xoilac tv trực tiếp bóng đá hôm nay evaluation subjects are xoilac tv trực tiếp bóng đá hôm nay learning, training process, and student products through studying physics.
- To evaluate student competency, it is necessary to design scenarios where problems require solving, helping students demonstrate their competencies. Furthermore, it is important to identify and choose evaluation methods, tools, and criteria appropriately.
(2) Focus and Form of Evaluation
- xoilac tv trực tiếp bóng đá hôm nay focus of evaluating learning outcomes in physics is xoilac tv trực tiếp bóng đá hôm nay competency to recognize problems, solve problems, and practice and experimental skills, specifically recognizing core concepts about:
+ Physical system models, energy and waves, forces, and fields, and related professions in physics;
+ Experimental skills, practical skills, scientific inquiry, and applying learned concepts to explain simple physical phenomena, initially solving some practical problems, and aptly interacting with xoilac tv trực tiếp bóng đá hôm nay natural environment.
- It is necessary to coordinate reasonably between teacher assessment with peer and self-assessment by students;
- Evaluation through observation of group activities inside and outside classrooms, observation of practical and experimental manipulations in physics, analysis of presentations;
- Evaluation through verbal questioning and evaluation through exercises, tests, notebooks, practical result reports, project study results, research work results, and other learning portfolios;
- Evaluation in xoilac tv trực tiếp bóng đá hôm nay form of essays combined with objective tests, combining process assessment, summary assessment, regular and periodic assessments.
