All-Russian test works (VPR) are final tests organized in individual academic subjects to assess the level of training of schoolchildren, taking into account the requirements of federal state educational standards. Their organization provides for a unified schedule, the use of unified assignment texts and unified assessment criteria.
VPRs are not an analogue of the state final attestation. They are held at the regional or school level.
The results can be used to formulate programs for the development of education at the level of municipalities, regions and the country as a whole, to improve the methodology of teaching subjects in specific schools, as well as for individual work with students. VLOOKUP results do not affect obtaining a certificate and transfer to the next class. Rosobrnadzor does not recommend educational organizations use the results of VLOOKUP to assign annual marks to students.
This manual fully complies with the federal state educational standard (second generation).
The book contains 10 options for typical tasks of the All-Russian verification work(VLOOKUP) in physics for 11th grade students.
The collection is intended for 11th grade students, teachers and methodologists who use standard tasks to prepare for the All-Russian test work in physics.

VLOOKUP in physics grade 11 options with answers 2018
This test is optional and is carried out in 2018 by the decision of the school.
Testing work in physics includes 18 tasks, it takes 1 hour 30 minutes (90 minutes) to complete it. Participants in VLOOKUP in physics are allowed to use a calculator.
The work tests the assimilation of all sections of the basic level physics course: mechanics, molecular physics, electrodynamics, quantum physics and elements of astrophysics.
While completing VLOOKUP tasks, eleventh graders must demonstrate an understanding of the basic concepts, phenomena, quantities and laws studied in the physics course, the ability to apply the knowledge gained to describe the structure and principles of operation of various technical objects or to recognize the studied phenomena and processes in the surrounding world. Also, within the framework of VLOOKUP, the ability to work with textual information of physical content is tested.
Here the following skills are tested: to group the learned concepts; find definitions of physical quantities or concepts; recognize a physical phenomenon by its description and highlight essential properties in the description of a physical phenomenon; analyze the change in physical quantities in various processes; work with physical models; use physical laws to explain phenomena and processes; build graphs of the dependence of physical quantities, characterizing the process according to its description, and apply laws and formulas for calculating quantities.
At the beginning of the work, nine tasks are proposed that test the graduates' understanding of the basic concepts, phenomena, quantities and laws studied in the physics course.
The next group of three tasks checks the graduates' development of methodological skills. The first task is built on the basis of a photograph measuring instrument and evaluates the readings taking into account the specified measurement error. The second task tests the ability to analyze experimental data presented in the form of graphs or tables. In the third task from this group, it is proposed to independently plan a simple study and describe its implementation based on a given hypothesis.
Further, a group of three tasks is proposed that test the ability to apply the knowledge gained to describe the device and principles of operation of various technical objects. The first task invites graduates to determine the physical phenomenon that underlies the principle of operation of the specified device (or technical object).
This is followed by two contextual tasks. They offer a description of a device or a fragment from the instructions for using the device. Based on the available information, graduates need to identify the phenomenon (process) underlying the operation of the device and demonstrate an understanding of the main characteristics of the device or the rules for its safe use.
The last group of three tasks tests the ability to work with textual information of physical content. As a rule, the proposed texts contain different kinds graphic information (tables, schematic drawings, graphs). Tasks in the group are built on the basis of testing various skills in working with the text: from questions on the selection and understanding of information presented in the text in an explicit form, to tasks on the use of information from the text and existing knowledge.
The manual presents 20 options for testing in physics for 7th grade students. Each test paper contains 10 tasks that cover all the main topics of the physics course in the 7th grade of general education organizations. All tasks are given answers and a detailed grading system for their implementation. The workshop is necessary for 7th grade students, teachers and methodologists who use typical tasks to prepare for the All-Russian test work.
Testing work includes 10 tasks, for which 1 lesson is allocated (45 minutes). Fill out the answers in the text of the work according to the instructions for the tasks. If you write down an incorrect answer, cross it out and write down the correct one next to it.
When performing work, it is allowed to use a calculator.

Induction cookers
There is an inductor coil under the glass-ceramic surface of the induction hob. An alternating electric current flows through it, creating an alternating magnetic field. Eddy or induction currents are induced in the bottom of the dishes, which heat the bottom, and from it the food placed in the dish. Frequency alternating current in the inductance coil is 20-60 kHz, and the higher it is, the stronger the eddy currents in the bottom of the cookware.
Unlike a conventional gas stove, there is no heat transfer from the bottom up, from the burner through the glass-ceramic surface to the cookware, which means there is no heat loss. In terms of the efficiency of using the consumed electricity, the induction cooker compares favorably with all other types of stoves: heating is faster than on a gas or conventional electric stove.
Induction cooker device:
1 - dishes with a bottom made of ferromagnetic material;
2 - glass-ceramic surface;
3 - insulation layer;
4 - inductor
Induction hobs require the use of metal cookware with
ferromagnetic (a magnet must be attracted to the cookware). And the thicker
bottom, the faster heating occurs.
14. What physical phenomenon underlies the operation of an induction hob?
The phenomenon of electromagnetic induction
(or electromagnetic induction)
15. Choose from the list provided two correct statements and write down the numbers under which they are indicated.
1) The action of an induction cooker is based on the action of a magnetic field on a current-carrying conductor.
2) Heating of food in a cookware on an induction cooker is associated with the thermal effect of an electric current.
3) The induction current that heats the cookware depends on the frequency of the alternating current in the inductor.
4) Bottom of cookware for induction cookers can be made of glass.
5) Heating efficiency for conventional electric stove higher than that of induction.

solar system
The central object of the solar system is the star Sun. The overwhelming part of the entire mass of the system is concentrated in the Sun (about 99.866%); it holds by its gravity the planets and other bodies belonging to Solar system and revolving around the sun. The table shows the main characteristics of the planets of the solar system.
Table.
Comparative table of some parameters of the planets
* The parameters in the table are indicated in relation to the analogous data of the Earth.
Between the orbits of Mars and Jupiter is the main belt of asteroids - minor planets. There are many asteroids; they collide, disintegrate, change the orbits of each other, so that some of the fragments, as they move, cross the Earth's orbit.
The passage of debris (meteoric bodies) through the earth's atmosphere looks like "shooting stars" from the surface of the earth. On rare occasions when larger fragments pass, a fireball can be seen flying across the sky. This phenomenon is called a fireball.
Moving in the atmosphere, a solid body heats up due to deceleration, and an extensive luminous shell, consisting of hot gases, forms around it. From strong air resistance, a meteoric body often splits, and its fragments - meteorites with a roar fall to the Earth.
16. Which of the parameters indicated in the table increases with the distance of the planet fromThe sun?
