3.1 The first artificial satellite was launched by A) the Soviet Union B) USA C) UK D) Kazakhstan E) China

3.2 A quantity that can be completely described by a magnitude is A) Scalar B) Vector C) Resultant D) Scalar Product E) Vector Product

1. List of Symbols in physics include express the concepts in physics from school and university courses. Also included are general and mathematical concepts and operations in order to enable complete reading of the physical formulas. For the representation of physical quantities and concepts in physics use Latin and Greek alphabets, as well as several special characters and diacritics. Because the number of physical quantities greater than the number of letters in the Latin and Greek alphabets, the same letters are used to denote different quantities.

2. Mechanical motion, the reference frame moving, speed, acceleration. Mass, Strength, Strength of elasticity, Young's modulus, friction force, weight. Inertial reference systems, Impulse body, system of bodies, mechanical, potential, kinetic energy, power, Statics, molecular physics, thermal motion. Field, dielectrics, Dipole

3. Transverse wave - a wave propagating in a direction perpendicular to the plane in which the medium particle oscillations (in the case of elastic waves), or in which the vectors of the electric and magnetic fields (for electromagnetic waves). For transverse waves include, for example, waves in elastic strings or membranes.

Longitudinal waves called wave in which vibrations occur along the direction of propagation. An example of such waves can be acoustic (elastic) waves, in rare cases, there are examples of longitudinal electromagnetic waves (in strongly dispersive media).

4. Nuclear reaction - a process of interaction between the atomic nucleus with another nucleus or elementary particle, accompanied by changes in the composition and structure of the nucleus and the release of large amounts of energy. First nuclear reaction observed by Rutherford in 1919, α-particles bombarding atomic nuclei of nitrogen. On the mechanism of interaction of nuclear reactions are divided into two types: reaction to form a compound nucleus, is a two-step process that takes place is not very high kinetic energy of the colliding particles (up to about 10 MeV). -direct nuclear reactions taking place in a nuclear time required for the particle crossed the kernel. Mainly, such a mechanism is shown at higher energies bombarding particles.
