3.1 What law (laws) describe the behavior of ideal gas? A) Charles’, Gay-Lussac’s, and Boyle’s B) Stefan-Boltzmann C) Kelvin D) Fahrenheit E) Celsius

3.2 When a body moves in uniform circular motion, the acceleration is called A) Centripetal acceleration B) Uniform circular motion C) Nonuniform circular motion D) Range of a projectile E) Constant acceleration

1. A vector quantity or a vector is any quantity that has direction. The force acting on a material point, is a vector quantity, the vector because it has direction. The velocity of a material point is also a vector.

A scalar value or a scalar is any quantity that has no direction. Body temperature is a scalar value, scalar, as this value is not associated directions. Body weight and its density is the same scalars.

2. the law of universal gravitation of Newton. Under this act between any pair of bodies in the Universe is the force of mutual attraction. Like all physical laws, he is clothed in the form of a mathematical equation. If M and m are the masses of two bodies and D is the distance between them, then the force F mutual gravitational attraction between them is equal to: F = GMm/D² where G is the gravitational constant, determined experimentally. In SI units its value is approximately 6,67 × 10-11.

3. Electromagnetic wave - the propagation of electromagnetic fields in space. Electromagnetic wave is a process of sequential, interrelated changes to the vectors of the electric and magnetic fields perpendicular to the line of wave propagation, wherein the change in electric field causes a changing magnetic field, which, in turn, cause changes in the electric field.

4. Free fall is uniformly accelerated motion under the action of gravity, when other forces acting on the body are absent or negligible. On the Earth's surface (sea level) the acceleration of gravity varies from 9.832 m/S2 at the poles to 9,78 m/S2 at the equator. Free fall of bodies is called the fall of bodies to the Earth in the absence of air resistance (in a vacuum). At the end of the XVI century, the famous Italian scientist Galileo empirically with the available time precision established that in the absence of air resistance, all bodies fall to the Ground uniformly accelerated, and that at a given point of the Earth the acceleration of all bodies fall the same. Before that for nearly two thousand years since Aristotle, in science, it was generally believed that heavy bodies fall to the Earth faster than light.
