I. Complete the sentences from the text with the words in the box and get one point for each correct answer.

Energy is involved when a bird flies, rain falls from the sky, electricity flows in a wire. When work is done to an object, it acquires 1______________. The energy it acquires is known as 2 _________ energy. The energy of 3 ___________ is called kinetic energy. The faster an object moves, the more kinetic energy it has. The greater the mass of a moving object, the more kinetic energy it has. 4_____________ energy depends on both mass and velocity. 5______________ energy is stored energy. Stored chemically in fuel, the nucleus of atom, and in foods or stored because of the work done on it: stretching a rubber band or winding a watch.

The number of sound waves per second is called the frequency of the sound

Solving a system of linear equations

There are three cases when looking for solutions to a system of linear equations: there is no solution, 16______________, there are many solutions; the exact number depends on the properties of the field. In many cases there will be an infinite number of solutions. There are two categories of methods for solving a system of linear equations. Iterative methods use many steps to get a solution, direct methods use only one step: an example for 17___________________; this variable can be eliminated and replaced by an expression that only uses other variables, or a number. Doing this for all variables of the equation 18________________. Another method is to transform two equations so that one of the sides of the equations 19______________; it is then possible to write another equation 20_______________.

а) which replaces the two equations and reduces the number of equations by one.

b) there is exactly one solution

c) a direct method is to solve the system for one variable

d) is the same in both cases

e) will lead to a solution of the system if it exists.
