Please answer the following question: Information:  - The Eurovision Song Contest, sometimes popularly called Eurovision but not to be confused with the Eurovision network that broadcasts it, is the longest-running annual international TV song competition, held, primarily, among the member countries of the European Broadcasting Union (EBU) since 1956. The competition was based upon the existing Sanremo Music Festival held in Italy since 1951.  - Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 GHz to as low as 3 kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency. At 300 GHz, the corresponding wavelength is , and at 3 kHz is . Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are generated by lightning, or by astronomical objects.   - Information is that which informs. In other words, it is the answer to a question of some kind. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.  - The amplitude of a periodic variable is a measure of its change over a single period (such as time or spatial period). There are various definitions of amplitude (see below), which are all functions of the magnitude of the difference between the variable's extreme values. In older texts the phase is sometimes called the amplitude.  - Alternating current (AC), is an electric current which periodically reverses polarity, whereas direct current (DC, also dc) flows only in one direction with a single polarity either positive or negative. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electric energy that consumers typically use when they plug kitchen appliances, televisions and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations "AC" and "DC" are often used to mean simply "alternating" and "direct", as when they modify "current" or "voltage".  - Teleradio - Moldova is the state - owned national radio - TV broadcaster . It owns the TV channels Moldova 1 and TVMI and the radio channels Radio Moldova and Radio Moldova Internaional . TRM was admitted as a full active member of the European Broadcasting Union on 1 January 1993 , under its former name Radioteleviziunea Nationala din Moldova ( RTNM ) .  - In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions. A metal wire is a common electrical conductor. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases.   - Moldova (or sometimes ), or Moldavia, officially the Republic of Moldova, is a landlocked country in Eastern Europe, bordered by Romania to the west and Ukraine to the north, east, and south. The capital city is Chiinu.  - Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.  - Radio Moldova (RM) is the first publicly funded radio broadcaster in Moldova.  - The European Broadcasting Union (EBU) is an alliance of public service media entities, established on 12 February 1950. As of 2015, the organisation comprises 73 active members in 56 countries, and 34 associate members from a further 20 countries. Most EU states are part of this organisation and therefore EBU has been subject to supranational legislation and regulation. It also hosted debates between candidates for the European Commission presidency for the 2014 parliamentary elections but is unrelated to the institution itself. It is best known for producing the Eurovision Song Contest. EBU is a member of the International Music Council.  - The European Commission (EC) is an institution of the European Union, responsible for proposing legislation, implementing decisions, upholding the EU treaties and managing the day-to-day business of the EU. Commissioners swear an oath at the European Court of Justice in Luxembourg, pledging to respect the treaties and to be completely independent in carrying out their duties during their mandate.  - Technology ("science of craft", from Greek , "techne", "art, skill, cunning of hand"; and , "-logia") is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines which can be operated without detailed knowledge of their workings.  - Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its periodthe time interval between beatsis half a second (that is, 60 seconds divided by 120 beats). Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio (sound) signals, radio waves, and light.  - Moldova 1 is the national Moldovan television channel, operated by the national public broadcaster, TeleRadio-Moldova.  - The International Music Council (IMC) was created in 1949 as UNESCO's advisory body on matters of music. It is based at UNESCO's headquarters in Paris, France, where it functions as an independent international non-governmental organization. Its primary aim is to facilitate the development and promotion of international music-making.  - In physics, energy is the property that must be transferred to an object in order to perform work on  or to heat  the object, and can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the mechanical work of moving it a distance of 1 metre against a force of 1 newton.    Given the information, choose the subject and object entities that have the relation of 'instance of'.
