Here is a question about this article: Vinyl pressings were made with stampers from master cuts that were electroplated in vacuo by means of gold sputtering. Audio response was claimed out to 8,000 Hz, later 13,000 Hz, using light weight pickups employing jeweled styli. Amplifiers and cutters both using negative feedback were employed thereby improving the range of frequencies cut and lowering distortion levels. Radio transcription producers such as World Broadcasting System and Associated Music Publishers (AMP) were the dominant licensees of the Western Electric wide range system and towards the end of the 1930s were responsible for two-thirds of the total radio transcription business. These recordings use a bass turnover of 300 Hz and a 10,000 Hz rolloff of −8.5 dB.
What is the answer to this question: What were used to make vinyl pressings?

So... master cuts


Here is a question about this article: Common energy forms include the kinetic energy of a moving object, the potential energy stored by an object's position in a force field (gravitational, electric or magnetic), the elastic energy stored by stretching solid objects, the chemical energy released when a fuel burns, the radiant energy carried by light, and the thermal energy due to an object's temperature. All of the many forms of energy are convertible to other kinds of energy. In Newtonian physics, there is a universal law of conservation of energy which says that energy can be neither created nor be destroyed; however, it can change from one form to another.
What is the answer to this question: What law states, in part, that energy can change from one form to another?

So... Newtonian physics


Here is a question about this article: In 1936, Wever was killed in an air crash. The failure to implement his vision for the new Luftwaffe was largely attributable to his immediate successors. Ex-Army personnel Albert Kesselring and Hans-Jürgen Stumpff are usually blamed for the turning away from strategic planning and focusing on close air support. However, it would seem the two most prominent enthusiasts for the focus on ground-support operations (direct or indirect) were actually Hugo Sperrle and Hans Jeschonnek. These men were long-time professional airmen involved in German air services since early in their careers. The Luftwaffe was not pressured into ground support operations because of pressure from the army, or because it was led by ex-army personnel. It was instead a mission that suited the Luftwaffe's existing approach to warfare; a culture of joint inter-service operations, rather than independent strategic air campaigns.
What is the answer to this question: What year did Wever die?

So...
1936
