Question: "What are dielectrics used in?" Context: "Most types of capacitor include a dielectric spacer, which increases their capacitance. These dielectrics are most often insulators. However, low capacitance devices are available with a vacuum between their plates, which allows extremely high voltage operation and low losses. Variable capacitors with their plates open to the atmosphere were commonly used in radio tuning circuits. Later designs use polymer foil dielectric between the moving and stationary plates, with no significant air space between them." Answer:
Ans: capacitor

Question: "Which of the following is not a potential source of tensions for children: school, agriculture or home?" Context: "While full-time work hinders schooling, empirical evidence is varied on the relationship between part-time work and school. Sometimes even part-time work may hinder school attendance or performance. On the other hand, many poor children work for resources to attend school. Children who are not doing well at school sometimes seek more satisfactory experience in work. Good relations with a supervisor at work can provide relief from tensions that children feel at school and home. In the modern world, school education has become so central to society that schoolwork has become the dominant work for most children, often replacing participation in productive work. If school curricula or quality do not provide children with appropriate skills for available jobs or if children do nor have the aptitude for schoolwork, school may impede the learning of skills, such as agriculture, which will become necessary for future livelihood." Answer:
Ans: agriculture
