Exploring Tech Concepts

What is a magnet and how does it work?

• A magnet is a device that generates electricity through friction.

• A magnet is an object that creates heat when in motion.

• A magnet is a type of battery that stores energy.

• A magnet is an object that produces a magnetic field, attracting or repelling certain materials.

Name two types of magnets and their uses.

• Neodymium magnets and their use in jewelry

• Ceramic magnets and their use in batteries

• Permanent magnets and electromagnets

• Bar magnets and their use in compasses

What is an electric circuit?

• A type of electrical appliance that uses power.

• A series of batteries connected in parallel.

• An electric circuit is a closed path through which electric current flows.

• A device that stores electrical energy.

What are the main components of a simple electric circuit?

• Generator, diode, transformer

• Power source, switch, resistor

• Battery, wire, capacitor

• Power source, conductive path, load

How does electricity flow in a circuit?

• Electricity moves in a straight line without any conductors.

• Electricity flows in an open circuit without any resistance.

• Electricity only flows when there is no voltage present.

• Electricity flows in a closed circuit driven by voltage, allowing electrons to move through conductors.

What is the difference between a series and a parallel circuit?

• A series circuit has multiple paths for current, while a parallel circuit has a single path.

• A series circuit has a single path for current, while a parallel circuit has multiple paths.

• In a series circuit, components are connected in a grid, while in a parallel circuit, they are in a line.

• A series circuit allows for independent operation of components, while a parallel circuit requires all components to function together.

What are the different types of refugees?

• Political refugees, Economic refugees, Environmental refugees, Religious refugees, Asylum seekers

• Cultural refugees

• Historical refugees

• Social refugees

What challenges do refugees face when relocating?

• Refugees receive unlimited financial support from governments.

• Refugees have no issues finding housing and healthcare.

• Refugees face challenges such as language barriers, cultural differences, legal hurdles, limited access to jobs and education, and psychological trauma.

• Refugees easily adapt to new cultures and languages.

What types of food are commonly provided to refugees?

• Exotic fruits like mangoes and pineapples

• Fast food items like burgers and fries

• Staple foods like rice, beans, lentils, canned vegetables, and pasta.

• Luxury items like caviar and truffles

How can scrap metal be recycled?

• Scrap metal is used as fuel for burning.

• Scrap metal is buried underground to decompose.

• Scrap metal is recycled by collecting, sorting, cleaning, processing, and melting it into new products.

• Scrap metal is thrown away in landfills.
