Question

Q6. Define the following terms. (5 marks)
i) Artificial satellite
ii) Light year.
3)Red data book
iv) Ore
v) Magnetic force​

Answer 1

Answer:

1. An artificial satellite is an object that people have made and launched into orbit using rockets. There are currently over a thousand active satellites orbiting the Earth. The size, altitude and design of a satellite depend on its purpose.
2. a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km (nearly 6 million million miles).
3. Red Data Book of the Russian Federation (RDBRF), also known as Red Book or Russian Red Data Book is a state document established for documenting rare and endangered species of animals, plants and fungi, as well as some local subspecies (such as the Ladoga seal) that exist within the territory of the Russian Federation and its continental shelf and marine economic zone. The book has been adopted by Russia to enact a common agreement on rare and endangered species protection.
4. a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably
5. Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

Explanation:

Answer 2

artificial satellite is a object intentioned to be in the earths orbit for many reasons

light year is a measure a of lenght which is the distance light covers in a year

red data book is a list of all endangered species of animals and palnts in a country

ore is a mixture of different types of minerals with impurities found naturally

magnetic force is a powerful force which can attract and repulse according to the composition of the object
