Cosmic Microwave Background Radiation {Ans: Created after big bang, still detectable today.}How to resolve forces (force diagram steps) {Ans: 1. Decide on a scale of N per cm. 2. Draw the 2 given forces, giving respect to their length (more cm if more N) and the angle that you are given 3. Draw a line connecting the end of the 2 other lines to form a triangle 4. Measure the length of this line, then convert it to N by using the scale}Characteristics of a permanent magnet {Ans: •A material that produces its own magnetic field. •Made from ferrous materials or alloys with them (e.g. iron, cobalt, nickel and steel). •Substances that are permanently magnetised and often their alloys are called "magnetically hard". •Alloys with less concentration of the ferrous material are often weaker, temporarily magnetised and therefore magnetically soft.}Process of reaching terminal velocity {Ans: 1.Accelerates due to weight. 2.Air resistance increases with velocity, weight does not. 3.Air resistance becomes equal to weight, the forces become equal}The further a satellite is from the Earth... {Ans: -The less speed needed to orbit (gravity is weaker) -The longer the time for one orbit (moving a further distance
