Oh, what a lovely question! To make 9p using 5p, 2p, and 1p coins, we can start by using one 5p coin and two 2p coins, which equals 9p. Alternatively, we can use four 2p coins and one 1p coin, also totaling 9p. It's all about finding different combinations like these to reach the desired total. Just like painting, there are many beautiful ways to create the perfect picture!
There are 31 ways:1p × 211p × 19 + 2p × 11p × 17 + 2p × 21p × 16 + 5p × 11p × 15 + 2p × 31p × 14 + 2p × 1 + 5p × 11p × 13 + 2p × 41p × 12 + 2p × 2 + 5p × 11p × 11 + 2p × 51p × 11 + 5p × 21p × 10 + 2p × 3 + 5p × 11p × 9 + 2p × 61p × 9 + 2p × 1 + 5p × 21p × 8 + 2p × 4 + 5p1p × 7 + 2p × 71p × 7 + 2p × 2 + 5p × 21p × 6 + 2p × 5 + 5p1p × 6 + 5p × 31p × 5 + 2p × 81p × 5 + 2p × 3 + 5p × 21p × 4 + 2p × 6 + 5p × 11p × 4 + 2p × 1 + 5p × 31p × 3 + 2p × 91p × 3 + 2p × 4 + 5p × 21p × 2 + 2p × 7 + 5p × 11p × 2 + 2p × 2 + 5p × 31p × 1 + 2p × 101p × 1 + 2p × 5 + 5p × 21p × 1 + 5p × 42p × 8 + 5p × 12p × 3 + 5p × 3
because old 2p coins are made out of bronze. Bronze is made out of tin and copper, these metals aren't magnetic. However, new 2p coins just look like they are made out of copper, however they only have a coating of copper on them, but the inside is steel, this is called copper plated steel. They are magnetic because steel is magnetic and makes up the majority of the coin.
No, a 2p coin cannot scratch apatite. Apatite is composed of calcium phosphate minerals which are harder than the metal used in a 2p coin.
A 2p coin in the UK weighs approximately 7.12 grams.

No, a 2p coin is unlikely to scratch apatite and orthoclase as these minerals have a higher hardness on the Mohs scale compared to the coin. Apatite has a hardness of 5 on the Mohs scale, while orthoclase has a hardness of 6-6.5, higher than the 2p coin.
That makes it easier to distinguish them.
