Sure, let's identify each of the metals (M), (N), (O), and (P) as described in the given table.
1. Bicycle handlebars: Iron (Metal to be coated: (M))
- Handlebars are typically made from iron or its alloys and are often coated with a layer of Nickel to prevent rust and to give a nice finish.
- Thus, the metal (M) used to coat bicycle handlebars is Nickel.
2. Machinery Parts: ...(N) (Metal to be coated: Chromium)
- Machinery parts are often made from Steel due to its strength and durability. These parts are sometimes coated with Chromium to increase hardness, resistance to corrosion, and to improve its appearance.
- Hence, the metal (N) which machinery parts are made of is Steel.
3. Ornaments: Copper or its alloys (Metal to be coated: (O))
- Ornaments are sometimes made of Copper or its alloys and are often coated with Gold to improve their appearance, prevent tarnishing, and to increase their value.
- Therefore, the metal (O) that ornaments are coated with is Gold.
4. Food Cans: ...(P) Iron (Metal to be coated: Tin)
- Food cans are usually made from Iron, which is coated with Tin to prevent rusting and to protect the food from the metal.
- Thus, the part (P) is Food Cans.
Putting it all together, we get:
- (M) is Nickel
- (N) is Steel
- (O) is Gold
- (P) is Food Cans
Here's the completed table for clarity:
