Explain three reasons why slavery is not suitable for many crops, define an electromagnet, and list three ways to increase its strength.

Step 1: Answer Question 1.

(a) Three reasons why slavery is not suitable for cultivating many crops are:

• Low productivity due to lack of motivation and forced labor.
• High supervision costs required to manage and control enslaved workers.
• Risk of resistance or sabotage by enslaved individuals, leading to crop damage or loss.

(b) An electromagnet is a temporary magnet created when an electric current flows through a coil of wire, typically wrapped around a soft iron core.

(c) Three ways to increase the strength of an electromagnet are:

• Increase the number of turns in the coil of wire.
• Increase the current flowing through the coil.
• *Insert a soft iron
