Sagot :
Certainly! Let's fill in the table with the appropriate forces for each motion.
[tex]\[ \begin{tabular}{|l|l|} \hline \textbf{Column A} & \textbf{Column B} \\ \hline \begin{tabular}{l} Roller blades moving \\ forward \end{tabular} & Pushing force \\ \hline \begin{tabular}{l} Hairdresser drying \\ your mum's hair with \\ the blow dryer \end{tabular} & Blowing force \\ \hline \begin{tabular}{l} Stretching an elastic \\ band \end{tabular} & Tensile force \\ \hline Tying your shoelaces & Tension force \\ \hline \end{tabular} \][/tex]
Explanation of each entry:
1. Roller blades moving forward: The force involved here is a pushing force because you push against the ground to move forward.
2. Hairdresser drying your mum's hair with the blow dryer: The force involved here is a blowing force, as the blow dryer exerts a force by blowing air at a high velocity.
3. Stretching an elastic band: The force here is a tensile force, which refers to the force applied when you pull something apart, causing tension in the material.
4. Tying your shoelaces: The force involved here is tension force, which is the stress that results when you pull the laces taut to tie them.
