Sara and Saba are identical twins who are the same in every way, including their weights. One day, Sara and Saba decided to go for a walk in the snow. They got dressed, and then Saba put on her favorite red heels. Meanwhile, Sara, who had always been more practical, put on her snowshoes.
As soon as they stepped out onto the snow, Saba's heels sank right through while Sara had no trouble walking on top of the snow in her snowshoes!
Q1: Why do you think this happened? If Sara and Saba weigh the same and are exactly of the same size, why did Saba fall through the snow while Sara did not?
Q2: Calculate pressure under Sara’s snowshoes.
Q3: How is pressure useful in everyday life? Give an example.
Q4: State the factors affecting pressure.
Q5: How do snowshoes help a person to walk easily on soft snow?
