The student is asked to calculate the density of a stone, identify the equipment used to measure mass and volume, and determine which food types attract the most birds based on a graph.

Here are the solutions to your questions. QUESTION 8 i) Complete the equation in the box below using the words given. The formula for density is mass divided by volume. Density = MassVolume ii) What piece of equipment could the student have used to measure the mass of the stone? A digital balance or triple beam balance is used to measure mass. iii) Describe how you can use the displacement method to find the volume of the stone. Step 1: Partially fill a measuring cylinder with water and record the initial volume (V_1). Step 2: Carefully place the stone into the measuring cylinder, ensuring it is fully submerged. Step 3: Record the new, higher volume of water (V_2). Step 4: Calculate the volume of the stone by subtracting the initial volume from the final volume: V_stone = V_2 - V_1. QUESTION 9 According to the graph, the food types that attracted the most birds are Safflower (20 birds) and Sunflower (15 birds). Therefore, a combination of these two would likely bring the most birds to the feeder. The combination of food that would probably bring the most birds to the feeder is Safflower and Sunflower.
