shows two strips of staples. width of strip strip of 40 staples NOT to scale The width of one strip is 56 mm. There are 40 staples in the strip. Calculate the average width of one staple. average width of one staple = mm A student wants to find the volume of one strip of 40 staples. The student has a measuring cylinder and a beaker of water as shown in . strip of staples measuring cylinder water Describe how the student can determine the volume of one strip of staples by using the equipment shown in . The staples are made from a block of metal. The mass of the block is 296 g. The volume of the block is 33.2 cm3. Calculate the density of the metal. Include the unit. density of the metal = unit

A student determines the volume of a piece of metal. The student pours 30 cm3 of water into a measuring cylinder. The piece of metal is submerged in the water and the new volume reading on the measuring cylinder is 42 cm3. Calculate the volume of the piece of metal. volume = cm3 The mass of another piece of metal is 320 g. The volume of the piece of metal is 40 cm3. Calculate the density of the metal. Give the correct unit. density = unit The student drops the piece of metal into a tank of water. Two vertical forces act on the piece of metal as it falls through the water in the tank. On , each arrow represents a vertical force. piece of metal Complete the diagram in by labelling the two forces. The upward force is the same size as the downward force. Describe the motion of the piece of metal as it falls through the water.

A measuring cylinder contains 100 cm3 of water. 20 cm3 of the water is poured into a beaker. On , mark the level of the water left in the cylinder. A rule, calibrated in cm, is placed alongside the measuring cylinder, as shown in . What is the length of the measuring cylinder, from zero up to the 100 cm3 mark? The volume of a cylinder is found using the equation volume = cross-sectional area × length. Calculate the cross-sectional area of the measuring cylinder. cross-sectional area = cm3 cm3 Use
