Remove the first 10 p coin and place the second coin at the centre of the weighing container. Record the total weight (W3). Determine the weight of the second 10 p coin by difference (W4 = W3-W0). Using your calculator, find the sum (W5 of the two 10 p coins (W5W₂+W4)). 3. Record your total weight (W5) in your copy of Table 1.2. 4. Now place both 10 p coins at the centre of the weighing container and record the total weight (W6). Determine the total weight of the two coins (W7) by difference (W7 = W6-WO). 5. Record your combined weight (W7) in your copy of Table 1.2. 6. Repeat steps 1 - 5 for the rest of the coins. 7. In the last row, you are expected to weigh the 20 p and 50 p coins together. 8. Draw a graph of Weights-W5 on the vertical axis and Weights-W7 on the horizontal axis. ame of balance)
