State and justify the techniques you would use to reduce the errors of the following. Each explanation should show a clear understanding of why the technique is relevant in the particular situation.
1. Measure the time it takes for a ping pong ball to drop from a height of 50 cm and bounce 3 times.
2. Measure the voltage across a resistor. Imagine you are provided with a connected series circuit of battery in holder, resistor, lamp, contact switch, 2 connecting wires, and a multimeter.
3. Measure the mass of a washer if you are provided with 5 washers and a digital balance.
4. Find the leg room under the bench (distance from the ground to the bottom of the metal strip under the bench top). You are provided with a metre ruler.
