Neco 2024 Physics Question 1

An irregularly shaped metal specimen is to be investigated for its density using a spring balance and a graduated cylinder. The procedure is: 1. Zero the spring balance and hang the specimen. Record the mass reading. 2. Fill a clean graduated cylinder with water to an initial volume and record the reading. 3. Gently lower the specimen into the water (without touching the sides) and record the new water level. 4. Remove the specimen, dry it and return the balance to zero. The following data are obtained: - Mass reading on the spring balance: 45.6 g - Initial water volume: 30.0 mL - Final water volume after immersion: 38.5 mL - Temperature of the water: 25 °C (density of water at this temperature = 0.997 g·cm⁻³) Using the above information, answer the following:
