What is the role of calibration in the use of forensic balances?

• To ensure accuracy and reliability of measurements

• To increase the speed of measurement

• To change the unit of measurement

• To enhance the visual display

Which of the following materials is commonly used for the construction of forensic balance pans?

• Stainless steel

• Plastic

• Glass

In a forensic investigation, why might a scientist choose a balance with a draft shield?

• To prevent air currents from affecting measurements

• To protect the sample from contamination

• To enhance the aesthetic appearance

• To increase the weight capacity

What is the significance of the term 'tare' in the context of forensic balances?

• It refers to setting the balance to zero with a container on it

• It is a measure of the balance's sensitivity

• It indicates the maximum weight capacity

• It describes the balance's calibration status
