Question

triple beam balance practice determine the mass by reading the riders on the triple beam balance. be sure to include units with your answer.

Explanation:

Step1: Read large - mass beam

For each part, read the value on the 100 - g beam.

Step2: Read medium - mass beam

Read the value on the 10 - g beam.

Step3: Read small - mass beam

Read the value on the 1 - g beam.

Step4: Sum up values

Add the values from the three beams to get the total mass.

For A:

1. The 100 - g beam reads 100 g, the 10 - g beam reads 20 g, and the 1 - g beam reads 0.6 g.
2. Total mass $m_A=100 + 20+0.6=120.6$ g

For B:

1. The 100 - g beam reads 100 g, the 10 - g beam reads 80 g, and the 1 - g beam reads 7.5 g.
2. Total mass $m_B=100 + 80+7.5=187.5$ g

For C:

1. The 100 - g beam reads 300 g, the 10 - g beam reads 60 g, and the 1 - g beam reads 9.7 g.
2. Total mass $m_C=300 + 60+9.7=369.7$ g

For D:

1. The 100 - g beam reads 400 g, the 10 - g beam reads 40 g, and the 1 - g beam reads 3.4 g.
2. Total mass $m_D=400 + 40+3.4=443.4$ g

Answer:

A. 120.6 g
B. 187.5 g
C. 369.7 g
D. 443.4 g
