Question

what masses are shown on each of the following balances? triple beam balance answer: 602.8 answer: 523.6g answer:

Explanation:

Step1: Identify values on each beam

The top beam has increments of 10 g, middle beam of 100 g and bottom beam of 1 g.

Step2: For first balance

Top beam value is 20 g, middle beam value is 600 g and bottom beam value is 2.8 g. Total mass is $20 + 600+2.8=622.8$ g.

Step3: For second balance

Top beam value is 10 g, middle beam value is 400 g and bottom beam value is 3.6 g. Total mass is $10 + 400+3.6 = 413.6$ g.

Step4: For third balance

Top beam value is 0 g, middle beam value is 200 g and bottom beam value is 0.8 g. Total mass is $0+200 + 0.8=200.8$ g.

Answer:

622.8 g
413.6 g
200.8 g
