What should you do if the pointer and zero mark are not aligned before measuring?

• Both B and C

• Adjust the riders to zero

• Ignore it and proceed

• Turn the adjustment knob

What is the first step in using the triple beam balance to measure an object?

• Ensure the pointer and zero mark are aligned

• Move the 100 gram rider

• Turn the adjustment knob

• Place the object on the measurement tray

How do you determine the mass using the 100 gram rider?

• Move it 0.1 grams at a time

• Move it 100 grams at a time

• Move it 1 gram at a time

• Move it 10 grams at a time

What should you do if the pointer drops when moving the 10 gram rider?

• Move it back one notch

• Reset the balance

• Move it forward one notch

• Ignore it

How many times should you measure the mass of an object to ensure accuracy?

• Three times

• Twice

• Once

• Four times

How do you calculate the average mass of an object?

• Add the measurements and divide by two

• Add the measurements and divide by the number of measurements

• Multiply the measurements together

• Subtract the smallest measurement from the largest
