Which of the following measurements is the most accurate for a pellet with a mass of 3.25 grams? a. 3 grams b. 3.20 grams c. 3.27 grams d. 3.50 grams

3.27 grams

Explanation:

The value that is measured should have minimum error and minimum difference in weight with respect to the actual weight of the equipment.

The original weight of the pellet with a mass of 3.25 grams is measured and the most accurate weight around this number is 3.27.

The slight difference is due to error and this error can be calibrated.

Hence, the correct option is 3.27.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
