Question

The correct reading of the vernier caliper would be (5 points)

7.5mm
8.5mm
10.5mm
34.5mm

Answer 1

The correct reading of the vernier caliper is 7.5 mm.

A vernier caliper is used to measure the diameter of a circular object such as;

• inner and outer diameter of a test tube.

• depth of a beaker.

• length of some measuring cylinders.

The reading of a vernier caliper is obtained by adding the reading of the main scale and vernier scale.

The vernier scale reading is obtained from the smaller scale.

In the diagram given;

• the main scale reading = 7 mm.

• the vernier scale reading = 0.5 mm.

The reading of the vernier caliper = (7mm + 0.5 mm) = 7.5 mm.

Thus, the correct reading of the vernier caliper is 7.5 mm.

Answer 2

Answer:

8.5mm

Explanation:

if you count the lines (on the top part of the caliper) from 0-10 its in between 8 and 9 right? So its not going to be 9, its not at 9. so thats our first part, 8. Then you look at the bottom part of the caliper. looking at all the numbers, the only one lined up is 5. so this means you have a reading of 8.5mm on your vernier caliper. :)

P.S.- I nearly made the mistake of picking A, and when I looked closer I saw it was at 8.5 not 7.5. Im probably to late to help you but for others looking for the right answer im glad i could help you out!
