Question

what is the weight shown on the spring scale? remember, you should read the weight displayed at the top of the plunger. n 0 0.5 1.0 1.5 2.0 1.1 n 1.5 n 1.4 n 1.3 n

Explanation:

Step1: Identify scale intervals

The scale ranges from 0 - 2.0 N. There are 20 small - scale intervals between 0 and 2.0 N. So each small - scale interval represents $\frac{2.0 - 0}{20}=0.1$ N.

Step2: Locate the top of the plunger

The top of the plunger is 11 intervals above 0.

Step3: Calculate the weight

The weight is $11\times0.1 = 1.1$ N.

Answer:

1.1 N
