Carla ejerce una fuerza de módulo igual a 250 N sobre un refrigerador, logrando
desplazarlo 12 m en una superficie horizontal. Si se desprecia el roce, ¿cuál es el trabajo
realizado por la fuerza, si esta fue ejercida en la misma dirección y sentido que el
movimiento del refrigerador?

Ответ:
Note the position of the vernier scale zero on the main scale. The main scale reading is the division just before where the zero mark of the vernier scale is aligned. So is the zero mark aligns just after the fifth division between 3 and 4 the main scale reading is then 3.5.
The next step is to take the vernier scale reading. To do this find the mark on the vernier scale which lines up perfectly with a mark on the main scale. The vernier reading can then be found by multiplying the least value of the vernier scale with the number of divisions till that mark. For example if the least value is 0.01 mm and the 7thmark of the vernier scale is lined up perfectly then the vernier scale reading is 7 x 0.01 = 0.07.
The final step is to add the main scale and vernier readings to get the final measurement. For example 3.5 + 0.07 = 3.57 mm.
