The correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is; 1
<h3>What is the Correct Scale Calibration?</h3>
We are told that a certain scale is not calibrated correctly,
Mass displayed = 0.75 kg (less than its actual mass).
The scale of display = 1
Thus, the correlation between actual mass and displayed mass is 1 due to the fact that correlation is independent of change of origin and scale and correlation between any value and value minus 0.75 will be one.
Thus, the correlation between the actual masses of a set of objects and the respective masses of the same set of objects displayed by the scale is 1.

The magnitude of an object's charge can either increase or decrease the attraction/ repulsion between another object. The larger the difference of the two object's charges, the stronger opposite charges attract, and the stronger like charges repel.

In perfectly competitive markets, firms in the market in the long-run, will earn zero economic profits.
<h3>What economic profits are earned in a perfectly competitive market?</h3>
In the short-run, there is a chance to earn a positive economic profit in a perfectly competitive market but this would then attract other companies into the market to make profits as well.
This then leads to the profits disappearing thanks to increased supply and lower prices. Companies would then leave and enter to either take advantage of profits or stop losses thereby keeping economic profits at zero in the long run.
