Yes, that is correct. Altitude above sea level, for example, is negative or positive - if you are below sea level, a negative number will be used.
Ozone has a positive role in the stratosphere. It also have a negative role in ground level.
Depends upon where you are at the moment. Most of the nation is above sea level (positive numbers) Death Valley (CA) is 250 feet below sea level (negative number)
If an altitude above sea level is positive, then an altitude below sea level is negative.If having money is positive, having a debt is negative.If gaining money is positive, losing money is negative (a negative gain).If an increase in speed is a positive acceleration, a decrease in speed is a negative acceleration.Any other similar case, where you define one thing as positive, and its opposite as negative.
could be negative or positive"negative logic" just means, that the level used by "positive logic" within that logic family for False, is instead used for "True" and vice versa.
in a cumulonimbus cloud (a thunderstorm cloud) there are negative and positive charges. the ground is positive, the lower level of the cloud is negative and the upper level of the cloud is positive. When lightning is about to take place there is one path where negative and positive charges crossing, thus creating an electrical charge, in other works lightning.
For example, an altitude above sea-level can be expressed as a positive number; below sea-level is negative.Or: If you have money, you have a positive amount of money; if you owe money, that goes against you, you have "less than nothing", so it can be expressed as a negative amount.In technology and science - would you classify that as "real-world"? - negative numbers are used all the time. For example, if you decide that moving in a certain direction (e.g., "up") is positive, a movement in the opposite direction is negative.
The Earth's core
Positive (Rises) , neutral (Level) and negative (Sinks) buoyancy .
Altitude describes an object's position relative to sea level. An object in a position higher than sea level would have a positive altitude, sea level would have an altitude of zero, and any object below sea level would have a negative altitude.
Rhetoric can have both a negative and positive affect on the audience depending on the subject being discussed and the education level of the audience. For example I would never go into to a long rhetorical dissertation about creationism to an audience of teens and children or people who have no clue about creationism. It can be positive if it is used to stretch the think and logical reasoning of the audience, such as in a classroom or lecture room. The idea of rhetoric is not to confuse but to introduce a point and come to a conclusion. If you confuse your audience you have cause a negative effect of confusion of the listener.
