Self intrest and exchanging things for mutual benefit
Answer:
d. All of the above
Explanation:
A scale can be defined as an ordered numerical or alphabetical sequence that is typically used for taking measurements such as size, weight, height, length, etc. Also, a scale is used in the field of science to assign magnitude to physical activities and natural phenomenons such as an earthquake using the Richter scale.
In Science, there are four (4) main scales of measurement and these includes;
1. Interval scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.
2. Ratio scale: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.
3. Ordinal scale: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.
4. Nominal scale: it is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.
<em>Hence, scales can represent;</em>
<em>a. A range of information. </em>
<em>b. A range of resources. </em>
<em>c. Proportional measurement. </em>
Answer:
The sailboat moves southward at a force of 1000 Newton
Explanation:
The sailboat is moving south at 2500 newtons. The opposite force is only 1500 newtons, which is less than 2500 units. The greater force cancels out the lesser force. In order for the boat to be stopped or pushed back, the water and air resistance would of had to of been greater than or equal to 2500 Newtons. Because of this opposite force, the boat continues to move but with a lesser amount of force. You can use subtraction to find the remaining force the boat has.
2500 Newtons - 1500 Newtons = 1000 Newtons
