Must two quantities have the same dimensions if you are multiplying them?
No
Must two quantities have the same dimensions if you are subtracting them?
Yes.
Must two quantities have the same dimensions when subtracting them?
Yes they must be in the same units of measurements.
Is it true that two quantities having the same dimensions must be measured in the same units?
No, it is not true.
Is it possible for two quantities to have the same units but different dimensions?
No. Measurement units are defined by and conversely. So the same units necessarily means same dimensions.
For two vector quantities to be equal they must have the same direction and the same?
Same direction and equal magnitudes.
What is the dimension of 27 83?
The answer will depend on (a) whet the dimensions of the two quantities are, and (b) what the missing operator between the two quantities is.
Must two quantities have the same dimensions if you are adding them in physics?
Yes, always. One molecule plus one atom is not 2 of anything. One unit north plus one unit east is not 2 units northeast. ■
What is it called when you multiply or divide two quantities by the same number?
Scaling is when you multiply or divide two quantities by the same number.
Is it possible for two quantities to have the same dimensions but different units?
Certainly. [Speed] may have units of feet per second, kilometers per hour, or furlongs per fortnight.
Two quantities that have the same units have the same dimensionality?
True-
What does the golden ratio means?
In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities.
