No, the measured value from one point to another is not always positive. It can be negative depending on the context and the reference point used for measurement. For example, in coordinate systems, a negative value can indicate a position in the opposite direction from the reference point. Thus, the sign of the measured value conveys important information about direction and magnitude.
The measured value is always positive from one point to another when it represents a distance, as distance cannot be negative. This is because distance is typically defined as the scalar quantity that expresses how much space is between two points, irrespective of direction. In contrast, other measurements like displacement can be positive or negative depending on the reference point and direction.
DISTANCE!!!!
Yes, it is always positive. 0 K is the lowest temperature there can be.
It is because many things are measured with reference to a fixed point: it space or time. This point is called a reference point or origin.
Quantities such as speed, temperature, and position must always be measured or described relative to a reference point or standard in order to have meaning. For example, speed is measured relative to a specific point in time, temperature is measured relative to a chosen scale, and position is described relative to a coordinate system.
True. Motion is always measured in relationship to a point of reference. This point of reference can be stationary or moving itself, but it is essential for determining the position, speed, and direction of an object in motion.
An object in motion is moving in relation to a reference point. This reference point can be another object that is stationary or moving at a different speed or direction. The motion of an object is always observed or measured in relation to a reference point.
for the SI units of measurements, length is measured in meters. for anything else, length is measured in inches, feet, yards, etc.
The difference in electrical charge from one point to another measured in millivolts is called voltage. Voltage is a measure of the electrical potential difference between two points in a circuit and is responsible for the flow of electric current.
Positive polarity at the tip indicates that the tip of the electrode has a positive charge compared to the reference electrode. This is commonly used in applications such as electrophysiology, where a positive signal is measured relative to a ground or reference point to detect neuronal activity or other biological signals.
No, the height of a wave is measured from the top of one crest to the bottom of the same crest.
then our work is positive
