Question

________ is a scalar quantity.

Answer 1

Answer:

Scalar quantities are defined by a magnitude with no applicable direction. In contrast, vector quantities must have both magnitude and direction of action. Some common scalar quantities are distance, speed, mass, and time. Some common vector quantities are force, velocity, displacement, and acceleration.

Answer 2

A substance with a magnitude but no applicable direction is a scalar quantity.

Explanation:

• Scalar quantities are physical quantities with only one magnitude. A unitless measure of an object's brightness in a defined passband, usually in the visible or infrared spectrum, but sometimes over all wavelengths, is called magnitude.
• Distance, speed, mass, and time are all examples of scalar variables. Force, velocity, displacement, and acceleration are some frequent vector quantities.
• The term "magnitude" is used to describe the size of something or the distance between two points. We can connect magnitude to the size and speed of the moving object.
• The length, breadth, and width of an earthquake are used to determine its magnitude. The physical size of the earthquake is used to calculate it.
