Answer 1

Answer:

• time is measured in sec and minutes
• distance is measured in m and km
• length is measured in cm and metre
• mass and s measured in gm and kg

Answer 2

Answer:

The following items are measured:

Time

• Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.
• It is a quantity that is a part of several measures that are used to compare the length of events or the gaps between them, to compare how long they last, to order events, and to measure how quickly things change in the actual world or in our conscious experience.
• Along with the three spatial dimensions, time is frequently referred to as a fourth dimension.
• It is usually measured in Seconds, Minutes, and hours.

Distance:

• Distance is a measure of how far away two objects or locations are using numbers.
• The distance can refer to a physical length in physics or to an estimate based on other factors in common use.
• Sometimes, the distance between two points is expressed as The terms "distance from A to B" and "distance from B to A" are frequently used interchangeably.
• A distance function or metric is a technique to describe what it means for components of space to be "near to" or "far away" from each other in mathematics. It is an extension of the idea of physical distance.
• Distance is a non-numerical measurement used in psychology and other social sciences.
• It is usually measured in Centimeters, Meters, and Kilometers.

Length:

• Distance is measured in length.
• The length has the dimension of distance in the International System of Quantities.
• The majority of measuring systems choose a base unit for length from which all other units are derived.
• The meter serves as the foundational unit of length in the International System of Units (SI) system.

• It is usually measured in Centimeters, Meters, and Kilometers.

Mass​:

• Mass is a physical body's total amount of matter.
• It also serves as a gauge for the body's inertia, or resistance to acceleration (change in velocity) in the presence of a net force.
• The intensity of an object's gravitational pull on other bodies is also influenced by its mass.
• It is usually measured in Grams, Kilograms, and Tonnes.
