## What are measures in quantitative research?

Measures exist to numerically represent degrees of attributes. Quantitative research is based on measurement and is conducted in a systematic, controlled manner. These measures enable researchers to perform statistical tests, analyze differences between groups, and determine the effectiveness of treatments.

## What is SI unit of inductance?

The henry (symbol: H) is the SI derived unit of electrical inductance.

## WHAT IS A in dimensional formula?

Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. These will specify the nature of the unit and not its magnitude.

## What is the dimension of magnetic flux?

Magnetic Flux

Characteristic | Notes | |
---|---|---|

Metric (SI) Dimensions | length2 × mass × time-2 × electric-current-1 | These are the dimensions of the “magnetic flux” quantity in SI units. There are other unit systems used in electromagnetics that may assign different dimensions. |

## What is a specific resistance?

Specific resistance is defined as the resistance offered per unit length and unit cross-sectional area when a known amount of voltage is applied.

## What are the 7 basic units of measurement?

The seven SI base units, which are comprised of:

- Length – meter (m)
- Time – second (s)
- Amount of substance – mole (mole)
- Electric current – ampere (A)

## What are the three basic units of measurement?

The three most common base units in the metric system are the meter, gram, and liter. The meter is a unit of length equal to 3.28 feet; the gram is a unit of mass equal to approximately 0.0022 pounds (about the mass of a paper clip); and the liter is a unit of volume equal to 1.05 quarts.

## What are the 2 types of measuring cups?

There are two main types of measuring cups—dry measuring cups and liquid measuring cups—and it matters which one you use. Dry measuring cups are designed to measure dry ingredients like flour, nuts, and berries, while liquid measuring cups are designed to measure liquids like water, cooking oil, and yogurt.

## What is SI unit of electric resistance?

The SI derived unit of electric resistance is the ohm, which is defined as a volt per ampere. A statcoulomb is defined as ohms where c is the magnitude of the speed of light, and is energy-equivalent to the unit second per centimeter (). A preece is defined as ohms.
