Question

definition of mitre,k.g,second,ampere,kelvin,mole,candela,

Answer 1

Answer:

1. Meter : The meter, symbol m, is the SI unit of length.

2. Kilogram : Kilogram (kg), basic unit of mass in the metric system.

3. Second : Second is defined by taking the fixed numerical value of the caesium frequency ∆ν, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s−1.

4. Ampere : An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor.

5. Kelvin : Kelvin, base unit of thermodynamic temperature measurement in the International System of Units ( S.I.).

6. Mole : A mole is the amount(10) of material containing 6.02214 × 1023 particles. 1 mol = 6.02214 × 1023 particles.

7. Candela : The SI unit of luminous intensity. One candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 × 1012 Hz and that has a radiant intensity in that direction of 1/683 watt per steradian.
