Explanation

The SI unit of velocity is a ms^-1 and m/s.

Explanation

The tesla is the unit of magnetic flux density (also called magnetic B-field strength)

One tesla is equal to one Weber per square meter.

Unit system: SI

Symbol: T

Named after: Nikola Tesla

Explanation

Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.

 chemical formula of SiO2

Explanation

The cell constant is a measure used in conductivity measurements and is defined as the ratio of the distance between the electrodes to the area of the electrodes.

Its unit is cm⁻¹ (inverse centimeters), which reflects the geometric configuration of the cell used in measuring conductivity.

Explanation

10^-12: Picosecond (ps)

10^-6: Microsecond (μs)

10^-9: Nanosecond (ns)

10^-3: Millisecond (ms)

10^-18: Attosecond (as)

10^-15: Femtosecond (fs)

10^-21: Zeptosecond (zs)

10^-24: Yoctosecond (ys)

Explanation

Light Year is the distance that light can travel in one year.

The distance light travels in one year is known as light year.

Explanation

The SI unit of acceleration is meters/second^2 (m/s^2 or ms^-2)

Acceleration (a) is defined as the rate of change of velocity.

Velocity is a vector quantity, and therefore acceleration is also a vector quantity.

Explanation

Steel, being a solid metal, is measured by weight.

The standard unit for measuring steel is kilograms or tons, depending on the quantity.

Explanation

Light emitting diode is a 2 lead semiconductor device . 

Explanation

 Electric lines of force are always diverging from positive charge and they converge at a negative charge.
