Explanation

Electric power: Rate of energy transfer.

It is measured in watts (W), or one joule per second.

Energy/Work: Measured in joules (J).

Charge: Measured in coulombs (C).

Pressure: Measured in pascals (Pa).

Electric current: Measured in amperes (A).

Electric resistance: Measured in ohms (Ω).

Temperature: Measured in kelvin (K).

Torque: Measured in newton metres (N m).

Velocity: Measured in meters per second (m/s).

Acceleration: Measured in meters per second squared (m/s²).

Explanation

SI (International System of Units) fundamental units include meter (length), kilogram (mass), and second (time).

All other units like Newton, Joule, etc., are derived from these base units.

Explanation

The SI unit of pressure is Pascal (represented as Pa) 

in SI base units, one kilogram per meter per second squared (N/m2 or kg m-1s-2)

Definition of Pressure: Pressure can be defined as the force acting per unit area.

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

Antoine Henri Becquerel was an engineer, physicist, Nobel laureate,

First person to discover evidence of radioactivity.

 He belonged to France.

Explanation

The SI unit of electric charge is the coulomb, represented by the symbol C.

One coulomb is the amount of charge that passes through a conductor carrying one ampere of current for one second.

It's also equal to the charge of about 6.24 quintillion electrons or protons.

Explanation

The ampere, symbol A, is the SI unit of electric current.

It is defined by considering the fixed  value of the elementary charge e as 1.602 176 634 x 1019,

where the unit C is equal to As and the second is defined by Δν Cs.

Explanation

• Weight is a force.
• The unit of measurement for force is the Newton (N).

Explanation

Explanation

Poison dosage is measured in milligrams (mg) based on body weight.

Even a small variation in mg can determine whether a substance is safe or toxic.
