Explanation
The quantity of matter in a body is called its mass . while  Force is a push or pull acted on an object . Weight is the measure of the force exerted on the mass of the body due to gravity.

Explanation
The SI unit of volume is the cubic meter (m3), which is a derived unit. 1 m3 = 1 m • 1 m • 1 m. *** The  SI unit  of energy/work is the  joule (J) The SI unit of charge is Coulomb The Pascal is the SI-derived unit of pressure The ampere,  symbol A , is the SI unit of  electric current. The SI unit of power  is the watt, one joule per  second. The SI unit of  electric resistance  is the  ohm (Ω). The  SI unit  of temperature as per the International System of Units is  Kelvin   Unit of torque: newton metre ( N m ) The SI unit of velocity is a meter per  second (m/s). The SI unit of acceleration is  meters/second2 (m/s2)

Explanation
The Metric System of Measurements uses the mass units: gram (g), kilogram (kg) , and tonne (t). 1000 g = 1 kg. 1000 kg = 1 tonne. Mass was first defined in 1795 Symbol : M

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
The SI unit of velocity is a  ms^-1 and m/s. Common symbols v ,  v ,  v → ,  v

Explanation
In the metric system, the SI unit of length is a meter which is defined as: “The length of the path traveled by light in a vacuum within 1⁄299792458 seconds .” Common symbols : l ND18-9-2023

Explanation
The hottest stars appear blue in color. Blue stars are very hot, with surface temperatures reaching tens of thousands of degrees Celsius. It emitting predominantly blue and ultraviolet light.

Explanation
The  nucleus , formed by a  nuclear membrane  around a  fluid nucleoplasm,  is the  control center  of the cell. Threads of  chromatin  in the nucleus contain  deoxyribonucleic acid (DNA) , the  genetic material  of the cell.

Explanation
the direction of the magnetic field lines gets reversed when the direction of the current flowing through the conductor is reversed.

Explanation
Sound energy is the energy created by the vibration of particles , such as molecules or atoms, as they oscillate back and forth. This vibration creates a disturbance that travels through a medium , like air, water, or solids, and is perceived as sound.
