Define s. i unit of force explanation

◈ As per newton's second law of motion, Force is defined as the product of mass and acceleration

Mathematically,

Unit of mass : kg

Unit of acceleration : m/s²

Therefore,

Unit of force ➠ kg m/s²

SI unit : N (newton) or kg m/s²

measure their densities same density, same sub

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
