Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. C

Answer 2

$\large\underline{ \underline{ \sf \maltese{ \: Question⤵ }}}$

➡ Explain the universal law of gravitation.

❇ AnsWer ⬇

The Universal Law of Gravitation states-

‎ ❝Every object of mass in the Universe attracts every other object of mass with a force which is directly proportional to the product of their masses and inversely proportional to the square of the separation between their centres.❞

Additional Information ⬇

$\large{\huge{\underline \mathbb{ \overline { \mid{ \blue{Fg = G m1 m2/r² } \mid}}}} }$

Where,

Fg is the gravitational force.

m1 & m2 are masses of the two objects.

r is the distance between two objects.

G is the universal gravitation constant.

Thank you.
