Answer:
Log burning in a fire. Burning wood is an example of a chemical reaction in which wood in the presence of heat and oxygen is transformed into carbon dioxide, water vapor, and ash.
Explanation:
Depends on the structural integrity of the solid. We can use a subwoofer speaker for example; technically its a solid that could influence sound waves.
So basically, sound could travel through solids but, you need to know the thickness, mass and density of that solid; in-order to make conclusions.
Van der Waals are weak, short-range electrostatic attractive forces between uncharged molecules, arising from the interaction of permanent or transient electric dipole moments.
D.When the forces are stronger, the melting point of a substance will be lower.
Given :
Force applied on book, F = 18 N.
Kinetic friction, .
Mass of book, M = 3 kg.
To Find :
The acceleration of book.
Solution :
Equation of force applied on book is :
Therefore, acceleration of book is 2 m/s².
Hence, this is the required solution.
