A mechanical wave is a disturbance in matter that transfers energy through the matter.
Mechanical waves require a medium to travel through, such as a solid, liquid, or gas.
Mechanical waves require a medium through which they can travel. The medium can be a solid, liquid, or gas. Examples of mechanical waves include water waves, sound waves, and seismic waves.

An increase in thermal energy causes molecules to move more rapidly and vibrate more quickly. Higher temperatures affect the distribution of kinetic energies and can cause phase changes.
When thermal energy increases, molecules gain more kinetic energy and therefore move more rapidly. This increased kinetic energy causes molecules to vibrate more quickly. As a result, the temperature of the substance increases. Higher temperatures also affect the distribution of kinetic energies among the molecules in a substance. At higher temperatures, more molecules have the necessary kinetic energy to escape from a liquid to the gas phase.
Additionally, increasing thermal energy can cause phase changes in a substance, such as melting or vaporization, where additional energy is used to loosen bonds between molecules or atoms without changing the temperature. Thus, adding thermal energy can lead to the melting or vaporization of a substance.

Using a ruler, determine the scale used in the vector diagram.
The resultant of the force is 100 Newton in the direction of 36.90°.
A physical quantity that has both directions and magnitude is referred to as a vector quantity.
A lowercase letter with a "hat" circumflex, such as "û," is used to denote a vector with a magnitude equal to one. This type of vector is known as a unit vector.
Let's learn vector addition and subtraction after first learning what a vector is. The simple arithmetic principles are not followed when adding or subtracting vector values. The addition and subtraction of vectors are conducted in accordance with a unique set of guidelines.
Given:
Force F₁ = 60 Newton east
Force F₂ = 80 Newton north
The resultant of the force is = √((60)² + (80)²) Newton = 100 Newton.
The direction of the force is = tan⁻¹(60/80) = 36.90°
