Describe the change in motion and kinetic energy of the particles as thermal energy is added to a liquid. Which change of state
lions [1.4K]
If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.

Answer:

Centripetal force is the force that is necessary to keep an object moving in a curved path and that is directed inward towards the center of rotation.

Explanation:

Definition of centripetal force:

Centripetal force is the force that is necessary to keep an object moving in a curved path and that is directed inward towards the center of rotation.

Example of centripetal force

A string on the end of which a stone is whirled about exerts a centripetal force on the stone.

The diagram is shown below

Where

The centripetal forces acting towards the centre C that is \vec {AC}

and the direction is from A to C.

And the stone is moving in a circular motion with center as C.

Three deer, a, b, and c, are grazing in a field. deer b is located 64.9 m from deer a at an angle of 53.4 ° north of west. deer
Levart [38]
Make an illustration of the problem to aid you in analyzing your approach to solve this. As seen on the picture, it forms a triangle. Since the total interior angles of a triangle is equal to 180°, then the missing angle would be: 180 - 53.4 - 77.9 = 48.7°. Applying the Cosine Law,

x² = 64.9² + 96.8² - 2(64.9)(96.8)(cos 48.7°)
x = √5289.567
x = 72.7 meters
