The Kinetic Theory of Matter states that the particles that make up all matter are in perpetual motion. We know that a solid can

not change shape because its constituent particles are unable to change position. Explain how the particles that make up solid matter can be in perpetual motion if they do not change position.
Describe how the Kinetic Theory of Matter defines heat and how heat is affected by the rate of movement of the particles that make up matter.

Answer:

Explanation:

1 : As we know solid do not change their shape and sizes as the molecules in them are tightly packed and have very little inter molecular spacing in between, they cannot leave there area and move outside but they tends to keep on vibrating from there mean position hence they do perpetual motion.

2: As per Kinetic theory of matter, it states that matter is made up of small particles that are in constant motion. Heat increases the rate of movement of particles as when heat is provided the particles tends to acquire energy and start vibrating more rapidly. Hence applied heat is directly proportional to the rate of movement of particles.

<span>1) Explain how the particles that make up solid matter can be in perpetual motion if they do not change position.  Answer: they do not mov, just vibrate a bit more and move further apart. And as a result solid expand a bit.

</span><span>2) How the Kinetic Theory of Matter defines heat. Answer: Heat is a form of energy that particles convert into kinetic energy. Adding a heat energy increases the kinetic energy of particles. This means that as a substance is heated - the particles vibrate faster and move further apart. </span>

8. John has to hit a bottle with a ball to win a prize. He throws a 0.4 kg ball with a velocity of 18 m/s. It hits a 0.2 kg bott
nasty-shy [4]

<u>Answer:</u> The ball is travelling with a speed of 5.5 m/s after hitting the <u>bottle.</u>

<u>Explanation:</u>

To calculate the speed of ball after the collision, we use the equation of law of conservation of momentum, which is given by:

m_1u_1+m_2u_2=m_1v_1+m_2v_2

where,

m_1,u_1\text{ and }v_1 are the mass, initial velocity and final velocity of ball.

m_2,u_2\text{ and }v_2 are the mass, initial velocity and final velocity of bottle.

We are given:

m_1=0.4kg\\u_1=18m/s\\v_1=?m/s\\m_2=0.2kg\\u_2=0m/s\\v_2=25m/s

Putting values in above equation, we get:

(0.4\times 18)+(0.2\times 0)=(0.4\times v_1)+(0.2\times 25)\\\\v_1=5.5m/s

Hence, the ball is travelling with a speed of 5.5 m/s after hitting the bottle.

Whats the speed of darkness?
lianna [129]
The same speed of light, the fastest possible

darkness is just the absence of light therefore once light leaves darkness returns. making darkness have the same speed of light

A wave is traveling through a medium. As it travels, it displaces particles of matter in the same direction as the wave is trave
Alexxandr [17]

<u>Answer</u>

longitudinal wave because the particles move parallel to the direction that the wave is traveling.


<u>Explanation</u>

There are 2 types of a wave, electromagnetic and mechanical wave. These waves can also be categorized into two, longitudinal ans transverse waves.

longitudinal wave is a wave whose particles vibration is in the direction of wave travel.

Transverse wave is a wave whose vibration of particles is perpendicular to the direction of wave travel.

On a roller coaster, describe the kinetic and potential energy of the car at the top of the first hill, the bottom of the first
vaieri [72.5K]
The total amount of energy stays the same, but throughout the ride, the kinetic energy and the potential energy change, still adding up to the same number. At the top of the ride it has potential energy, and as it goes down the potential energy decreases and the kinetic energy increases. When it’s at the bottom of the first drop it has maxed out its kinetic energy, and minimized its potential energy. Friction slows down the car, and pushes on the cart with a force that is equal and opposite to the force being exerted in the track. The reason the track keeps going is because though it exerts and equal and opposite force the momentum of the objects is different, allowing the car to continue moving, however friction will slow it down until eventually it comes to a stop.

The following forces act on an object: 10 N north, 7 N south, and 4 N east. What is the magnitude of the net force?
spin [16.1K]

Given data;

 Fn = 10 N

 Fs = 7 N

 Fe = 4 N

           force in X direction (Fx) = 4 N

           force in Y direction (Fy) = 10-7 = 3 N

           Net force (Fnet) = Sq.root[(Fx)² + (Fy)²]

                                      = Sq root [ 4² + 3² ]

                                      = 25 N

        <em> Net force acting = 25 N</em>
