Answer: Differences: Solids have particles that are tightly packed and they form a pattern. In this case, they move and vibrate in place. On the other hand, liquid particles are close together but they have an irregular arrangement. The spaces between the particles allow them to move freely.

Explanation:

Particles in solids are arranged in a pattern and are closely packed. In this instance, they remain stationary and vibrate. However, despite being close together, liquid particle arrangements are asymmetrical. The particles can travel freely because of the voids between them and the similarity is both solid and liquid has some shape, but gas does the random movement in the container.

In solid the particles are tightly packed with each other, so there will be no such movement by the particles it means that there the particles have very less kinetic energy. Solids have definite shape and size, and they are incompressible in nature, and they are tough and rigid as well.

In liquid the particles are lightly packed with each other due to which there is some movement in the particles it means that the particles have some kinetic energy. The liquids are compressible in nature. They do not have a specific shape, but they can take the shape of a container where it is filled.

Liquids are fluid in nature.

In gases, there is so much of  distance between particles due to which the particles do random movement, and they have high kinetic energy. They do not have any shape and size, but they are highly compressible as compared to solid and liquid. They also take the shape of the container where they filled.

Answer:

\(Force = 13.8N\)

Explanation:

Given

\(Mass = 0.6kg\)

\(Acceleration = 23m/s^2\)

Required

Determine the applied force

From the question, we understand that no other force acts on the ball.

i.e. the only applied force on the ball is the force applied by the striker.

So, we apply Newton's second law to solve this question.

And this implies that:

\(Force = Mass * Acceleration\)

\(Force = 0.6kg * 23m/s^2\)

\(Force = 13.8N\)

Hence, the applied force by the striker on the ball is 13.8N

1. When a cold air mass and a warm air mass meet but are at a standstill, the boundary is called stationary front.

2. If warm or more humid air presses forward and colder or drier air draws back, the boundary is called warm front.

3. If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called cold front.

4. Sometimes a warm air mass can get caught between two cold fronts, which can force the warm air up into a wedge shape is called occluded front.

Explanation:

A stationary front is created when two air masses of different temperatures come together but remain stationary. A warm front is created when warmer, more humid air pushes forward and cooler, drier air pulls back.

A front in a physical system can be thought of as the boundary between two distinct possible states (either stable or unstable). When two air masses with different temperatures come together but stay stationary, a stationary front is formed.

Explanation:

The total distance in the horizontal direction traveled by Danger Dog can be calculated using the following equation:

\( x_{f} = x_{0} + v_{0_{x}}t + \frac{1}{2}at^{2} \)   (1)

Where:

\( x_{f}\): is the final position in the horizontal direction =?                                      

\(x_{0}\): is the initial position in the horizontal direction = 0                                      

\( v_{0_{x}} \): is the initial velocity in the horizontal direction = 32 m/s

t: is the time

a: is the acceleration = 0 (he is accelerated only by gravity)

So, we need to find the time. We can find it as follows:

\( y_{f} = y_{0} + v_{0_{y}}t - \frac{1}{2}gt^{2} \)    (2)

Where:

\( y_{f}\): is the final position in the vertical direction = 0                                      

\(y_{0}\): is the initial position in the vertical direction = 45 m                                      

\( v_{0_{y}} \): is the initial velocity in the vertical direction = 0

g: is the acceleration due to gravity = 10 m/s²      

By solving equation (2) for "t" we have:

\( t = \sqrt{\frac{2(y_{0} - y_{f})}{g}} = \sqrt{\frac{2*45 m}{10 m/s^{2}}} = 3 s \)

Hence, the total distance traveled by Danger Dog in the x-direction is (equation 1):

\( x_{f} = 32 m/s*3 s = 96 m \)    

Therefore, the correct answer is b: 96 m.

The density of ceramic statue was found to be 2500kg/m³

First we calculate amount of water displayed

=  28.4 - 17.0 = 11.4N of water displaced.

Now, we calculate the volume of water displayed ,

Volume=water displaced /gravity

=11.4/9.8

Volume = 1.16kg of water.

we know that, density of water = 1000kg/m³

so, density of 1.16 kg= 1.16 x10^-3 m^3

mass of ceramic statue= 28.4 N/9.81 kg = 2.90 kg.

At last we calculate, density of ceramic statue by,

density of ceramic statue = ceramic mass/ density of water

= 2.90/(1.16 x 10^3) = 2500kg/m³

Thus, the density of ceramic statue is found to be 25kg/m³.

When waves move from deep water to shallow water, the velocity of the waves decreases. The distance between the wave crest and the seabed decreases in shallow water, making it more challenging for the wave to move forward. As a result, the speed of the waves slows down.The waves bend as they come across the shallow water region because the water depth varies.

As a result, the wave front becomes warped resulting in a decrease in speed. As the wave enters shallow water its wavelength becomes shorter and its amplitude increases, but its frequency remains constant.The wave's velocity changes depending on the medium's density.

The denser the medium, the slower the wave travels, and vice versa. Since the speed of sound in water is quicker than that in air, sound waves travel faster through water than they do through air. As a result, the answer to the question is that the waves move slower through the second medium.

In the shallow water area, waves slow down and their shape changes. The energy of the wave is forced upward and outward, causing the wave to break. At the edges of the shallow area, the waves bend and change direction. As the waves come closer to shore, their circular motion causes them to collide with one another and pile up.

As a result, the waves become higher and steeper, resulting in a more turbulent environment for boats and swimmers.

According to the question the force acting on the plane id 547,750 N.

Force is a fundamental concept in physics that describes the interaction between two objects. It is defined as an influence that changes the motion of an object, either by accelerating, decelerating, or changing the direction of a body. Forces can be either contact forces, such as friction or air resistance, or non-contact forces, such as gravity or magnetism. Forces can also be internal, such as chemical bonds, or external, such as the force of an object pushing against another. The SI unit for force is the newton (N). Forces can be used to cause motion or to prevent motion. In addition, forces can be used to change the shape or orientation of an object. Force is a vector quantity, meaning that it has both magnitude and direction.

The force acting on the plane can be calculated using Newton's second law:

Explanation:

Frost typically forms on the inside surface of a windowpane (rather than the outside) because the interior of a room is usually warmer and more humid than the exterior.

When the temperature drops below freezing outside, the warm and humid air inside the room comes into contact with the cold windowpane. This causes the moisture in the air to condense and freeze on the glass, forming frost. Since the outside temperature is already cold and dry, there is no additional moisture in the air to create frost on the outside of the window.

The inside surface of a windowpane becomes colder than the outside surface due to the difference in temperature between the indoor and outdoor environments. When the warm, moist air inside the room comes into contact with the colder surface of the windowpane, the moisture in the air condenses and freezes, forming frost on the inside of the windowpane. This occurs because the air can no longer hold as much moisture when it is cooled, causing the excess water vapor to change from gas to solid state (frost).
