Answer:

Option (B)

Explanation:

Asteroids are the rocky materials that are present abundantly in an orbit between the planet Mars and Jupiter. This is known as the asteroid belt, which is comprised of millions of asteroids that move around the sun. They are of various sizes ranging from a few meters to about hundreds of kilometers, which can cause mass extinction if strikes on the surface of the earth. They move at a speed of about 80,000 km/hr and during this motion, frequent collision takes place and they are considered to be the remnant of the early solar system.

Thus, the correct answer is option (B).

The force exerted by the first object on a second object is known as the action force, a part of Newton's Third Law of Motion, which states that equal and opposite forces are exerted on both objects involved in an interaction.

The name given to the force exerted by the first object on a second object is generally referred to as the "action" force. This is a part of Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. This law means that whenever one body exerts a force on a second body, the second body simultaneously exerts a force that is equal in strength and opposite in direction to that of the first body.

This concept is significant because it underlines the symmetry of forces in nature. When object A exerts a force on object B, object B exerts a force back on object A. These forces are equal in magnitude but opposite in direction, reflecting Newton's Third Law which is often informally referred to as the law of action and reaction.

The correct statement is Material D is denser than Material A.

What is density of a material

Density of a material represents the amount of mass contained within a specific volume of that substance. It is calculated by dividing the material's mass by its volume.

This fundamental property, denoted as  ρ, varies based on the composition and structure of the substance. For instance, metals generally possess higher densities compared to gases or liquids.

Hence we can say that Material D is denser than Material A.

No, if velocity becomes too great, the planet can escape the Sun's gravitational pull.

Explanation:

It is correct on Edge 22

Answer:

b. when the sun, Earth, and the moon are nearly in a line

Explanation:

Due to gravitational pull of sun and moon, the level of water in seas and oceans rises above its normal level. This is known as tides. Highest tides occur when the sun, the moon and the Earth align in a straight line i.e. during New moon and Full moon. This is because in this alignment, there is maximum effect of gravity. Tide occurrence during this phase are also referred as spring tides.

The speed of a wave with a frequency of 8,500 Hz and a wavelength of 1.5 m is calculated as 12,750 m/s by multiplying the frequency and wavelength together.

To calculate the speed of a wave, we can use the formula v = f × λ, where v is the speed of the wave, f is the frequency, and λ (lambda) is the wavelength. Given that the frequency, f, is 8,500 Hz and the wavelength, λ, is 1.5 m, you can plug these values into the equation to determine the wave's speed.

Speed of the wave v = 8,500 Hz × 1.5 m = 12,750 m/s

So, the speed of the wave with a frequency of 8,500 Hz and a wavelength of 1.5 m is 12,750 meters per second (m/s).

Answer:

Potential energy is the energy possessed by a body at rest while kinetic energy is the energy possessed by a body in motion.

Explanation:

Potential energy is the energy possessed by a body by virtue of its position while kinetic energy is the energy possessed by a body by virtue of its motion. Potential energy is the energy acting on a body at rest(not moving) while kinetic energy is the energy acting on moving object(motion).

Example of potential energy is the energy possessed by a parked car. The parked car is not moving i.e the car is in a state of rest

Example of kinetic energy is the energy possessed by an accelerating car. The car is in motion (moving).

The hammer pounding a nail demonstrates Newton's First Law, as the hammer's horizontal motion stops due to the opposing force of the nail and board, and Newton's Third Law, with the nail applying an equal and opposite force to the hammer.

The phenomenon of a hammer pounding a nail into a board can be analyzed using Newton's laws of motion. Specifically, two of these laws are demonstrated:

Newton's First Law (also known as the law of inertia). This law suggests that if an object is in motion, it will not change its velocity unless a force acts upon it. For example, a hammer in motion strikes a nail and is brought to rest because the nail and board apply a force opposing the hammer's motion.

Newton's Third Law states that for every action, there is an equal and opposite reaction. Therefore, as the hammer applies a force to drive the nail into the board, the nail applies an equal and opposite force to the hammer, causing it to stop.

When a hammer hits a nail, the horizontal momentum of the hammer is reduced to zero as the nail stops the hammer—illustrating Newton's First Law. Simultaneously, the force with which the hammer strikes the nail and the nail’s force on the hammer (which is responsible for stopping the hammer) is an example of Newton's Third Law in action.

sound waves and light waves are both types of waves that exhibit similar behaviors such as reflection, refraction, and interference. However, they differ in their physical properties such as the medium they travel through, their speed, and their frequency.

Sound waves and light waves are both types of waves that propagate through a medium, but they have several differences in their physical properties and behaviors.

Physical Properties:

1. Medium: Sound waves require a medium to travel through, such as air, water, or solids. Light waves, on the other hand, can travel through a vacuum and do not require a medium.

2. Speed: Sound waves travel at a slower speed than light waves. The speed of sound waves depends on the density and compressibility of the medium through which they are traveling. In contrast, the speed of light waves is constant in a vacuum and is one of the fundamental constants of nature.

3. Frequency: Sound waves have lower frequencies than light waves. The frequency of a sound wave is the number of cycles per second, measured in hertz (Hz). Light waves have much higher frequencies, typically measured in terahertz (THz).

Behaviors:

1. Reflection: Both sound waves and light waves can reflect off surfaces. When a sound wave reflects off a surface, it changes direction, and the angle of incidence is equal to the angle of reflection. When a light wave reflects off a surface, it undergoes a change in direction and can be either specular (like a mirror) or diffuse (like a matte surface).

2. Refraction: Both sound waves and light waves can be refracted or bent when they pass through a medium with a different density. When a sound wave is refracted, it changes direction and speed, while when a light wave is refracted, it can change direction, speed, and wavelength.

3. Interference: Both sound waves and light waves can exhibit interference when two or more waves combine to form a resultant wave. In sound waves, interference can be constructive, where the amplitudes of the waves add together, or destructive, where the amplitudes cancel each other out. In light waves, interference can be either constructive, where the waves add together to create bright fringes, or destructive, where the waves cancel each other out to create dark fringes.

Therefore, sound waves and light waves are both types of waves that exhibit similar behaviors such as reflection, refraction, and interference. However, they differ in their physical properties such as the medium they travel through, their speed, and their frequency.

Answer:

Light energy is absorbed by plants and converted to chemical energy.

Explanation:

The loudness of a sound can be increased by increasing the amplitude of the sound wave. This can be achieved by adjusting the volume on a speaker or by using devices designed to amplify sound, like a vuvuzela. Also, sounds with higher amplitude and intensity, such as those from a loud car stereo, are naturally louder.

The loudness or volume of a sound wave can be increased by increasing its amplitude. The amplitude of a sound wave determines how much energy it carries, which directly affects its loudness. An example of this is how a speaker produces louder sounds: as you increase the volume on a speaker, it causes the table or surface it is on to vibrate more vigorously. This is because the speaker is moving more air (higher amplitude), which translates to a louder sound.

Another example is using a vuvuzela. The size and construction of the vuvuzela are designed to amplify the sound produced by the person blowing into it, making it louder. The amplified sound has a higher amplitude and therefore a louder volume.

Finally, in a real-life scenario, consider two sounds: one from a passing car's stereo and the other from the person next to you. The sound from the car's stereo is amplified due to its higher intensity and amplitude, making it louder and causing it to dominate over the sound coming from the person next to you.

Newton's Second Law of Motion which states that the acceleration an object experiences is directly proportional to the force applied to it

The FIRST law states that an object at rest stays at rest, or if it's moving it continues at a consistent speed and direction unless acted on by another force. The SECOND law implies that the force needed to change an object's motion depends on its mass and the required acceleration. The THIRD law states that every force (action) has an equal and opposite force (reaction).

Newton's FIRST Law of Motion

An object at rest stays at rest, or an object that is moving at a consistent speed in a straight line keeps moving at that speed unless another force acts on it.

Newton's SECOND Law of Motion

The amount of force needed to make an object change its motion depends on the mass of the object and the acceleration required.

Newton's THIRD Law of Motion

For every action (or force), there is a(n) equal and opposite reaction (or force).

Thermal energy is defined as the kinetic energy present within the particles of a substance.

A process in which energy is absorbed by the molecules of a substance is known as endothermic process. On the other hand, a process in which energy is released by the molecules of a substance is known as exothermic process.

Condensation : A process in which vapors change into liquid as bonds are formed and energy is released.

Freezing : A process in which liquid changes into solid as bonds are formed and energy is released.

Deposition : A process in which particles of a substance come closer to each other resulting in bond formation and release of energy.

Sublimation : A process in which solid state directly changes into gaseous state without undergoing liquid state is known as sublimation. In this process, bonds break and energy is absorbed by the solid particles.

Evaporation : A process in which liquid changes into gas as energy is absorbed leading to breakage bond.

Melting : A process in which solid changes into liquid as energy is absorbed leading to breakage bond.
