what happens when light is scattered?

Answer:

B. 34.78 m/s

Explanation:

The momentum of an object is given by:

[tex]p=mv[/tex]

where

p is the momentum

m is the mass of the object

v is its velocity

For the object in this problem, we have

p = 4000 kg m/s

m = 115 kg

So, we can solve the equation to find v, the velocity:

[tex]v=\frac{p}{m}=\frac{4000 kg m/s}{115 kg}=34.78 m/s[/tex]

B. Universal Gravitational Law

Answer:

B. Universal Gravitational Law

Explanation:

As we know that Kepler gives three laws regarding the planetary motion of all planets around the sun

All his laws are derived from the basic Theory of law of attraction by gravitation.

Universal law of attraction given by Sir Issac Newton says that if two masses are placed at some distance from each other then the net force between two masses is given as

[tex]F = \frac{Gm_1 m_2}{r^2}[/tex]

here we know that

[tex]m_1, m_2[/tex] = masses of two objects

[tex]r [/tex] = distance between two objects

Final answer:

The period of a wave with a frequency of 387 Hz is found by taking the inverse of the frequency, which yields approximately 0.00258 seconds or 2.58 milliseconds.

Explanation:

The student has asked what the period of a wave with a frequency of 387 Hz is. The period (T) of a wave and its frequency (f) are inversely related. The relationship between period and frequency is given by the formula T = 1/f. So, to calculate the period of a wave with a frequency of 387 Hz, we divide 1 by the frequency.

T = 1/f = 1/387 Hz

When we do the calculation, we find that the period T is approximately 0.00258 seconds, or 2.58 milliseconds.

This concept is central to understanding wave dynamics and is used in various applications, including communications, engineering, and the sciences.

Gravity is the pulling force on the skydiver while air resistance is the pushing force. If there were no air resistance, the skydiver would fall straight to the ground and may not have enough time to pull the parachute, and if there were no gravity, the skydiver would probably just float in place (weird, right?) The force of gravity is stronger than the air resistance, however. That's why the skydiver will fall out of the plane toward the ground. Once the parachute is deployed, there is more area for air resistance to take hold. The parachute will slow the skydiver to make for a much safer landing.

Explanation:

rotational inertia would be the right answer

The resistance of a rotating body to changes in angular velocity called rotational inertia

Answer: Option B

Explanation:

The rotational inertia of a rotating object resist the changes in the angular velocity of the object.  Whenever we try to reduce the velocity of a rotating object or try to stop its motion, we feel a force or kind of resistance in its nature.

This is because an object which rotates through an axis follows the law of inertia exerting a resistance against the external force which tries to change its motion or simply the angular velocity.

Heavier bodies have more rotational inertia as compared to the lighter ones because of its mass. This kind of inertia is known as the “Moment of Inertia” formulated as,

              [tex]J_{0}=\sum m_{i} r_{i}^{2}[/tex]

Where,

[tex]J_{0}[/tex] - Moment of Inertia

Hurricanes are intense storm in tropic regions. When hurricane makes landfall it will loss its strength and weakens . Hence option A is correct.

Hurricanes are powerful storms with a tropical origin. Small groups of disorganized storms that collect energy from the heat of the ocean water are the precursors to hurricanes.

Individual clouds will start to group together into a single storm if specific atmospheric conditions are met. The organization of the cloud clusters will intensify, and the winds will pick up and move around a particular point, the eye, if the storm keeps consuming heat from the ocean.

It is also recognized that hurricane-related extreme atmospheric conditions can give rise to tornadoes. Because they are no longer able to draw energy from the ocean when a storm makes landfall, they start to weaken. They can still harm a lot and are harmful nonetheless.

What happens when a hurricane makes a landfall; it weakens. This makes option A the right choice.

When a hurricane makes landfall, several things typically happen:

A. A hurricane will weaken after making landfall: This statement is generally true. When a hurricane moves over land, it loses its primary energy source, which is the warm ocean waters. As a result, the storm's strength tends to diminish gradually as it moves farther inland. However, hurricanes can still cause significant damage even after making landfall, especially if they are large and powerful at the time of landfall.

B. A hurricane will pick up speed after making landfall: This statement is not accurate. Once a hurricane makes landfall, it usually begins to slow down as it interacts with the friction and topography of the land. The storm's forward speed typically decreases as it moves inland.

C. A hurricane will have stronger wind speeds after it makes landfall: This statement is generally not true. As mentioned earlier, a hurricane weakens after making landfall due to the loss of its primary energy source, warm ocean waters. Wind speeds tend to decrease as the storm moves over land.

D. A hurricane will have a smaller storm surge after it makes landfall: This statement is generally true. Storm surge is the rise in sea level generated by a hurricane's winds and low pressure. When a hurricane moves over land, its ability to push seawater ashore diminishes, resulting in a reduction in the storm surge. However, storm surge can still be a significant threat near coastal areas even after a hurricane makes landfall.

Memories occur when specific groups of neurons are reactivated. In the brain, any stimulus results in a particular pattern of neuronal activity—certain neurons become active in more or less a particular sequence.

Explanation:

Hope this helps

Integration of stimuli and comparison with memories and previous stimuli leads to specific responses. Behaviors can be instinctual or learned, depending on the influence of the environment.

Integration. Stimuli that are received by sensory structures are communicated to the nervous system where that information is processed. This is called integration. Stimuli are compared with, or integrated with, other stimuli, memories of previous stimuli, or the state of a person at a particular time. This leads to the specific response that will be generated. For example, when seeing a baseball pitched to a batter, the trajectory of the ball and its speed will be considered before the batter decides to swing.

Behaviors can result from this integration of stimuli. They can be instinctual or learned. Instinctual behaviors are not influenced by the environment and include mating systems and methods of communication. On the other hand, learned behaviors are influenced by the environment and include imprinting, habituation, conditioning, and cognitive learning.

Final answer:

Both concave (diverging) and convex (converging) lenses can produce virtual images; concave lenses always create a smaller virtual image, while convex lenses do so when the object is closer than the lens's focal length.

Explanation:

A virtual image is formed when the light rays coming from an object appear to diverge after passing through a lens. A virtual image is one where the rays only seem to have crossed behind the lens, and this image cannot be projected onto a screen as it doesn't exist at a point in space where light actually converges. There are two types of lenses that can produce virtual images. A concave lens, also known as a diverging lens, always produces a virtual image that is smaller than the object. On the other hand, a convex lens or converging lens can produce a virtual image when the object is placed at a distance less than its focal length (d° < f), in which case the virtual image is larger than the object. In summary, both concave and convex lenses can produce virtual images under specific conditions.

Earth's gravity attempts to change the velocity of all objects on Earth's surface toward the center of the Earth at a rate of 9.8 meters per seconds squared.

Explanation:

Answer:

Earth's gravity attempts to change the velocity of all objects on Earth's surface toward CENTER OF EARTH at a rate of 9.8 meters per seconds squared.

Explanation:

As we know that the gravitational force of Earth is towards the center and it is given by the formula

[tex]F = \frac{GMm}{R^2}[/tex]

this is the force experienced by all the objects near the surface of Earth and this force is towards the center of the Earth

So this is also know as gravity of Earth

Now we know that the acceleration of objects near the surface of Earth is given by the equation

[tex]a = \frac{F}{m}[/tex]

[tex]a = \frac{GM}{R^2}[/tex]

this is also known as acceleration due to gravity and this is of magnitude g = 9.8 m/s/s

so all objects will move towards the center of earth with rate of change in velocity of 9.8 m/s/s

Answer:Heavy rain,Strong winds,Severe lightening

Heavy rain, strong winds and severe lightning are the events which can cause damage during thunderstorm.

Answer: Option A, D and E

Explanation:

Thunderstorm is term given to occurrence of heavy rains accompanied by high sounds and lightening. As the sound is produced due to lightening, that sound is termed as thunder and the presence of heavy rain is termed as storm.

So both together is termed as thunderstorm. Thunderstorm usually occurs due to increase in moisture, temperature and when the heated air molecules are raised upward. During these thunderstorms, the occurrence of heavy rains, flow of strong winds and severe lightening are well known.

So heavy rains can lead to flash flooding and destruction of homes, strong winds will also lead to damage of objects and lightening may cause forest fire. Thus these three events during thunderstorm causes damage.

Explanation: The book begins by starting off with the life story of Willie Chandran's dad, in India. Willie Chandran's father was part of an affluent family with positions high up in the government, starting from when his grandfather first landed a job working for the king, which was then succeeded by that grandfather's son, which was finally supposed to be succeeded by Willie Chandran's dad. However, Willie Chandran's dad was not content with this bland life of government work in the tax office, despite the numerous promotions he was receiving on the basis of his father's name. He was even supposed to be married to the daughter of the principal at an extremely prestigious school. This too meant nothing to him. What really mattered was the independence movement taking place across the country, led by Mahatma Gandhi. Heeding the calls of Mahatma Gandhi, Willie Chandran's dad decided to break from his family's heritage and married a poor woman of low caste. This leads to the birth of Willie and his sister Sarojini.

This union led to a life of regret for Willie Chandran's dad and Willie. He grew up ashamed of his family background and despised his father for his character. Willie loved his mother but soon even that relationship started to distance itself. At 18, struggling with his sense of who he really was, he leaves India for London on a scholarship to study at a University. It was a scary life for him, completely foreign to the life he was used to. Willie had to change all his habits and manners, and make himself more snobbish and pompous to fit the style of behavior at the University. He was also confounded with a new sense of freedom and used that freedom to explore himself. Willie gains confidence and a few friends like Percy Cato, who try to help him conquer his own self-doubt through sexual adventures. He often falls for the girlfriends of his friends and is often agitated and unsure of himself. Throughout this process he captures the art of writing and publishes a book, a collection of short stories he wrote. After months he finally gets a response from a fan, a woman named Ana, and falls in love with her. Ana makes him feel confident and secure as she accepts him for who he is. Willie doesn't have to hide his background or personality and with no better option after his scholarship terminates, he marries Ana and moves to the Portuguese colony in Africa where Ana's grandfather had established a mighty estate house through his wealth.

When Willie arrives there, he knows he made a mistake. This life with Ana is not for him. But he stays for 18 years. 18 long and tumultuous years. Willie learns the language there and takes his role as head of the estate. He and Ana are in love but slowly we see this love wither away. They become friends with the nearby estate owners and seem like a great couple but a rift is slowly opening up between the two of them. Willie once more tries to find himself through his friends and various sexual adventures. It started off as a one-time thing but Willie slowly begins to repeatedly visit the places of pleasure. Even this leaves him feeling haunted and empty. He tries to go to the port city nearby and find something meaningful in his life but there is noting there for him. A new couple move in near Willie and Ana's estate house and Willie falls in love with the woman who moved there, Graca. He makes love to her many times but never sees her again after the guerrilla fighters kill Graca's husband. Life is unsteady and nobody knows how everything will pan out because of the war. Willie and Ana now sleep in separate bedrooms, but they do talk. Finally, at the age of 41, Willie slips on the front steps of the estate and in the hospital, tells Ana he wants a divorce. He felt like he had done nothing in his life, and lived a life that was not his own.

In this reaction, sodium hydroxide (NaOH) disassociates into sodium (Na+) and hydroxide (OH-) ions when dissolved in water, thereby releasing OH- ions into solution. Arrhenius acids are substances which produce hydrogen ions in solution. Arrhenius bases are substances which produce hydroxide ions in solution.

The ions exist in base solutions is OH⁻ ions.

A basic solution is an aqueous solution containing more OH⁻ ions than H⁺ ions.

When NaOH as a solute is mixed into the solvent like water, it separates NaOH into Na+ and OH-. The sodium ions Na⁺ have little effect on the solution, but the hydroxyls OH⁻ ions makes the solution more basic.

Thus, NaOH form a basic solution by the presence of OH⁻ ions into it.

In an ionic compound's chemical formula, the positive ion (or cation) is written first, followed by the negative ion (or anion).

Ionic compounds are formed when positively charged ions (cations) and negatively charged ions (anions) come together due to electrostatic attraction. In the chemical formula of an ionic compound, it's customary to write the cation (positive ion) first and the anion (negative ion) second.

For example, let's take the compound "Sodium Chloride" (table salt). Sodium (Na) is the cation, which has a positive charge, and chloride (Cl) is the anion, which has a negative charge. In the chemical formula for sodium chloride, the positive ion (Na) is written first, followed by the negative ion (Cl). The formula is NaCl.

So, when presented with options A, B, C, and D, the correct choice is A, as it aligns with the convention of writing the name of the positive ion first in the chemical formula of an ionic compound.

Answer:

It will move away from the large ball because like charges repel.

Explanation:

Electric force is the force that pushes apart two like charges, or that pulls together two unlike charges. The basic law of electrostatics Like charges of electricity repel each other, whereas unlike charges attract each other. When small, positively charged ball is moved close to a large, positively charged ball it would be pushed away from the large positively charged ball since they are both positively charged. One has to put in energy to try to move the small ball closer to the large ball. The closer one try to move it to the large ball, the more energy one has to put in, so the more electrical potential energy the small ball would have.

Answer:

It will move away from the large ball because like charges repel.
