Answers

Answer:

4 p and 10 O on both sides

Explanation:

on the reactant side you can see easily  that there are 4 P. With the oxygen on the reactant side you take the coefficient (5) times the subscript (2) which gives a total of 10 Oxygens.

On the product side there is a subscript of 4 next to the p, and a subscript of 10 next to the O

They are equal on both sides so you are done.

Which best describes the role of the water cycle? HELPPPP ASPPPPP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Circulates existing water on Earth.

The water cycle, also known as the hydrological cycle, refers to the continuous movement of water on, above, and below the Earth's surface. It involves processes such as evaporation,

condensation, precipitation, and runoff. The water cycle is responsible for circulating existing water on Earth, redistributing it from one place to another, and maintaining a constant supply of water in different forms (liquid, vapor, and ice) across various reservoirs like oceans, lakes, rivers, and the atmosphere. It plays a crucial role in balancing the Earth's water resources and supporting life on our planet.

Therefore the role of water cycle is best described by

Use the following scenario to answer the question.

Pete hangs a weight from a spring and then releases it. He watches as the spring oscillates back and forth. Pete says that this will repeat forever.

Which of the following states if Pete is right or wrong and explains the reasoning correctly?

( help please! )

A. Pete is correct because simple harmonic motion is occurring, and this type of motion should continue on forever.


B. Pete is not correct because friction will cause the spring to fall and rise with a shorter distance during each oscillation. The spring will eventually come to rest entirely.


C. Pete is not correct because eventually the weight will fall off the spring, causing the motion to cease.


D. Pete is correct because friction will cause the spring to fall and rise with a greater distance during each oscillation. It will never stop completely.

Answers

Answer:

Option: B

Explanation:

The correct answer is B. Pete is not correct because friction will cause the spring to fall and rise with a shorter distance during each oscillation. The spring will eventually come to rest entirely.

The motion of the spring is affected by friction, which gradually dissipates its energy. As a result, the amplitude of the oscillations decreases over time until the spring eventually comes to a stop. This phenomenon is known as damping, and it causes the motion to cease rather than continue indefinitely.[tex][/tex]

Jenna notices that the speed of the wind has increased throughout the day. What is causing the faster wind?

There has been no precipitation.
The difference in air pressure has decreased.
The difference in air pressure has increased.
The direction of the wind has changed to the south.

Answers

The speed of the wind has increased throughout the day as there has been no precipitation.

What is precipitation?

Precipitation is a process in which vapor of liquid changes into small droplets.

In the day time temperature of the atmosphere is high as compare to the night, so rate of precipitation is low at the day time due to which speed of the wind has increased as compare to the night time.

Hence, option (a) is correct i.e. there is no precipitation.

You want to push a table 5 feet across the floor. How would a decrease in the resistance caused by friction change the amount of force needed to move an object?
Write in only 1-2 sentences.

help please!

Answers

Answer: A decrease in friction will allow you to move the table with less force as friction would waste some the energy provided.

Answer: By reducing the friction, either by using lubricants, reducing the roughness of the surfaces, or other means, the resistance to motion is decreased.

Explanation:

A decrease in the resistance caused by friction would make it easier to move an object, which means less force would be needed to push the table across the floor. Friction is a force that opposes the motion between two surfaces in contact, and it can make it harder to move objects. By reducing the friction, either by using lubricants, reducing the roughness of the surfaces, or other means, the resistance to motion is decreased.

According to Newton's laws of motion, the force required to move an object is directly proportional to the resistance caused by friction. Therefore, when the resistance decreases, the force needed to move the object decreases as well. With less friction, it would be easier to overcome the resistance and push the table across the floor, requiring less force to achieve the desired movement.

Why do tides have a regular cycle of 12 hours even though the Moon completes one revolution of the Earth every 29.5 days?

(HELP PLEASE!!)

A. The Earth is rotating and completes a rotation every 24 hours. As it rotates, its distance from the Moon changes every 12 hours. This causes the cycle of high and low tide.


B. The Earth is rotating and completes a rotation every 24 hours. The moon also rotates as it resolves around Earth, which causes the cycle of high and low tide.


C. The Earth is rotating and completes a rotation every 24 hours. This means that the side of the Earth far from the Moon will be near the Moon 12 hours later, restarting the cycle of high and low tide.


D. The Earth is rotating and completes a rotation every 24 hours. This causes day and night to occur. High tide only occurs during the evening, and low tide only occurs during the day.

Answers

Answer:

D

Explanation:

The Earth is rotating and completes a rotation every 24 hours. This causes day and night to occur. High tide only occurs during the evening, and low tide only occurs during the day.

A. The Earth is rotating and completes a rotation every 24 hours. As it rotates, its distance from the Moon changes every 12 hours. This causes the cycle of high and low tide.

The regular cycle of tides is primarily caused by the gravitational interaction between the Earth and the Moon. As the Earth rotates on its axis every 24 hours, different parts of the Earth's surface come into closer proximity to the Moon. This changing distance between the Earth and the Moon results in the cycle of high and low tides occurring approximately every 12 hours.

The gravitational force exerted by the Moon on the Earth's oceans causes a tidal bulge to form on the side of the Earth closest to the Moon, resulting in high tide. Simultaneously, there is another high tide on the side of the Earth opposite the Moon due to the centrifugal force generated by the Earth-Moon system. These tidal bulges create the cycle of high and low tides as the Earth rotates.

It's important to note that while the Moon completes one revolution around the Earth every 29.5 days, the regular cycle of tides is primarily influenced by the Earth's rotation and the changing distance between the Earth and the Moon every 12 hours.

Which water crisis is the most critical to resolve?

Answers

Option (A) Circulates existing water on Earth

Final answer:

The most critical water crisis to resolve is water scarcity, which affects approximately 2.2 billion people worldwide.

Explanation:

Water crises are a pressing global issue, and identifying the most critical one to resolve requires considering various factors. While all water crises are significant, water scarcity stands out as one of the most critical challenges to address.

Water scarcity occurs when the demand for water exceeds the available supply, leading to water stress and shortages. Approximately 2.2 billion people worldwide lack access to safe drinking water, and this number is expected to increase due to population growth, climate change, and inefficient water management.

Resolving water scarcity requires a multi-faceted approach. It involves implementing sustainable water management practices, such as water conservation, rainwater harvesting, and efficient irrigation techniques. Additionally, investing in infrastructure development, such as building reservoirs and improving water distribution systems, can help alleviate water scarcity.

By addressing water scarcity, we can improve access to safe and clean water, enhance food security, and promote sustainable development. It is crucial for governments, organizations, and individuals to prioritize resolving water scarcity to ensure a better future for all.

Can someone help to summarize this document pleasesss!!! Im soooo confused Source: Henry Byroade, Assistant Secretary of State in the United States State Department, memorandum to his superior regarding British proposals concerning the overthrow of the government of Muhammad Mosaddegh, the nationalist prime minister of Iran, November 26, 1952. In August of 1953, Mosaddegh was overthrown in a coup organized by the CIA and the British intelligence agency MI6.The British Foreign Office has informed us that it is inclined to bring about a coup d'etat in Iran, replacing the Mosaddegh government by one that would be more reliable," if the United States government agreed to cooperate. You will recall the British embassy on October 8 gave us a paper that outlined the possible ways of meeting the threat that would be posed if the communist party of Iran (which is supported by the Soviet Union) took advantage of Mosaddegh's weakness to seize power. Since then, the State Department and CIA have had three meetings with British representatives. The British believe that there is virtually no chance of an oil settlement* with Mosaddegh and they have little hope that his government will be able to prevent a communist takeover. The British do not appear to have a specific candidate in mind as the leader of the suggested coup, but they believe that several of the "old guard" politicians and more moderate nationalist leaders would be good candidates.CIA believes that the project is probably feasible and that it could be handled in a way that British and American connection with it could never be proven. However, many things could go wrong. Furthermore, it must be assumed that the Iranians would charge the British with complicity in any sudden political development of this sort, with or without proof, and that this charge would be echoed by the Soviet bloc. There is also the danger of possible violent Soviet reaction, especially if the coup was not completely successful from the beginning.
