Which Water Crisis Is The Most Critical To Resolve?

Answers

Answer 1

Option (A) Circulates existing water on Earth

Answer 2
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.

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]

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.
