(In order of the given bullet points)
Five qualities of a sound wave may be used to define it: wavelength, amplitude, time period, frequency, and velocity or speed. The wavelength of a sound wave is the shortest distance at which it repeats itself.The ear canal is a tiny opening that connects to the eardrum. The eardrum is reached by sound waves passing via the ear canal, a small opening. Sound waves are "caught" by the outer ear (pinna) and sent to the middle ear, which is shielded, through the ear canal. The eardrum vibrates as a result of these entering sound waves.The majority of psychologists concur that the location principle applies to hearing sound stimuli at high frequencies, whereas those at low frequencies are explained by the frequency theory. Mid-frequency sound stimuli are thought to be properly accounted for by both hearing theories.In humans and many other species, the auditory cortex is the area of the temporal lobe that deals with auditory information. It is a component of the auditory system that performs both fundamental and advanced hearing processes, including those that may be related to language switching.

Which conclusion can be made, based on an analysis of the chart?
-> Families that only have children between six and 17 years old are more likely to move to a different state than any other group.
-> Families with no children have the highest rate of international migration.
-> Migration within the same country occurs less frequently than migration to a different country for all groups.
-> Families with children under six years old and between six and 17 years old are more likely to move to another state than to a new region.
-> Families with children under six years old are less likely to migrate than any other group.
The conclusion that can be made, based on an analysis of the data is that Families with no children have the highest rate of international migration.
What is migration?
Migration is known to be commonly defined as the movement of people and their resources from one place to the other. It can be local or international.
Note that data on US geological mobility state that Young adults are people who often move the most.
The highest rates of movers are seen in people that are said to be in their twenties. And studies has shown that one-third of the people between 20 - 29 year old's often moved like twice a year.
Hence, The conclusion that can be made, based on an analysis of the data is that Families with no children have the highest rate of international migration.

a 100 square mile area of national forest is how many acres ? how many hectares?
Based on the calculations, the area of national forest is equal to 64,000 acres and 25,600 hectares respectively.
How to calculate the area of a square?Mathematically, the area of a square can be calculated by using this formula;
A = x²
Where:
A is the area of a square.x is the side length of a square.What is measurement?Measurement refers to a process through which the dimensions, size (weight), or other physical quantities of magnitude that are associated with an object or land is taken, especially for use in a scientific research and experiment such as direct comparison.
How to convert the units?1 square mile = 640 acres
100 square mile = X acres
Cross-multiplying, we have:
X acres = 640 × 100
X acres = 64,000 acres.
For the area in hectares, we have:
1 hectare = 2.5 acres
X hectare = 64,000 acres
Cross-multiplying, we have:
2.5X acres = 64,000 acres
X = 64,000/2.5
X = 25,600 hectares.

Describe how the process of hearing works. Include the following topics.
• The characteristics of sound
• The overall function of the outer, middle, and inner ear
• Place theory and frequency theory
• The auditory cortex
The mechanism or process of hearing works first and foremost when sound waves enter the outer ear and travel through a narrow passageway which is known as the ear canal
The sound then moves from the ear canal to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. What is the auditory cortex?The auditory cortex refers to a region of sensory area of the temporal lobe which is concerned with the organ of hearing

Describe and explain, how and why, the Great Durban Metro (eThekwini) failed to adequately manage
storm and runoff water. Focus specifically on the April 2022 floods and its aftermath.
Answer:
Severe flooding and landslides caused by heavy rainfall on 11-13 April caused the death of 448 people, displaced over 40,000 people and completely destroyed over 12,000 houses in the south-east part of South Africa. It also severely damaged infrastructures: roads, health centres, schools. On 18 April, the President of South Africa declared a national state of disaster due to floods severity. On 20 April, DG ECHO field mission reported massive unattended or inadequately addressed needs notably in the most remote and isolated severely affected areas. The most urgent needs are food, clean water and hygiene packs; health, care and psychological first aid (PFA); protection and education in emergencies.
The KwaZulu-Natal Provincial Government is planning to set up 4 396 temporary accommodation sites as from the end of this week to accommodate families that are currently accommodated in community halls, churches and schools. Giving the latest update on the response to the floods in the province on Sunday, KwaZulu-Natal Premier, Sihle Zikalala, said the construction of temporary residential units has started at Ilembe District, Ugu and eThekwini. Zikalala said the provincial government is finalising the assessment of some sites in Durban in terms of their suitability for construction. “We are encouraged by the support we are getting from the national government. An integrated approach involving three spheres of government is assisting to ensure speed and efficiency in the interventions,” Zikalala said. Zikalala said that although government has reprioritised R1 billion towards disaster relief interventions, the province needs more than R1.9 billion to complete the work.
Since the original floods rains have continued and part of KwaZulu-Natal continue to be struck by devastating flooding with reports of more people being evacuated to safe areas and more roads and houses have been flooded. On 23 May, an orange level warning has been issued for disruptive rain, floodings and mudslides over the extreme north-eastern parts of KwaZulu-Natal. Six weeks later and thousands remain in evacuation shelters with an uncertain future. It's a long journey ahead for many people who have lost family member, their homes or livelihoods. As the true picture of the devastation caused by the floods emerges, many still need all help. On rebuilding homes for families, the government is working to identifying suitable land to house new settlements for the displaced. But in the meantime, thousands of people have been left homeless and are living in shelters across the province.
