Who came up with an idea of using wooden paddles?

The hand paddle was invented by Benjamin Franklin who came up with an idea of using wooden paddles attached to the hands and feet that help swimmers swim faster.

Denis Papin had suggested that the pressure and fresh air inside a diving bell could be maintained by a force pump or bellows.

Snorkel allows breathing at the surface with the face submerged. It is used as an adjunct to scuba.

Dry Valve is a valve on top of the tube that completely stops water from entering the tube when diving underwater.

Snorkelling is an activity in which a person swims using a mask, snorkel and swimming aids without using self-contained underwater breathing apparatus (SCUBA).

This time we are comparing twin sisters who are the same age and the same size. Betty drinks 6 glasses of wine in 1 hour. Barbara takes her time. She drinks her 6 glasses over 3 hours. Who will absorb the alcohol more quickly - Betty or Barbara?

Answers

Betty drinks 6 glasses of wine in 1 hour and Barbara drinks her 6 glasses over 3 hours. As alcohol is absorbed faster when there is a higher alcohol concentration. Therefore, Betty will absorb the alcohol more quickly compared to Barbara.

Alcohol absorption rate is influenced by several factors like body weight, gender, age, and food in the stomach. When comparing twin sisters, who are the same age and the same size, we have to analyze their alcohol metabolism rate.The rate of absorption of alcohol is faster when the stomach is empty and the alcohol concentration is higher. When there is food in the stomach, the alcohol is absorbed slowly.

Since Barbara is drinking 6 glasses of wine over 3 hours, it is expected that the alcohol concentration is lower compared to Betty who drinks 6 glasses in 1 hour.Betty would have a higher alcohol concentration in her bloodstream compared to Barbara, thus, would absorb the alcohol faster. This is because Betty consumed all six glasses within an hour, and she did not have food in her stomach to slow down the absorption rate.

Alcohol is absorbed faster when there is a higher alcohol concentration. Therefore, Betty will absorb the alcohol more quickly compared to Barbara. However, the long-term effects of alcohol consumption depend on other factors such as genetics, lifestyle, and other health factors.

evaluate both effectiveness and ineffectiveness of cancer association of South Africa

Answers

Answer:

The effectiveness of the Cancer Association in South Africa can be seen through the distribution of offices across the country, successfully bringing concepts of cancer prevention and treatment to many people. However, the ineffectiveness of this association can be seen by the failure to bring information to the most remote and isolated communities in the country.

Explanation:

The cancer association in South Africa is a non-governmental organization that has numerous volunteers, including doctors and other health professionals, who are committed to helping people with cancer across the country. This institution has existed for more than 70 years and has several offices spread across the country, so it is efficient in helping a large number of people in different communities. However, the association has failed to take its work to remote and more isolated communities, which are most in need of humanitarian, social and health assistance.

Cancer association of South Africa CANSA is an organization which helps fight cancer in South Africa.  It was established in 1931, to provide public service to people who are suffering from deadly disease like cancer.

Effectiveness of CANSA is that it works towards educating people regarding symptoms of cancer when it is in early stage. They also provide care and support to people who are intact with this disease.

Ineffectiveness of CANSA is that it is an active organization for almost a century but it has not been able to eliminate this disease completely from South Africa. There is no development to increase life span of people who are suffering from cancer.

Discus phototherapy and the principles that govern its practice

Answers

Answer:

Phototherapy is a medical treatment that involves the use of light to treat various skin conditions. The most common use of phototherapy is for the treatment of neonatal jaundice, where newborn infants are exposed to blue light to break down bilirubin that accumulates in the bloodstream and causes yellowing of the skin and eyes. The principles that govern the practice of phototherapy include:

1. Wavelength: Different skin conditions require different wavelengths of light. For example, blue light is used for neonatal jaundice, while UV light is used to treat skin disorders such as psoriasis and eczema.

2. Intensity: The intensity of the light used in phototherapy is crucial in determining the effectiveness of the treatment. The intensity of the light is measured in Joules per square meter (J/m²).

3. Dose: Phototherapy treatments are administered in specific doses to ensure that the right amount of light is delivered to the affected area.

4. Duration: The duration of phototherapy treatment depends on the severity of the condition being treated. For neonatal jaundice, the treatment typically lasts for several days, while treatments for skin disorders can last for several weeks or months.

5. Safety: Phototherapy can have side effects such as skin irritation and damage to the eyes. Therefore, safety measures should be taken during treatment, such as using protective goggles and monitoring the skin closely for signs of irritation or burns.

Overall, the principles of phototherapy involve careful consideration of the type of light used, the intensity and duration of the treatment, and the safety measures taken to ensure that the treatment is effective and safe for the patient.

1. Why do you think the use of hallucinogens tends to be illegal?
Need help with 1-4 ASAP!!

1. Why do you think the use of hallucinogens tends to be illegal? Need help with 1-4 ASAP!!

Answers

Answer:

#1 - Hallucinogens tend to be illegal because they can cause major damage to you and cause you to go  insane. Most hallucinogens make you hallucinate and see things that aren't there which eventually makes you panic and if you aren't in the right state of mind that can be really bad for you. Unlike most hallucinogens, marijuana doesn't make you hallucinate nor does it actually harm or affect you in a negative way and cause you to go insane which s why marijuana is legal and other hallucinogens are not.

#3 - Depressants contain things to make one consuming them more hyper/energetic and seem happier but it doesn't do anything mentally. Depressants have some of the same things as meth which is why they have the affects on the consumer like they do. Stimulants have the same as marijuana. A lot of anxiety medicine has CBD which is the part of the plant that doesn't get you high and then a lot of the medicine they give to kids with ADHD/ADD has parts of the plant as well which is why when they take these medications they tend to look like zombies.

#4 - Marijuana is used a lot for anxiety and pain and it works really well however the only thing making it a drug is being able to get high off it. You get high fro the THC in the plant not the CBD so doctors use the CBD but the THC is what helps with joint ans and stuff like that. You don't hallucinate with marijuana and it doesn't impair any major abilities like vision its only negatve affect is making you lazy

Disadvantages and advantages of a play-based approach and desk policy approach on the holistic development and optimal learning of a 3-4-year-old​

Answers

A play-based approach and a desk policy approach are two different approaches to early childhood education that have different advantages and disadvantages for the holistic development and optimal learning of 3-4-year-olds.

Advantages of a play-based approach:
- Children learn through hands-on, playful experiences that are developmentally appropriate and engaging.
- Play-based learning promotes creativity, imagination, problem-solving, and social skills.
- Children can explore and discover their own interests and passions.
- Play-based learning can be tailored to meet the individual needs and abilities of each child.

Disadvantages of a play-based approach:
- It can be difficult to assess and measure children's learning outcomes.
- Some children may struggle with self-regulation or may not be motivated to participate in play-based activities.
- Play-based learning may not prepare children for more structured, academic environments.

Advantages of a desk policy approach:
- Children learn in a more structured, academic environment that prepares them for later schooling.
- Children have opportunities to develop important literacy and numeracy skills.
- Teachers can easily assess and measure children's learning outcomes.
- Children learn important skills such as following directions, sitting still, and working independently.

Disadvantages of a desk policy approach:
- Children may not be developmentally ready for a structured, academic environment.
- Children may become disengaged or bored with repetitive, teacher-directed activities.
- Children may not have opportunities to develop important social and emotional skills.
- Children may not have opportunities to explore their own interests and passions.

In conclusion, both a play-based approach and a desk policy approach have advantages and disadvantages for the holistic development and optimal learning of 3-4-year-olds. It is important for educators to consider the individual needs and abilities of each child and to create a learning environment that is engaging, developmentally appropriate, and tailored to meet the needs of each child.
