There are models that work with batteries and others with batteries that can be charged in the electrical network. Let's look at an average brush, with a power of 3 W. If you brush your teeth 3 times a day for 5 minutes, you have a daily consumption of 0.00075 kWh. In one month, consumption would amount to 0.225 kWh.
match each burn type with an appropriate treatment
Answer:
Burn symptoms vary depending on the severity or degree of the burn. Symptoms are often worse during the first few hours or days after the burn. Burn symptoms include:
Blisters.
Pain.
Swelling.
White or charred (black) skin.
Peeling skin.
Explanation:
How are burns managed or treated?
Burn treatment varies depending on the cause and severity. You need to keep all burns clean and apply proper bandages/dressing depending on the severity of the wounds. Treating the person’s pain is key: inadequate control can interfere with wound care.
Continue to check wounds for signs of infection and other long term issues, such as scarring and tightening of the skin over joints and muscles, which makes them difficult to move.
Treatments by burn type include:
First-degree burns: Run cool water over the burn. Don’t apply ice. For sunburns, apply aloe vera gel. For thermal burns, apply antibiotic cream and cover lightly with gauze. You can also take over-the-counter pain medication.
Second-degree burns: Treatment for second and first-degree burns is similar. Your healthcare provider may prescribe a stronger antibiotic cream that contains silver, such as silver sulfadiazine, to kill bacteria. Elevating the burned area can reduce pain and swelling.
Third-degree burns: Third-degree burns can be life-threatening and often require skin grafts. Skin grafts replace damaged tissue with healthy skin from another of uninjured part of the person’s body. The area where the skin graft is taken from generally heals on its own. If the person does not have enough skin available for graft at the time of injury, a temporary source of graft can come from a deceased donor or a human-made (artificial) source but these will eventually need to be replaced by the person’s own skin. Treatment also includes extra fluids (usually given intravenously, with an IV) to keep blood pressure steady and prevent shock and dehydration.
Third-degree burns that are deep and affect a large portion of the skin are very serious and can be life-threatening. Even first- and second-degree burns can become infected and cause discolouration and scarring. First-degree burns don’t cause scarring.
Potential complications of third-degree burns include:
Arrhythmia, or heart rhythm disturbances, is caused by an electrical burn.
Dehydration.
Disfiguring scars and contractures.
Oedema (excess fluid and swelling in tissues).
Organ failure.
Pneumonia.
Seriously low blood pressure (hypotension) may lead to shock.
Severe infection that may lead to amputation or sepsis.
You hold a 0.125 kg glider A and a 0.500 kg glider B at rest on an air track with a compressed spring of negligible mass between them. When you release the gliders, the spring pushes them apart so that they move in opposite directions. When glider A has moved 0.960 m to the left from its starting position, how far to the right from its starting position has glider B moved?
A student notices that he does better on tests if he sleeps for at least 8 hours. He decides that for the next 3 tests he has in science class, he will sleep different amounts of times and see how he does on his tests. For his next science test, he sleeps only 4 hours the night before, 6 hours before the next test, and 8 hours before the final exam. The chart shows his data. grade Test 1 2 3 Hours of Sleep 4 6 8 Grade 56 75 80 What is the dependent variable?
The dependent variable in the experiment in which a student sleeps different intervals of time to get different grades is the grade
In this experiment,
Independent variable = Hours of sleepDependent variable = GradesControl variable = The studentAn independent variable is the variable that can be altered by the researcher to get different results. The dependent variable is the variable that gets altered due to the change in independent variable.
Therefore, the dependent variable is the Grades

Describe the particles when water is a liquid. What is their distance from one another? How quickly do they move? What did equations look like?
Particles in liquids are dispersed randomly and are relatively near to one another. The particles, collisions between them happen more frequently than in gases even if particles are moving quickly in all directions.
What is meant by particle ?A particle, also known as a corpuscule in older texts, is a tiny, confined object to which one or more physical or chemical attributes, such as size, density, or mass, can be applied.
How many particles are there in physics?There are 61 subatomic particles in the Standard Model as it is currently constructed. Since the mid-1950s, hundreds of more kinds of particles have been found. These subatomic particles can mix to produce composite particles.
What are particles made of?The Standard Model of Subatomic Particles is now thought to be the best theory to explain the universe's most basic constituents. It discusses how the building blocks of all known matter are quark, which make up neutrons and protons and leptons, which contain electrons.

Diversifying the municipal water portfolio with water recycling, The desalination processUse of groundwater can reduce risk of water shortages due to droughtWhat is drought?A drought is described as a moisture deficit relative to the average water availability at a given location and season. A drought is also defined as drier than normal conditions.
Water shortage is becoming an increasing threat in Cape town because of climate change impacts which includes changing rainfall patterns and rising temperatures and increasing water demand.
In summary, the city of Cape town can develop engineering dams and 'importing' water through inter-basin transfer schemes to help in fighting drought.

A 1-column table. The first column labeled properties of mixtures has entries has no set composition, must have more than one state of matter, must have more than one substance.
What mistake did Dominic make?
The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed.
There is a definite recipe to make each mixture, so the composition of a mixture is set.
Although it is possible to have more than one state, it is also possible to have only one state.
A single substance can be used to make a mixture if the substance is composed of more than one element.
The mistake that Dominic made in the above prompt is: "Although it is possible to have more than one state in mixtures, it is also possible to have only one state." (Option C).
What is a mixture?A mixture is a material composed of two or more separate chemical components that are not chemically linked. A mixture is the physical combination of two or more substances that retain their identities and are blended in the form of solutions, suspensions, and colloids.
Mixtures are classified into two types: heterogeneous and homogeneous. Heterogeneous mixes feature distinct components, whereas homogeneous mixtures look uniform throughout. A solution, which can be solid, liquid, or gas, is the most frequent form of homogeneous combination.

A light ray travelling from diamond into air has an angle of refraction of 56. A piece of glass is then placed right next to the diamond. Explain how the angle of refraction will change now that the light is moving from diamond into glass instead of air
The angle of refraction of a light ray travelling from diamond into air has an angle of refraction of 56 will decrease now that the light is moving from diamond into glass instead of air.
When a light ray travels from rarer medium to a denser medium, the refracted ray tends to move towards the normal. So angle of refraction < angle of incidence. When a light ray travels from denser medium to a rarer medium, the refracted ray tends to move away from the normal. So angle of refraction > angle of incidence.
Glass is denser than air. So the angle of refraction will be higher for air than the angle of refraction of glass. So, when the medium is changed from air to glass, the angle of refraction will decrease.
Therefore, the angle of refraction of a light ray travelling from diamond into air has an angle of refraction of 56 will decrease now that the light is moving from diamond into glass instead of air.
