Australia's skin cancer rate is so high. The Australian Health Alliance has asked you to write a short argument that explains this to the Australian public. Remember to
explain how your evidence supports your claim to make your argument as complete and convincing as possible. You can agree with one or both of the claims.
Question: Why is Australia's skin cancer rate so high?
Claim 2: There is something different about the sunlight in Australia.
Claim 3: More people in Australia have skin that is easily damaged by sunlight.
Answer:
Claim 2
Explanation:
Australia's skin cancer rate is so high because of the climate and the weather in their area. It is also because since australia is on the bottom of the globe, the continent recieves higher UV radiation.
Thanks for the brainliest!
1.Australia has one of the highest rates of skin cancer in the world. This is due largely to our climate, the fact that many of us have fair skin that isn't really suited to such harsh conditions, our proximity to the equator (high UV levels) and our social attitudes and love for the outdoors.
2.Australia's unusually harsh sunshine results mainly from its location in the Southern Hemisphere. The elliptical orbit of the Earth places the Southern Hemisphere closer to the sun during its summer months than the Northern Hemisphere during its summer.
3.Basically, through migration, our two countries have been populated by many people with fair skin whose ancestors come from much less sunny climates. Lack of protective pigmentation leaves skin cells especially vulnerable to the DNA-damaging rays from the sun.20 Mar 2018

In the photoelectric effect, electrons are ejected by matter only if they are given energy from light of a high enough frequency. It does not matter how bright the light source is; only frequency matters. Which reasoning explains why particles are better than waves for describing this phenomenon?(1 point)
The energy from the waves of light coming from bright lights would add up and free an electron.
The energy from light waves is canceled out by interference at low energies, but not at high energies, so it can free electrons with bright light.
The energy from photons of light would never be enough to free electrons because they don't have the same energy if they are just particles.
The energy from photons of light should be enough to knock out an electron, no matter what the frequency of light is, because it is moving so fast.
Answer:Answer is A:The energy from the waves of light coming from bright lights would add up and free an electron.
Explanation:
1. They collect evidence and make sure that the model can be used with reasoning to explain the evidence.
2. The energy from the waves of light coming from bright lights would add up and free an electron.
3. The spots are the result of interference, which happens with waves but not particles.
4. This is not something that waves do because they need a medium to travel through, while particles do not.

Under what circumstances can differentiation occur in a planet?.
State Newton's law of motion.
Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Explanation:
Use the passage to answer the question.
Light can be passed through two slits and projected onto a screen. The light from the two light sources produces a pattern of dark and light spots on the screen. The spots can be the result of interference, which happens with waves but not particles. This shows that the wave explanation is best for explaining the spots.
What is the reasoning in this passage?
(1 point)

An object initially at rest on a horizontal surface is set into motion by the application of a force. Does the force of friction between the object and the surface decrease, increase, or remain the same immediately after the object starts to move?
Answer:
C always
Explanation:
The force of friction between the object and the surface decrease immediately after the object starts to move.
What is friction?The force preventing solid surfaces, fluid layers, and material components from sliding past one another is known as friction.
The definition of static friction is: The resistance people feel when they attempt to move a stationary object across a surface without actually causing any relative motion between their body and the surface they are moving the object across.
The resistance that is formed between any two items when they are sliding against one another is known as sliding friction.
It is experimentally proved that the force of friction between the object and the surface decrease, immediately after the object starts to move.

Which is an example of measurement that considers velocity? A the size of a standard basketball B the speed of baseball pitch C the placement of players on a field D the study of how records get broken
Answer: B, the speed of baseball pitch
Explanation:
The speed of a baseball pitch is an example of a measurement that considers velocity, therefore the correct answer is option B.
What is speed?The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second.
average speed = total distance /Total time
The speed of the baseball pitch is an example of the measurement of velocity.
The size of a standard basketball is an example of the measurement of length.
similarly, option C and option d are unrelated to the measurement of the velocity.

If carrots have 80j of energy how much energy will a rabbi get from eating the carrot
Answer:
8
Explanation:
According to the 10% law of energy transfer,
only about 10% of energy will be transferred to
the successive level from the previous trophic
level. Therefore according to this law carrot will
have the highest energy level as it is present at
the lowest trophic level.
Then it will transfer 10% of its consumed energy
to the rabbit and then snakes will get 10%
energy of rabbit after consuming it. Therefore if
the energy amount is given it can be calculated
by dividing it by 10 for upper trophic level.
So if a rabbit receives 80 calories of energy
from eating carrots it will pass only 8
(80/10=8) calory of energy on to a snake.
Therefore the correct answer is 8 calories
where should clouds form and why
Answer:
When air rises in the atmosphere it gets cooler and is under less pressure. When air cools, it's not able to hold all of the water vapor it once was. Air also can't hold as much water when air pressure drops. The vapor becomes small water droplets or ice crystals and a cloud is formed.

The Earth pulls on the Sun with the same magnitude force that the Sun pulls on the Earth. If these forces are equal, why does Earth go in orbit around the Sun? Why does Earth experience a great centripetal acceleration, while the Sun doesn't?
Answer:
For every force there is an equal and opposite reaction force.
For instance, if one wants to find the acceleration of a person standing on a scales, he uses the force exerted by the scales on the person,
One doesn't consider the reaction force of the person on the scales.
Likewise for the force of the sun on the earth
m v^2 / R = G M m / R^2 descibes the force acting on the earth to produce the centripetal acceleration of v^2 / R
The sun experiences the same centripetal acceleration as the earth, but since the mass of the sun is about 333,000 times the mass of the earth the acceleration can be ignored for most purposes.
When a satellite experiences an acceleration of v^2 / r, the earth is undergoing the same centripetal acceleration. However since the mass of the earth is much greater than that of a satellite and the centripetal acceleration of the earth is ignored.
An object is being acted on by a force of 20 N directed to the left and a force of 30 N directed to the right. What is the net force acting on the object
Answer:
10 newtons to the right
Explanation:
the net force is the sum of all forces.
so let's say the force acting on the left of the object is negative and the force acting to the right is positive.
so:
30 - 20 = 10 newtons.
since the force is positive we can say that the net force is 10 newtons to the right
