Answer:
0.20 Hz
Explanation:
Frequency is the reciprocal of the period. The period is 5 seconds, so the frequency is 1/(5 s) = 0.20 Hz.

your answer.
b. Give an example of a way that we can control the flow of electricity in circuits
around the home.
A. the light bulb goes out once the circuit is open since it causes the flow of electricity to cut off. the light bulb dosent get the energy it needs to light up
Explanation:
B. a simple example of this in our every day life is a light switch. when you switch the light on then the circuit is closed and the energy transfers to the light bulb, when u switch the light off then you cut off the lights source of energy which causes the light to turn off.
A perfectly spherical orange is split into four equal sections. if the radius of the orange is 4 centimeters, what is the total surface area of one slice? 16π cm2 32π cm2 24π cm2 64π cm2
The total surface area of one slice will be 64 π cm².
What is the total surface area?The total surface area includes the base as well as the curving component. It is the whole area covered by the object's surface.
The total area of a form with a curved surface and base is equal to the sum of the two areas.
The total surface area of the sphere will be;
[tex]\rm A=4 \pi r^2 \\\\ \rm A=4 \times \pi (4)^2 \\\\ \rm A=64 \pi \ cm^2[/tex]

Question #3:
A sample of helium behaves as an ideal gas as it is heated at constant pressure from 293 K to 363 K. If 70 J of work is done by the gas during this process, what is the mass of the helium sample? The universal gas constant is 8.31451 J/mol · K. Answer in units of g.
For a sample of helium behaves as an ideal gas as it is heated at constant pressure from 293 K to 363 K, the mass of the helium sample is mathematically given as
n= 0.0986 g
What is the mass of the helium sample?Generally, the equation for the ideal gas is mathematically given as
PV=nRT
Therefore
W = P*(V2-V1)
W=nR(T2- T1)
n = W / (R*(T2 - T1) )
n= 4g/mol ∙ 16 J / (8.3145J/molK ∙ (351K - 273K) )
n= 0.0986 g
In conclusion, the mass of the helium sample
n= 0.0986 g

An electromagnetic wave moves through electric and magnetic fields. What is the relationship between the wave and the fields?
Answer:
the electric and magnetic fields that make up an electromagnetic wave are perpendicular (at right angles) to each other. Both fields are also perpendicular to the direction that the wave travels. Therefore, an electromagnetic wave is a transverse wave.

Answer:
In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit).

When 20. joules of work are done in 4.0 seconds; what is the power developed?
A. 0.20 watt
B. 5.0 watts
C. 16 watts
D. 80. watts
the power developed when, 20 joules of work are done in 4.0 second.
solution:power= workdone/ time
here workdone= 20 joules
time taken= 4.0s
so putting these values in the above formula, we get:
power= 20/4.0
=5.0 watts
answer= option b) 5.0 watts
[tex]\bold\blue{Formula : }[/tex]
[tex]\bold{Power = \frac{energy}{time} }[/tex]

They are artificial resources that humans use but are not able to be recycled or reused
Answer:
No. 1 is the correct answer.
Explanation:
The natural resources which deplets after long and continious use and are unable to be recreated/ takes a lot of time to renew are non renewable resources
Describe mathematically how two distinct waves each with wave functions like the one in eq. 2 – call them y1 and y2 – will combine. We call this interaction the principle of superposition.
The resultant wave of the different wave functions is = y1 + y2
Calculation of the resultant wave functionsThe principle of superposition states that two waves moving through the same medium, the resultant value of the wave function is the sum of the different wave functions.
Waves superimpose by adding their disturbances,each disturbance corresponds to a force, and all the forces add.
Therefore, the resultant wave of the different wave functions is the addition of both wave functions which is = y1 + y2.

What is the reasoning in this passage?
(1 point)
Light travels from the stars to Earth.
As light travels, it moves through the empty vacuum of space.
This shows that the particle model is best for explaining this phenomenon.
This is not something that waves do because they need a medium to travel through, while particles do not.
This is not something that waves do because they need a medium to travel through, while particles do not.
How light travels in space?A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.
So we can conclude that electromagnetic waves like light do not require medium for its propagation.

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
