are related to each other.
3. If the frequency, increases what happens to the wavelength?

Answer:  With Hydroelectric power water is artificially stored in a high place, so it can be released and flow to a low place and through a generator. With Tidal energy the movement of water is also used to power a generator, but the flow of water is caused by the changing tides.

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

the power developed when, 20 joules of work are done in 4.0 second.

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]

[tex]\bold\blue{Given : }[/tex]

[tex]\bold\blue{ Solution : }[/tex]

[tex]\bold{Power = \frac{energy}{time} }[/tex]

[tex]\bold{Power = \frac{20}{4.0} }[/tex]

[tex] \bold{ Power = 5.0}[/tex]

So , B.) 5.0 watts is answer .

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.

This is not something that waves do because they need a medium to travel through, while particles do not.

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.

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

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

As paper remains in neutral hence it attracts the paper

Hence option B is correct

The resultant wave of the different wave functions is = y1 + y2

The 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.

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

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).

The total surface area of one slice will be 64 π cm².

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;
