Question attached i need answers quick

Answer:

Ok, first, what is trash?

Trash can be different things, like organic stuff (remains of fruit or wood) or not-organic (like plastic)

Naturally, those things come from Earth, meaning that that:

The fruit is on Earth.

Someone eats the fruit

the rest is trowed in the trash

the trash is returned to some location on the Earth.

So the mass of the fruit is always in the Earth, this means that the mass of the Earth does not change by this process.

Now in the process of materials breaking down, those materials are being "absorbed" by the land, so the mass remains on the planet, this process also does not change the mass of the Earth.

D.) The mass of the Earth remains the same regardless of the amount of trash in the landfill.

Answer:

G

Explanation

The acceleration of gravity is constant, and = 9.8 m/s² , no matter what mass of the object is. Initial speed for both objects = 0 m/s. So, after 2 sec the objects will have the same speed and the same distance.

Answer G: speed=v, distance =d.

* for more than 10¹⁹ Hz cosmic rays

Explanation:

The electromagnetic spectrum is formed by transverse waves that are the oscillations of electric and magnetic fields

             c = λ f

in general this spectrum is divided into range depending on the uses of the waves

from lower frequency to higher we have

* long wave with a frequency of nos 10⁶ Hz, corresponds to radio waves

Explanation:

The orbital radius of the Earth is [tex]r_1=1.496\times 10^{11}\ m[/tex]

The orbital radius of the Mercury is [tex]r_2=5.79 \times 10^{10}\ m[/tex]

The orbital radius of the Pluto is [tex]r_3=5.91 \times 10^{12}\ m[/tex]

We need to find the time required for light to travel from the Sun to each of the  three planets.

(a) For Sun -Earth,

Kepler's third law :

[tex]T_1^2=\dfrac{4\pi ^2}{GM}r_1^3[/tex]

M is mass of sun, [tex]M=1.989\times 10^{30}\ kg[/tex]

So,

[tex]T_1^2=\dfrac{4\pi ^2}{6.67\times 10^{-11}\times 1.989\times 10^{30}}\times 1.496\times 10^{11}\\\\T_1=\sqrt{\dfrac{4\pi^{2}}{6.67\times10^{-11}\times1.989\times10^{30}}\times1.496\times10^{11}}\\\\T_1=2\times 10^{-4}\ s[/tex]

(b) For Sun -Mercury,

[tex]T_2^2=\dfrac{4\pi ^2}{6.67\times 10^{-11}\times 1.989\times 10^{30}}\times 5.79 \times 10^{10}\ m\\\\T_2=\sqrt{\dfrac{4\pi^{2}}{6.67\times10^{-11}\times1.989\times10^{30}}\times 5.79 \times 10^{10}}\ m\\\\T_2=1.31\times 10^{-4}\ s[/tex]

(c) For Sun-Pluto,

[tex]T_3^2=\dfrac{4\pi ^2}{6.67\times 10^{-11}\times 1.989\times 10^{30}}\times 5.91 \times 10^{12}\\\\T_3=\sqrt{\dfrac{4\pi^{2}}{6.67\times10^{-11}\times1.989\times10^{30}}\times 5.91 \times 10^{12}}\\\\T_3=1.32\times 10^{-3}\ s[/tex]

Answer:

Visible light

Explanation:

Answer:

C visible light

Explanation:

Answer:

It lasted two hours or 120 minutes, it would be smart to say that he was riding up it during the interval 20-60min and riding down it during the interval 60-80min. This is an assumption made because of his speed, when going up a hill our speed is slower while when riding down it, you gain a lot of speed.

Answer:

7.series

Explanation:

in parallel is like if one bulb stops work all the others will stop too

in series it remains constant or it wont change throughout a series circuit

Answer:

the answet is the 3 layer of the sun

Explanation:

isaw a solar eclipse and leanerd is

Answer:

Chromosphere

Explanation:

It is the second of the three main layers in the Sun's atmosphere and is roughly 3,000 to 5,000 kilmoeters deep.It's rosy red color is only apparent during eclipses.The chromosphere sits just above the photosphere and below the solar transtion region.

Answer:

A force is a push or pull that acts upon an object as a result of that objects interactions

Explanation:

Answer:

Short time large force

Answer:

I think maybe D

Explanation:

A is wrong, it has to be reversed

B is wrong cause they connect at the poles

C is wrong cause they always point north (that's how compases work)

D is the only one that could be possible

Hope this helped! :D

Answer:

A 1049.75

Explanation:

notice that a Nms is equal to a kg(m^2)/s which is what you get if multiply all three given values.

the formula is angular momentum = (mass)(velo)(radius)

therefore

65(3.8)(4.25) = the answer

= 1049.75

Answer:

1. 100N 2. 50N 3. 50N

Explanation:

The spring scale reading that shows how much force she must exert is 1. 100N 2. 50N 3. 50N.

A simple and affordable way to determine mass is by using spring balances. The mass is suspended from the end of the spring, and the spring's deflection as a result of the mass's downward gravitational pull is measured in relation to a scale.

The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains."

One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.

Therefore, her required force is indicated by the spring scale readings of 1. 100N, 2. 50N, and 3. 50N.

Answer: Option B.

Explanation:

In the major chord, the tonic is the "rest" note, this is the root of the chord, for example, in E major, E is the tonic.

Dominant is the note with more "strength" in the chord, is the fifth degree in the chord, for example in the C major chord, the dominant will be G.

Then the correct option is B, platonic.
