Nuclear Energy is : Energy released by reactions within atomic nuclei , as in Nuclear Fission and Nuclear Fusion

My reason being is because this is the outcome of some radio active plants when they release "gas" or chemicals into the air.

I hope this helps.

Who could explain the phenomenom of interference of light?​
Likurg_2 [28]

Answer:

When the waves reflected from the inner and outer surface combine they will interfere with each other, removing or reinforcing some parts of white light by destructive or constructive interference. ... This results in color.

Explanation:

this is what we studied

so basically  there is like a surface

and 2 different waves coming out of the same source

they will combine and start removing parts of the white light (which originally consists of 6 to 7 colors)

results in showing these colors

A) A real object 4.0 cm high stands 30.0 cm in front of a converging lens of focal length 23 cm. Find the image distance, the im
vfiekz [6]

Explanation:

Given that,

Height of object = 4.0 cm

Distance of the object u= -30.0 cm

Focal length = 23 cm

We need to calculate the image distance

Using lens's formula

\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}

Where, u = object distance

v = image distance

f = focal length

Put the value into the formula

\dfrac{1}{v}-\dfrac{1}{-30}=\dfrac{1}{23}

\dfrac{1}{v}=\dfrac{1}{23}-\dfrac{1}{30}

\dfrac{1}{v}=\dfrac{7}{690}

v=98.57\ cm

We need to calculate the height of the image

Using formula of height

\dfrac{h'}{h}=\dfrac{-v}{u}

Where, h' = height of image

h = height of object

\dfrac{h'}{4}=\dfrac{-98.57}{-30}

h'=\dfrac{98.57\times4}{30}

h'=13.14\ cm

The image is real and inverted.

(b). Now, object distance u = 13.0 cm

We need to calculate the image distance

Using lens's formula

\dfrac{1}{v}-\dfrac{1}{u}=\dfrac{1}{f}

Put the value into the formula

\dfrac{1}{v}=\dfrac{1}{23}-\dfrac{1}{13.0}

\dfrac{1}{v}=-\dfrac{10}{299}

v=-29.9\ cm

We need to calculate the height of the image

\dfrac{h'}{4}=\dfrac{-(-29.9)}{-13.0}

h=-\dfrac{29.9\times4}{13.0}

h=-9.2\ cm

The image is virtual and erect.

Hence, This is required solution.

A student needs to conduct a reaction that combines chemicals A and B to synthesize product AB . If we write this as a chemical
rusak2 [61]

Answer : The number of molecules of A needed to make 5000 molecules of AB will be, 5000

Explanation :

Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

The given balanced chemical reaction is,

A+B\rightarrow AB

As per question, molecule B is an excess reagent because it had enough molecule to make 5000 molecules of AB. So, molecule A is limiting reagent.

From the balanced reaction, we conclude that

As, 1 molecule of AB produced from 1 molecule of A

So, 5000 molecule of AB produced from 5000 molecule of A

Hence, the number of molecules of A needed to make 5000 molecules of AB will be, 5000

What the motion of an object that has an acceleration of 0 m/s
Degger [83]
<span>Everything in the system is stable and therefore the objects motion is stable. That is to say it is not changing what it is already doing. As far as i know zero times zero is still zero. In that case then the motion must be constant or stable.</span>
