Why is the sky blue?
Levart [38]

Answer:

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

An electron starts from rest in a vacuum, in a region of strong electric field. The electron moves through a potential differenc
Semenov [28]

Answer:

The kinetic energy is  KE  = 5.67*10^{-18} \ J

Explanation:

From the question we are told that

    The potential difference is  \Delta V  =  36 \ volts

       

The potential energy of the end  is mathematically represented as

        PEs  =  - q *  \Delta V

q  is the charge on an electron with a constant value of q =  1.60 *10^{-19} \  C

       substituting values

      PE  =  - 1.60*10^{-19} *  36

      PE  =  -  5.67*10^{- 18} \ J

Now from the law of energy conservation

     The PE_e    =  KEe

Where  KE _e is the potential  energy at the end

 So  

        KE  = 5.67*10^{-18} \ J

The  negative sign is not includes because kinetic energy can not be negative

An electron is traveling with initial kinetic energy K in a uniform electric field. The electron comes to rest momentarily after
KatRina [158]

Answer:

E = kQs/r.r

Explanation:

Where E is the magnitude of electric field...

k is called Columb's Constant. It has a value of 8.99 x 109 N m2/C2.

Qs is the magnitude of the source charge...

and r is the magnitude of distance between source and target...

(When electron comes to rest Δt the magnitude of Electric field E become zero momentarily but later achieves the maximum value...)
