Answer:

Explanation:

The total degree of the circle = 360°

It is divided into 3 equal parts, so each part becomes 360 / 3 = 120°

conversion of 120 degree into radian you get 2pie/3 radians.

Hope this helps

Answer:

A circular pizza has a angle of 360 degrees. When you cut it into 3 equal pieces you divide 360 by 3,you get 120 degrees. And following the conversion of 120 degree into radian you get 2pie/3 radians.

ElenaW [278]

Answer:

λ  = 65.6 pm

Explanation:

Given that

λo = 65 pm

The initial energy of the electron

E_o=\dfrac{hC}{\lambda_0 }

Now by putting the values

E_o=\dfrac{hC}{\lambda_0 }

E_o=\dfrac{6.67\times 10^{-34}\times 3\times 10^8}{65\times 10^{-12}}

E_o=3.05\times 10^{-15}\ J

E_o=\dfrac{3.05\times 10^{-15}}{1.6\times 10^{-19}\times 10^3}\ KeV

Eo=19.06 KeV

Given that kinetic energy KE= 0.84 KeV

Therefore the final energy

E= Eo - KE

E = 19.06 - 0.84 KeV

E= 18.22 KeV

The wavelength  λ can be find as

E=\dfrac{hC}{\lambda}

\lambda=\dfrac{hC}{E}

\lambda=\dfrac{6.67\times 10^{-34}\times 3\times 10^8}{19.06 \times 10^3\times 1.6\times 10^{-19}}

λ = 6.56 x 10⁻¹¹ m

λ  = 65.6 pm

Which unit of measurement is most appropriate for measuring the length of your computer screen?
Alika [10]

Answer:

Inches or Centimeters

Explanation:

Inches or centimeters are the most appropriate units of measurement for the computer screen because they are in the form of whole figures that can be easily comprehended. Usually the width of computer screens span from 10 to 20 inches.

Conversion of a 15inches computer to meters;

1inch=0.0254meter

15inches= ?

15inches*0.0254/1

=0.381meters

The above is a very small figure which might be hard for most people to fathom or visualize.

Answer:

20.5

Explanation:

in this case, the two vectors are in the same direction, so they simply add:

total motion = 18m/s + 2.5m/s = 20.5m/s to the west
