Answer:

Between point E to D

Explanation:-

Please provide the attachment. I have searched this question online and got the graph. So the answer is between point E and D when graph is linear. From D to E when the curve is linear evaporation is taking place and in opposite direction condensation. Any graph should be learned in a systematic manner by paying attention towards arrow and you would get the answer yourself.

A natural water molecule (H2O) in its vapor state has an electric dipole moment of magnitude, p = 6.2 x 10-30 C.m. (a) Find the
Vika [28.1K]

Answer:

a    D = 3.9 *10^{-12} \ m

b    \tau_{max} = 1.24 *10^{-25} \  N\cdot m

c   W =  2.48 *10^{-25} J

 

Explanation:

From the question we are told that

   The magnitude of electric dipole moment is  \sigma  =  6.2 *10^{-30} \ C \cdot m

     The electric field is E =  2*10^{4} \ N/C

   

The distance between the positive and negative charge center is mathematically evaluated as

     D =  \frac{\sigma }{10 e}

Where  e is the charge on one electron which has a constant value of  e = 1.60 *10^{-19} \ C

  Substituting values

     D =  \frac{6.20 *10^{-30}}{10 * (1.60 *10^{-19})}

      D = 3.9 *10^{-12} \ m

The maximum torque is mathematically represented as

       \tau_{max} = \sigma * E  * sin (\theta)

Here  \theta  =  90^o

This because at maximum the molecule is perpendicular to the field

    substituting values

       \tau_{max} =  6.2 *10^{-30} * 2*10^{4} sin ( 90)

       \tau_{max} = 1.24 *10^{-25} \  N\cdot m

The workdone is mathematically represented as

      W =  V_{(180)} - V_{0}

where   V_{(180)} is the potential energy at 180° which is mathematically evaluated as

     V_{(180) } = -   \sigma  * E  cos (180)

Where the negative signifies that it is acting against the  field

   substituting values

     V_{(180) } = -   6.20 *10^{-30}  * 2.0 *10^{4}  cos (180)

      V_{(180) } = 1.24*10^{-25} J

and

     V_{(0)} is the potential energy at 0° which is mathematically evaluated as

            V_{(0) } = -   \sigma  * E  cos (0)

   substituting values

     V_{(0) } = -   6.20 *10^{-30}  * 2.0 *10^{4}  cos (0)

      V_{(0) } =- 1.24*10^{-25} J

So W =  1.24 *10^{-25} - [-1.24 *10^{-25}]

    W =  2.48 *10^{-25} J

Kalisha is going to cut the remaining 21 1/2 buns into thirds. How many 1/3 size buns will she have?
baherus [9]
Total buns = 21 1/2 = 43/2 buns
1/3 size buns would be: 43/2 / 1/3 = 43*3 / 2 = 129/2

In short, Your Answer would be 129/2 or 64 1/2 or 64.5

Hope this helps!

a car traveling at 11.2 m/s increases speed to 24.6 m/s over 4.4 seconds. what is the acceleration of the car
Sveta_85 [38]

Answer:

24.6 - 11.2 / 4.4 = 3.045m/s

Explanation:

acceleration = vf-vi / time

vf= 24.6 m/s

vi= 11.2 m/s

t= 4.4s

Which statement is true of a wave that’s propagating along the pavement and girders of a suspension bridge?
Readme [11.4K]
Had to look for the options and here is my answer.
The statement that is considered correct regarding a wave that is propagating along the pavement and girders of a suspension bridge is this: "t<span>he wave is mechanical, with particles vibrating in a direction that is perpendicular to that of the wave, forming compressions and rarefactions." Hope this helps.</span>
