Answer: when the dipole moment and electric field are parallel
Explanation: The formulae that relates the potential energy of a dipole, dipole moment and strength of electric field is given as
u = p * E cosθ
Where, u= dipole potential energy, p = dipole moment, E = strength of electric field.
The expression is at maximum when θ = 0 (cos 0° = 1)
Hence the function for potential energy will be greatest when θ = 0° which implies that the dipole moment and strength of electric field are parallel to each other.
The key principle is that crank length, just like frame size, should be proportional to the rider height and then modified to what fits the individual. There are 4 charts, two for the upright position and two for the aero position, depending upon how you race.
I believe it’s a liquid inside a beaker on a hot Bunsen burner (c)
This is because : Everyday Examples of Convection
Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion. Radiator - Puts warm air out at the top and draws in cooler air at the bottom.
Not sure if it’s right tho!
I do believe that the answer is D.
Hope this is right! Have a great day! :-)
