Given water's dipole moment of 6. 17×10−30c⋅m, what's the energy change when a water molecule, with its dipole moment initially opposite a 1. 81-kn/c electric field, swings to align with the field?.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
