backward movement
because momentum = mass × speed
And mass must be in positive value..
so negative value is speed
which moving backward..
I disagree that folk dance forms can be outside their original meaningful form in this scenario.

Answer:
When the electrical current passes through the conductors, the polarity is changed, and the diaphragm interacts with the permanent magnets, vibrating and creating sound.
Explanation:
Answer:
The right solution is "84.09 nm".
Explanation:
The given values are:
Refractive index of glass,
= 1.52
Refractive index of oil (n),
= 1.64
Wavelength (λ),
= 555 nm
Now,
The thickness of the film (t) will be:
= 
= 
= 
= 
Since we are working in one dimension (left right or East West), we don't need to worry about angles! It's just simply a matter of adding things up!
First list out all the forces and add negative (-ive) signs to each of the 'west' forces like this.
20 East + (-27 West) + ? = 10 East
so it's easy to see that 20 + (-27) = -7
So to get to 10 from -7 just do the sum to get 17.
Since 17 is not negative it must be in the direction of East.
So the answer is:
Magnitude = 17 N
Direction = toward the East
