charge = current x time = 0.5x 20=10Coulombs
Answer:
Part a)
part b)
Part c)
Part d)
here since wave is moving in negative direction so the sign of must be positive
Explanation:
As we know that the speed of wave in string is given by
so we have
now we have
now we have
Part a)
= amplitude of wave
part b)
here we know that
so we have
Part c)
Part d)
here since wave is moving in negative direction so the sign of must be positive
