Answer:
lamda=10.5m
Explanation:
using the equation of progressive wave.
y=Asin(wt-kx)
comparing the two equations together, we have
kx=0.6x , k=0.6
k=2π/λ
0.6=2*3.142/λ
cross multiply
0.6λ=6.284
divide both sides by 0.6
λ=6.284/0.6
λ=10.47m
approximate
λ=10.5m
Answer: 
Explanation:
Given
CD has a playing time of 
Initial angular speed of CD is 
Final angular speed of DC is 
Angular speed, when rpm is given


Final speed

Using equation of angular motion

Insert the values

Magnitude of angular acceleration is 
K= fx => f = k/x => 50N/100cm / 10 cm = 5/10= 0.5 N
Answer:
The neutral wire is often confused with ground wire, but in reality, they serve two distinct purposes. Neutral wires carry currents back to power source to better control and regulate voltage. Its overall purpose is to serve as a path to return energy.
