Answer:
D) Insects would have trouble walking on the water.
Explanation:
Answer:
I =
(K+5)
Explanation:
Given :
J = k+5
Now selecting a thin ring in the wire of radius "r" and thickness dr.
Current through the thin ring is
dI = J X 2πrdr
dI = (K+5) x 2πrdr
Now integrating we get
I = 
I = (K+5) 2π
I = (K+5) 2π 
I =
(K+5)
Frequency = how many waves you get per sec
Period = how long each wave takes
Period = 1/frequency
