Answer:
The waves are traveling in a speed of
v=1.20 m/s
Explanation:
The fisherman see a wave at 6m apart so that's the wavelength
Now the period is the time between two successive waves so
The velocity of the waves is describe by:
Answer:
The new current in the wire is 6.3 A.
Explanation:
Given that,
Force in a straight wire, F = 0.023 N
Current in the wire, I = 2.5 A
If new force is, F' = 0.058 N, we need to find the new current.
We know that, magnetic force is given by :
It is clear that force is directly proportional to electric current. So, we can say:
I' is new current
So, the new current in the wire is 6.3 A. Hence, this is the required solution.
