Answer:
The electrons are moving through the superconductor per second.
Explanation:
Given :
Current A
Charge of electron C
Time sec
From the formula of current,
Current is the number of charges flowing per unit time.
Where number of charges means in our case number of electrons
Therefore, electrons are moving through the superconductor per second.
First we need to find the speed of the dolphin sound wave in the water. We can use the following relationship between frequency and wavelength of a wave:
where
v is the wave speed
its wavelength
f its frequency
Using
and 
, we get
We know that the dolphin sound wave takes t=0.42 s to travel to the tuna and back to the dolphin. If we call L the distance between the tuna and the dolphin, the sound wave covers a distance of S=2 L in a time t=0.42 s, so we can write the basic relationship between space, time and velocity for a uniform motion as:
and since we know both v and t, we can find the distance L between the dolphin and the tuna:
where
v is the wave speed
f its frequency
