Answer:
t_{out} = t_{in}, t_{out} =
Explanation:
This in a relative velocity exercise in one dimension,
let's start with the swimmer going downstream
its speed is
The subscripts are s for the swimmer, r for the river and g for the Earth
with the velocity constant we can use the relations of uniform motion
= D /
D = v_{sg1} t_{out}
now let's analyze when the swimmer turns around and returns to the starting point
= D /
D = v_{sg 2} t_{in}
with the distance is the same we can equalize
t_{out} = t_{in}
t_{out} = t_{in}
This must be the answer since the return time is known. If you want to delete this time
t_{in}= D /
we substitute
t_{out} = \frac{v_s - v_r}{v_s+v_r} ()
t_{out} =
Answer:
The charge resides on the outer surface = C
Explanation:
Surface area of cell
Separation between two plate
Dielectric constant
Potential difference
The capacitance of parallel plate capacitor in free space is given by,
Where permittivity of free space =
The Capacitance of capacitor is increase by times when it placed in dielectric medium.
And we know that,
So charge on the outer surface is given by,
