The eagle gained 882 J of gravitational potential energy.
Answer: B) Zinc will act as Anode
Explanation:
Standard reduction potential of zinc and nickel are:
Here Zinc undergoes oxidation by loss of electrons, thus act as anode as it has more negative reduction potential.
Nickel undergoes reduction by gain of electrons and thus act as cathode. as it has less negative reduction potential.
Where both
are standard reduction potentials.
As the emf is positive, the reaction is spontaneous and reaction will occur.
Thus Zinc will act as anode.
I believe it is
B)The Sun is closer than Deneb
In up milling the cutter rotates clockwise when cutting the workpiece from right to left. in down milling the cutter rotates clockwise when cutting the workpiece from left to right
The equivalent resistance of n resistors connected in parallel is given by

(1)
In our problem, the resulting resistance of the 5 pieces connected in parallel is

, and since the 5 pieces are identical, their resistance R is identical, so we can rewrite (1) as

From which we find

.
So, each piece of wire has a resistance of

. Before the wire was cut, the five pieces were connected as they were in series. The equivalent resistance of a series of n resistors is given by

So if we apply it at our case, we have

therefore, the resistance of the original wire was

.
