Answer:
Potential energy is stored energy and the energy of position––gravitational energy. There are several forms of potential energy. Electrical Energy is the movement of electrical charges. Everything is made of tiny particles called atoms.
More compressed. moving up = apparent weight (i.e., your norma force) is greater. this means you’ll weighr more and push those springs down even more than you would at rest.
B) atmosphere pressure, i believe
Complete Question
A voltaic cell is constructed with two 
electrodes. The two cell compartment have ![[Zn^{2+}] = 1.6 \ M](https://tex.z-dn.net/?f=%5BZn%5E%7B2%2B%7D%5D%20%3D%20%201.6%20%5C%20M)
and ![[Zn^{2+}] = 2.00*10^{-2} \ M](https://tex.z-dn.net/?f=%5BZn%5E%7B2%2B%7D%5D%20%3D%20%202.00%2A10%5E%7B-2%7D%20%5C%20%20M)
respectively.
What is the cell emf for the concentrations given? Express your answer using two significant figures
Answer:
The value is 
Explanation:
Generally from the question we are told that
The concentration of ![[Zn^{2+}]](https://tex.z-dn.net/?f=%5BZn%5E%7B2%2B%7D%5D)
at the cathode is ![[Zn^{2+}]_a = 1.6 \ M](https://tex.z-dn.net/?f=%5BZn%5E%7B2%2B%7D%5D_a%20%3D%20%201.6%20%5C%20M)
The concentration of at the anode is ![[Zn^{2+}]_c = 2.00*10^{-2} \ M](https://tex.z-dn.net/?f=%5BZn%5E%7B2%2B%7D%5D_c%20%3D%20%202.00%2A10%5E%7B-2%7D%20%5C%20%20M)
Generally the the cell emf for the concentration is mathematically represented as
![E = E^o - \frac{0.0591}{2} log\frac{[Zn^{2+}]a}{ [Zn^{2+}]c}](https://tex.z-dn.net/?f=E%20%3D%20%20E%5Eo%20-%20%5Cfrac%7B0.0591%7D%7B2%7D%20log%5Cfrac%7B%5BZn%5E%7B2%2B%7D%5Da%7D%7B%20%5BZn%5E%7B2%2B%7D%5Dc%7D)
Generally the 
is the standard emf of a cell, the value is 0 V
So
![E = 0 - \frac{0.0591}{2} * log[\frac{ 2.00*10^{-2}}{1.6} ]](https://tex.z-dn.net/?f=E%20%3D%20%200%20%20-%20%20%5Cfrac%7B0.0591%7D%7B2%7D%20%20%2A%20log%5B%5Cfrac%7B%202.00%2A10%5E%7B-2%7D%7D%7B1.6%7D%20%5D)

Answer:
Moving the magnet away from the center of the loop with its south pole facing the center of the loop.
Explanation:
Electromagnetic induction is due to a rapidly changing magnetic field, or loop area. The poles of the magnet induce current in the loop but in the opposite direction, depending on the direction of their relative motion. An approaching north pole will induce an anticlockwise current in the loop, while an approaching south pole will do the reverse. To get the galvanometer to flicker in the same direction as of that when the north pole was approaching, we move the magnet away from the center of the loop with its south pole facing the center of the loop.
