Highest point ( A ) ...

Not moving ==> zero kinetic energy
Highest altitude ==> maximum potential energy
------------------------------------
Total energy ==> all potential

Halfway up, halfway down ( B ) ...

Half-altitude ==> half of total energy is potential
Moving ==> some kinetic energy; must be half of total
-----------------------------------------
Total energy ==> same total; half potential, half kinetic

Lowest point ( C ) ...

Minimum altitude ==> zero potential energy
Fastest speed ==> maximum kinetic energy
-----------------------------------------
Total energy ==> same total; no potential, all kinetic

The total energy at A, B and C is constant and does not change.

At A, all the energy is potential energy. It gets converted partially to kinetic energy at B and is completely converted to kinetic energy at C. At C, all the energy is kinetic energy.

Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in p

irina1246 [14]

Answer:

1 ohm

Explanation:

since there are two identical resistors, one resistor will be

R = $\frac{4}{2}$ =2ohm [ proven as in series $R_{e} = 2 + 2 = 4ohm$ ]

to calculate the equivalent resistance when in parallel:

$\frac{1}{R_{e} } = \frac{1}{R_{1} } + \frac{1}{R_{2}}$

so,

$\frac{1}{R_{e} } = \frac{1}{2} + \frac{1}{2}$

$R_{e} = 1ohm$

Contrast elastic potential energy and chemical potential energy

tatuchka [14]

Chemical Potential Energy is released when chemical bonds between atoms are broken (like covalent and ionic) and is released mainly as thermal
<span>Elastic Potential is released when the molecules in the material are allowed to go back to there original form, and is released mainly as kinetic</span>
