Answer:
The capacite is C=5.32 uF using the equations of voltage and energy in capacitance
Explanation:
The energy holds is 5 J and the resistor dissipates 2J so the energy total is 3J
Using:
![V_{t}= V_{o}e^{\frac{-t}{R*C} }](https://tex.z-dn.net/?f=V_%7Bt%7D%3D%20V_%7Bo%7De%5E%7B%5Cfrac%7B-t%7D%7BR%2AC%7D%20%7D)
Voltage in this case is the energy dissipated so
![E_{t}= E_{o}e^{\frac{-t}{R*C} }](https://tex.z-dn.net/?f=E_%7Bt%7D%3D%20E_%7Bo%7De%5E%7B%5Cfrac%7B-t%7D%7BR%2AC%7D%20%7D)
![\frac{\sqrt{E_t} }{\sqrt{E_o} } = e^{\frac{-t}{R*C} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7BE_t%7D%20%7D%7B%5Csqrt%7BE_o%7D%20%7D%20%3D%20e%5E%7B%5Cfrac%7B-t%7D%7BR%2AC%7D%20%7D)
![\frac{\sqrt{3 J} }{\sqrt{5J} } = e^{\frac{-13.6ms}{10kw*C} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B3%20J%7D%20%7D%7B%5Csqrt%7B5J%7D%20%7D%20%3D%20e%5E%7B%5Cfrac%7B-13.6ms%7D%7B10kw%2AC%7D%20%7D)
Using the equation to find capacitance
![ln 0.775= e^{\frac{-13.6 x10^{3} }{10x10^{3}*C }} \\ln(0.775)= ln * e^{\frac{-13.6 x10^{3s} }{10x10^{3}*C }} \\\\ln(0.775)= {\frac{-13.6 x10^{3} }{10x10^{3}*C }} \\C= \frac{-13.6 x10^{-3} }{10x10x^{3}*ln(0.775) }](https://tex.z-dn.net/?f=ln%200.775%3D%20e%5E%7B%5Cfrac%7B-13.6%20x10%5E%7B3%7D%20%7D%7B10x10%5E%7B3%7D%2AC%20%7D%7D%20%5C%5Cln%280.775%29%3D%20ln%20%2A%20e%5E%7B%5Cfrac%7B-13.6%20x10%5E%7B3s%7D%20%7D%7B10x10%5E%7B3%7D%2AC%20%7D%7D%20%5C%5C%5C%5Cln%280.775%29%3D%20%7B%5Cfrac%7B-13.6%20x10%5E%7B3%7D%20%7D%7B10x10%5E%7B3%7D%2AC%20%7D%7D%20%5C%5CC%3D%20%5Cfrac%7B-13.6%20x10%5E%7B-3%7D%20%7D%7B10x10x%5E%7B3%7D%2Aln%280.775%29%20%7D)

C= 5.32 uF because u is the symbol for micro that is equal to ![10^{-6}](https://tex.z-dn.net/?f=10%5E%7B-6%7D)
Each parent contribute 50 percent. A person have 46 genes and 23 comes from the mother and 23 comes from the father
Density = (mass) divided by (volume)
We know the mass (2.5 g). We need to find the volume.
The penny is a very short cylinder.
The volume of a cylinder is (π · radius² · height).
The penny's radius is 1/2 of its diameter = 9.775 mm.
The 'height' of the cylinder is the penny's thickness = 1.55 mm.
Volume = (π) (9.775 mm)² (1.55 mm)
= (π) (95.55 mm²) (1.55 mm)
= (π) (148.1 mm³)
= 465.3 mm³
We know the volume now. So we could state the density of the penny,
but nobody will understand what we have. Here it is:
mass/volume = 2.5 g / 465.3 mm³ = 0.0054 g/mm³ .
Nobody every talks about density in units of ' gram/(millimeter)³ ' .
It's always ' gram / (centimeter)³ '.
So we have to convert our number for the volume.
(0.0054 g/mm³) x (10 mm / cm)³
= (0.0054 x 1,000) g/cm³
= 5.37 g/cm³ .
This isn't actually very close to what the US mint says for the density
of a penny, but it's in a much better ball park than 0.0054 was.
Answer: A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs when a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment. The size and shape of a delta is controlled by the balance between watershed processes that supply sediment.
