They are all related to what time of year it is.
Answer:

Explanation:
energy density can be obtained as

Where,
E is electric field 
K COLOUMB CONSTANT =8.99*10^{9} N -m2 /C2
Q is charge = CV
C is capacitance = 
![=4\pi *8.85*10^{-12} [\frac{10.5*16.5}{16.5 -10.5}]](https://tex.z-dn.net/?f=%3D4%5Cpi%20%2A8.85%2A10%5E%7B-12%7D%20%5B%5Cfrac%7B10.5%2A16.5%7D%7B16.5%20-10.5%7D%5D)

![Q = 3.21*10^{-9} *150 = 4.81*10^{-7] C](https://tex.z-dn.net/?f=Q%20%3D%203.21%2A10%5E%7B-9%7D%20%2A150%20%3D%204.81%2A10%5E%7B-7%5D%20C)
for r = 10.6 cm

E = 2568.34 N/C



Answer:

Explanation:
m = Mass of bungee jumper = 55 kg
g = Acceleration due to gravity = 
h = Height at the bottom = 40 m
k = Spring constant
x = Displacement of bungee cord = 25 m
Applying the principle of conservation of energy to the system we have

The spring constant of the bungee cord is
.
The answer for this problem is clarified through this, the
system is absorbing (+). And now see that it uses that the SURROUNDINGS are
doing 84 KJ of work. Any time a system is overshadowing work done on it by the
surroundings the sign will be +. So it's just 12.4 KJ + 4.2 = 16.6 KJ.
