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
Wooden desk it doesn’t conduct or absorb heat as much as metal or plastic
Rolling friction ex. Riding a bike or skateboard
Sliding friction ex. Cartilage against your bone.
Fluid friction ex. Rowing a boat through the water.
Static friction ex. Trying to push a heavy object/ furniture

Einstein's theory of General Relativity states that space-time is able to be warped in the presence of mass or energy. This warping is what "tells" matter how to move in its presence. In the paraphrased words of physicist John Wheeler, matter tells space-time how to warp, and warped space-time tells matter how to move.
