A capacitor is formed from two concentric spherical conducting shells separated by vacuum. The inner sphere has radius 10.5 cm,

Step2247 [10]

Answer:

$U = 2.91 *10^{-5} J$

Explanation:

energy density can be obtained as

$U = \frac{1}{2}\epsilon_o E^{2}$

Where,

E is electric field $= \frac{kQ}{R^{2}}$

K COLOUMB CONSTANT =8.99*10^{9} N -m2 /C2

Q is charge = CV

C is capacitance = $4\pi \epsilon_o \frac{r_1 r_2}{r_2 -r_1}$

$=4\pi *8.85*10^{-12} [\frac{10.5*16.5}{16.5 -10.5}]$

$= 3.21*10^{-9} F$

$Q = 3.21*10^{-9} *150 = 4.81*10^{-7] C$

for r = 10.6 cm

$E = \frac{8.99*10^{9}*3.21*10^{-9}}{0.106^{2}}$

E = 2568.34 N/C

$U = \frac{1}{2}\epsilon_oE^{2}$

$U = \frac{1}{2}*8.85*10^{-12} *2568.34 ^2$

$U = 2.91 *10^{-5} J$

If a certain mass has its velocity changed from 6.00 m/s to 7.50 m/s when a 3.00 n force acts for 4.00 seconds, find the mass of

shutvik [7]

By definition we have that the force for time is equal to the product of the mass for the change in speed.
We have then that
F * (delta t) = m * (delta v)
Clearing the mass
m = (F * (delta t)) / (delta v)
Substituting the values
m = ((3.00) * (4.00)) / (7.50-6.00) = 8
answer
The mass of the moving object is 8Kg

How much water is stored in groundwater lakes rivers soil and streams

Ne4ueva [31]

Answer:

Explanation:

Most of this water is locked up in ice, and another 20.9% is found in lakes. Rivers make up 0.49% of surface freshwater. Although rivers account for only a small amount of freshwater, this is where humans get a large portion of their water from.
