A set of four capacitors are attached to a 12V battery in the circuit shown below. All capacitances are measured in milli-Farads

Bond [772]

The amount of electric charge that resides on each capacitor once it is fully charged is 0.37 C.

<h3>Total capacitance of the circuit</h3>

The total capacitance of the circuit is calculated as follows;

Capacitors in series;

1/Ct = 1/8 + 1/7.5

1/Ct = 0.25833

Ct = 3.87 mF

Capacitors is parallel;

Ct = 3.87 mF + 12 mF + 15 mF

Ct = 30.87 mF

Ct = 0.03087 F

<h3>Charge in each capacitor</h3>

Q = CV

Q = 0.03087 x 12

Q = 0.37 C

Thus, the amount of electric charge that resides on each capacitor once it is fully charged is 0.37 C.

You have designed and constructed a solenoid to produce a magnetic field equal in magnitude to that of the Earth (5.0 10-5 T). I

saul85 [17]

Answer:

$I = 0.03637 A$

Explanation:

The given data in the question is

Magnetic field : $B = 5.0 \times 10^{-5} T$

Turns : $N = 350$

Length : $L = 32 cm = 0.32 m$

So, number of turns per unit length :

$n=\frac{N}{L}$

$n=\frac{350\: turns}{0.32 m}$

$n=1093.75 \: turns \: per \: meter$

If current is I , then magnetic field is given by

$B = \mu_{0} \times n \times I$

Also,

$I = \frac{B}{\mu_{0} \times n}$

Insert the values

$I = \frac{5.0 \times 10^{-5}}{4 \pi \times 10^{-7} \times 1093.75} A$

$I = 0.03637 A$

The current will be $I = 0.03637 A$

How many excess electrons must be distributed uniformly within the volume of an isolated plastic sphere 25.0 cm in diameter to p

katrin [286]

Answer:

Required charge $q=2.6\times 10^{9}C$ .

$n=1.622\times 10^{10}\ electrons$

Explanation:

Given:

Diameter of the isolated plastic sphere = 25.0 cm

Magnitude of the Electric field = 1500 N/C

now

Electric field (E) is given as:

$E =\frac{kq}{r^2}$

where,

k = coulomb's constant = 9 × 10⁹ N

q = required charge

r = distance of the point from the charge where electric field is being measured

The value of r at the just outside of the sphere = $\frac{25.0}{2}=12.5cm=0.125m$

thus, according to the given data

$1500N/C=\frac{9\times 10^{9}N\times q}{(0.125m)^2}$

$q=\frac{0.125^2\times 1500}{9\times 10^{9}}$

Required charge $q=2.6\times 10^{9}C$ .

Now,

the number of electrons (n) required will be

$n=\frac{required\ charge}{charge\ of\ electron}$

$n=\frac{2.6\times 10^{-9}}{1.602\times 10^{-19}}$

$n=1.622\times 10^{10}\ electrons$

SVETLANKA909090 [29]

Answer:

The answer to your question is:

a) h max = 529.7 m

b) t = 20.4 s

c) t = 20.6 s

Explanation:

a) h max = -(vo)² / 2g

= 100² / 2(9.81)

= 10000 / 19.62

= 509.7 m

total height = 509.7 + 20 = 529.7 m

h = gt² / 2

t = √ 2h / g

t = √ 2(509.7)/9.81

t = √ 103.91

t = 10.19 s

total time = 2 x t = 2 x 10.19 = 20.4 s

h = vot + 1/2gt²

20 = 100t + 1/2(9.91) t²

4.9t² + 100 t -20 = 0 quadratic equation

t = 0.19 s

Total time = 0.19 + 20.4 = 20.6 s
