The energy stored in a capacitor is given by:

U=\frac{1}{2}CV^2

where C is the capacitance and V is the potential difference applied across the capacitor.


In this problem, we have:

C=3000 \mu F= 3000 \cdot 10^{-6} F

V=87.0 V

Substituting the numbers into the equation, we find the energy stored:

U=\frac{1}{2}(3000 \cdot 10^{-6} F)(87 V)^2=11.4 J

A negative charge, q1, of 6 µC is 0. 002 m north of a positive charge, q2, of 3 µC. What is the magnitude and direction of the e
prohojiy [21]

Force on the particle is defined as the application of the force field of one particle on another particle. The magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.

<h3>What is electrical force?</h3>

Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.

The given data in the problem is

q₁ is the negative charge = 6 µC=6×10⁻⁶ C

q₂ is the positive charge = 3 µC=3×10⁻⁶ C

r is the distance between the charges=0.002 m

F_E is the electric force =?

The value of electric force will be;

\rm F_E= \frac{Kq_1q_2}{r^2} \\\\ F_E= \frac{9\times 10^9\times 6\times 10^{-6}\times3\times10^{-6}}{(0.002)^2}\\\\ \rm F_E=4.05\times10^4\;N

Hence the magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.

As the earth rotates through one revolution, a person standing on the equator traces out a circular path whose radius is equal t
mrs_skeptik [129]

Answer:

The average speed will be "1038 mph".

Explanation:

Period for one revolution is:

T = 24 hours

  = 86,400 sec

x = c = 2πr

The given values is:

r = 6.38×10⁶ m

Now,

⇒  T=\frac{2 \pi r}{v}

Or,

⇒  v=\frac{2 \pi r}{T}

On substituting the values, we get

       =\frac{2 \pi (6.38\times 10^6)}{86,400}

       =464 \ min/sec

       =(464 \frac{min}{sec}) (\frac{3600 \ sec}{1 \ hour} )(\frac{1 \ mi}{1609 \ m} )

       =1038 \ mph
