If Faraday had used a more powerful battery in his experiments with electromagnetic induction, what effect would this have had o

dmitriy555 [2]

Answer:

The value of current generated would increase.

Explanation:

Electromagnetic induction is the process by which an electromotive force is induced due to a variation of magnetic field.

The induced current is directly proportional to rate at which the coil cuts the magnetic field. Using more powerful battery in the experiment would increase the rate at the the coil cuts the magnetic field, therefore increasing the rate of variation in the magnetic field. This effect would cause a greater deflection on the galvanometer's scale, showing an increase in the current generated.

This experiment proves that an alternating current can be produced from magnetic field.

A positive point charge Q is located at x=a and a negative point charge −Q is at x=−a. A positive charge q can be placed anywher

Scilla [17]

Answer:

$\vec{F}_x = \frac{2KQqa}{(a^2 + y^2)^{3/2}} \^x$

Explanation:

The Coulomb's Law gives the force by the charges:

$\vec{F} = K\frac{q_1q_2}{r^2}\^r$

Let us denote the positon of the charge q on the y-axis as 'y'.

The force between 'Q' and'q' is

$F_1 = K\frac{Qq}{x^2 + y^2}\\F_1_x = F_1\cos(\theta)$

where Θ is the angle between $F_1$ and x-axis.

$F_1_x = K\frac{Qq}{x^2 + y^2}(\frac{x}{\sqrt{x^2 + y^2}}) = \frac{KQqa}{(a^2 + y^2)^{3/2}}$

whereas

$F_2_x = K\frac{-Qq}{a^2 + y^2}(-\frac{a}{\sqrt{a^2 + y^2}}) = \frac{KQqa}{(a^2 + y^2)^{3/2}}$

Finally, the x-component of the net force is

$\vec{F}_x = \frac{2KQqa}{(a^2 + y^2)^{3/2}} \^x$

How much work is required to turn an electric dipole 180° in a uniform electric field of magnitude E = 46.0 N/C if the dipole mo

chubhunter [2.5K]

Answer:

$W=1.22*10^{-23}J$

Explanation:

Torque and energy of an electric dipole in an electric field we find:

$W=U(\alpha_{o}+\pi )-U(\alpha_{o} )=-pE(cos(\alpha_{o}+\pi )-cos(\alpha_{o} ))\\W=2pECos\alpha_{o}\\ W=2(3.02*10^{-25}C.m )(46.oN/C)Cos64\\W=1.22*10^{-23}J$
