In order to induce electrical energy into a conductor or generator, what three factors must be present?

salantis [7]4 years ago

The electricity produced by a generator works through the concepts of the following three factors; magnetic field, voltage and current. When a conductor with current flowing in it is placed in a magnetic field, it will cause the electrons to move in a direction perpendicular to the magnetic field. When working with generators, the guide for this direction is Fleming's Right Hand Rule. Since the electron move in perpendicular motion with magnetic field all the time, it would cause it to spin in a helical direction. These turns would then induce voltage and create electricity.

The electrostatic force between two small charged particles is 5.2 x 10^-7 N at a distance of 2 meters. What will be the new for
Kamila [148]

Answer:

F_2=1.3\times 10^{-7}\ N

Explanation:

Given that,

Initial force, F=5.2\times 10^{-7}\ N

distance, d = 2 m

New distance, d' = 4 m

We need to find the new force. The electrostatic force between two charges is given by :

F=k\dfrac{q_1q_2}{d^2}

So,

\dfrac{F_1}{F_2}=(\dfrac{d_2}{d_1})^2\\\\\dfrac{F_1}{F_2}=(\dfrac{4}{2})^2\\\\\dfrac{F_1}{F_2}=4\\\\F_2=\dfrac{F_1}{4}\\\\F_2=\dfrac{5.2\times 10^{-7}}{4}\\\\F_2=1.3\times 10^{-7}\ N

So, the new force is equal to 1.3\times 10^{-7}\ N.

The half-life of Actinium 227 decays in 20 years. Calculate the mass of the element left when a 2kg sample was left for 160 year
nataly862011 [7]

The mass of Actinium 227 left is 0.0078 kg

Explanation:

The amount of mass left of a radioactive isotope after time t is given by the equation:

m(t) = m_0 (\frac{1}{2})^{-\frac{t}{\tau_{1/2}}}

where

m_0 is the initial amount of the sample

t is the time

\tau_{\frac{1}{2}} is the half-life of the isotope

For the sample of Actinium 227 in this problem,

m_0 = 2 kg

\tau_{1/2}=20 years

t = 160 years

Substituting into the equation,

m(160) = (2 kg) (\frac{1}{2})^{-\frac{160}{20}}=0.0078 kg
