A sinusoidally oscillating current I ( t ) with an amplitude of 9.55 A and a frequency of 359 cycles per second is carried by a

UNO [17]

Answer:

$P_{avg} = 6.283*10^{-9} \ W$

Explanation:

Given that;

I₀ = 9.55 A

f = 359 cycles/s

b = 72.2 cm

c = 32.5 cm

a = 80.2 cm

Using the formula;

$\phi = \frac{\mu_o Ic }{2 \pi} In (\frac{b+a}{b})$

where;

$E= \frac{d \phi}{dt}$

$E = \frac{\mu_o}{2 \pi}c In (\frac{b+a}{a}) I_o \omega cos \omega t$

$E_{rms} = \frac { {\frac{\mu_o \ c}{2 \pi} In (\frac{b+a}{a}) I_o (2 \pi f)}}{\sqrt{2}}$

Replacing our values into above equation; we have:

$E_{rms} = \frac { {\frac{4 \pi*10^{-7}*0.325}{2 \pi} In (\frac{72.2+80.2}{80.2}) *9.55 (2 \pi *359)}}{\sqrt{2}}$

$E_{rms} = \frac {8.98909588*10^{-4} }{\sqrt{2}}$

$E_{rms} = 6.356*10^{-4} \ V$

Then the $P_{avg$ is calculated as:

$P_{avg} = \frac{E^2}{R}$

$P_{avg} = \frac{(6.356*10^{-4})^2}{64.3}$

$P_{avg} = 6.283*10^{-9} \ W$

An electron starts from rest in a vacuum, in a region of strong electric field. The electron moves through a potential differenc

Semenov [28]

Answer:

The kinetic energy is $KE = 5.67*10^{-18} \ J$

Explanation:

From the question we are told that

The potential difference is $\Delta V = 36 \ volts$

The potential energy of the end is mathematically represented as

$PEs = - q * \Delta V$

q is the charge on an electron with a constant value of $q = 1.60 *10^{-19} \ C$

substituting values

$PE = - 1.60*10^{-19} * 36$

$PE = - 5.67*10^{- 18} \ J$

Now from the law of energy conservation

The $PE_e = KEe$

Where $KE _e$ is the potential energy at the end

$KE = 5.67*10^{-18} \ J$

The negative sign is not includes because kinetic energy can not be negative
