Answer:
oo.p i wish I could answer that
Explanation:
By definition, the potential energy is:
U = qV
Where,
q: load
V: voltage.
Then, the kinetic energy is:
K = mv ^ 2/2
Where,
m: mass
v: speed.
As the power energy is converted into kinetic energy, we have then:
U = K
Equating equations:
qV = mv ^ 2/2
From here, we clear the speed:
v = root (2qV / m)
Substituting values we have:
v = root ((2 * (1.60218 × 10 ^ -19) * 3600) /9.10939×10^-31))
v = 3.56 × 10 ^ 7 m / s
Then, the centripetal force is:
Fc = Fm
mv ^ 2 / r = qvB
By clearing the magnetic field we have:
B = mv / qr
Substituting values:
B = (9.10939 × 10 ^ -31) * (3.56 × 10 ^ 7) / (1.60218 × 10 ^ -19) * 0.059
B = 3.43 × 10 ^ -3 T
Answer:
A magnetic field that must be experienced by the electron is:
B = 3.43 × 10 ^ -3 T
<span>Since frequency and wavelength have inverse relationship. It can be expressed by the equation:
ν.λ = c
Where,
v = frequency of the electromagnetic wave.
λ = it's wavelength
c = the speed of light in a vacuum.
v = 2.00 Ghz x 10^9 Hz / 1 Ghz = 2.00 x 10^9 Hz
that means that in one second it covers 2.00 x 10^9 cycles.
λ = 3.10^8 m/s / 2.00 x 10^9 /s = 1.25E-10 nanometers</span>
2 J / 4 C = 1/2 joule per coulomb.
That's 1/2 volt.
<span>Is more than one displacement possible?
No, displacement only considers the initial and final position.
Is more than one average velocity possible?
No, the average velocity is defined as displacement per time and since there is only one displacement possible, there is only one average velocity possible as well.
Is more than one average speed possible?
Yes, the average speed considers the total distance traveled and this distance may not be the same as the total displacement.
