To develop this problem we require the concepts related to Frequency and their respective way of calculating it.
The formula to calculate the frequency is given by
Where,
For fundamental mode, wavelength is equal to 4 time the length.
Then,
Replacing in the first equation,
Therefore the frequency is 96.12Hz
Answer:
2.62 A
Explanation:
B = 2 T, Diameter = 2.5 cm , radius, r = 0.0125 m, t = 0.45 s, r = 0.01 ohm
Induced emf, e = rate of change of magnetic flux
e = A x dB / dt = 3.14 x (0.0125)^2 x 2 / 0.45
e = 0.026 V
induced current, i = e / R = 0.026 / 0.01 = 2.62 A
Answer:
44 years
Explanation:
Use half life equation:
A = A₀ (½)^(t / T)
where A is the final amount,
A₀ is the initial amount,
t is time,
and T is the half life.
0.25 A₀ = A₀ (½)^(t / 22)
0.25 = (½)^(t / 22)
t / 22 = 2
t = 44
Change in velocity per time
