If the time for 20 vibrations is 100 second then find
Lilit [14]

hey guy

the vibration per second is frequency

then for 20 vibration time taken is 100 second

in 1 second 20/100 vibration took place

it means 0.2 is frequency

for time period , we have

t=1/f

=1/0.2

=5

In the Bohr model of the hydrogen atom, an electron in the 7th excited state moves at a speed of 4.47 104 m/s in a circular path
tekilochka [14]

Answer:

I = 4.38 x 10⁻⁷ A

Explanation:

Given,

speed = 4.47 x 10⁴ m/s

radius of the circular path, r = 2.59 x 10⁻⁹ m

effective current = ?

The current represented by the orbiting electron is equal to

I = q \times f

f is the frequency

q is charge of electron

we know,

f = \dfrac{v}{2\pi r}

f = \dfrac{4.47\times 10^{4}}{2\pi\times 2.59\times 10^{-9}}

f = 2.74 x 10¹² Hz

now,

I = 1.6 \times 10^{-19}\times 2.74\times 10^{12}

I = 4.38 x 10⁻⁷ A

Hence, the effective current associated with the orbiting electron is equal to I = 4.38 x 10⁻⁷ A
