In the Bohr model of the hydrogen atom, an electron in the 8th excited state moves at a speed of 3.42 104 m/s in a circular path having a radius of 3.39 10-9 m. What is the effective current associated with this orbiting electron

I=1.6x10-19A

Explanation:

Given Info: Electron in its lowest energy

state moves with the velocity

2.19x 10" m. s in a circular orbit of

radius 5.29 x 10" m, Electron in its lowest

energy state moves with the velocity

2.19 x 10 m-s" in a circular orbit of

radius 5.29 x 10- m.

Explanation:

Formula to calculate the time period of

electron is,

T:

2TT

21

Tis the time period of electron,

ris the radius of circular orbit,

vis the velocity of electron,

Substitute 3.14 for T, 5.29 x 10- m for r

and 2.19x 10 m s for v in the above

equation to find T.

T23.14) (5.29 x 10-1 m)

T-

2.19x10 ms

= 1

Let the current be:

I

=

d

Q

d

t

Where Q is the charge.

If rate of flow of charge is not constant then the current at any instant is given by the differential limit: I = dQ/dt.

If a charge Q flows through the circuit for time t, then

 I = Q/t.

Charge of hydrogen atom q = 1.6x10–19C

T = 1

Therefore,

I = 1.6 x 10-19C/1

I=1.6x10-19A

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
