What is the uncertainty of the position of the bacterium? express your answer with the appropriate units?

1 answer:

4 0

For two un-related quantities, the Heisenberg uncertainty equations holds: the prduct of the two uncertainty quantities is greater than $\hbar/2$
Example of unrelated quantities are position and momentum, energy and time.
Thus
$\Delta x*\Delta p \ \textgreater \ \hbar/2$
Knowing the speed of the bacteria the uncertainty in its position is
$\Delta x \ \textgreater \ \hbar/(2 \Delta p) =\hbar/(2mv)$

luda_lava [24]

Answer:

Explanation:

|F-->1| = E-->1 x charge on proton

= 300 x 1.6 x 10⁻¹⁹

Magnitude of electric force on proton

|F-->1| = 480 x 10⁻¹⁹ N .

Inside lithium nucleus , there are three protons so charge on it

= 3 x 1.6 x 10⁻¹⁹ = 4.8 x 10⁻¹⁹ C .

Magnitude of electric force on lithium nucleus

|F-->Li| = E-->1 x charge on lithium nucleus

= 300 x 4.8 x 10⁻¹⁹

= 1440 x 10⁻¹⁹ N .

Electron has same charge as that possessed by proton so charge on electron = 1.6 x 10⁻¹⁹ C

Magnitude of force on electron

|F-->1| = E-->1 x charge on electron

= 300 x 1.6 x 10⁻¹⁹

= 480 x 10⁻¹⁹ N .

AleksAgata [21]

Fluorine (F) has higher potential energy as Neon (N) is a noble/inert gas.

Fluorine will lose another electron to gain stability.

Razona si, en las experiencias de Faraday, el efecto producido moviendo el circuito será el mismo que el producido moviendo el i

const2013 [10]

Answer:

moving the circuit or the magnet gives the same result

Explanation:

The faraday effect establishes that the temporal variation of imaginative flow produces an electric potential

fem = $\frac{d \phi }{dt}$ dfi / dt

the magnetic flux is

Ф = B. A = B A cos θ

suppose for simplicity that the angle is zero so cos 0 = 1

Φ = B A

By analyzing this expression, the change in magnetic flux can converge while keeping the magnetic field fixed and varying the electric field or keeping the electric field fixed and varying the magnetic field.

Consequently moving the circuit or the magnet gives the same result
