Answer:

Explanation:

Applying the Heisenberg uncertainty principle,

Δx X mΔv = h/4π

where Δx = uncertainty in measurement of position

Δv = uncertainty in measurement of velocity

m = mass of object

h = planck's constant

Here:

Δv = 0.4 A° = 4.0 x 10^-11 m

mass, m = 9.11 x 10^-31 Kg

Plugging the values,

4.0 x 10^-11 x Δ v = (6.626 x 10^-34) / (4 x 3.14 x 9.11E-31)

4.0 x 10^-11 x Δ v = 5.791 x 10^-5

Δv = 1.448 x 10^6 m/s, the uncertainty in its velocity

Answer = 1.45 x 10^6 m/s

3. Describe how the water at the equator would be different from the<br> water at the poles.
Dmitry_Shevchenko [17]

Answer:

there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis. As a result, the fresh water falling into the ocean helps decrease the salinity of the surface water in that region.
