Answer:
The uncertainty in the location that must be tolerated is
Explanation:
From the uncertainty Principle,
Δ Δ
The momentum P = (mass of electron)(speed of electron)
=
=
If the uncertainty is reduced to a 0.0010%, then momentum
=
Thus the uncertainty in the position would be:
Δ
Δ
B. At the equator
Explanation:
The energy coming from the Sun hits the Earth's surface at different angles, depending on the latitude of the place. The more perpendicular the ray of lights hit the surface, the more the energy transmitted to the Earth's surface, the warmer the location.
The angle at which the ray of lights hit the Earth is related to the latitude: in particular, the ray of lights arrive perpendicular at the equator (), they arrive at larger angle in the United States (which is located at intermediate latitudes) and they arrive at the largest angles at the poles. For this reason, the sun's most energy is concentrated at the equator.
