Answer:
The star is too distant to be measured by parallax method. This happens when parallax angle is of the order of the least count of measuring system or less than that.

Answer:
A rift valley is forming.
Explanation:
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault.
A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface.
The arrows show the movement of the tectonic plates.

Answer:
b) V_CD = - V_AB
, c) V_AD = -2 V_AB
Explanation:
b) In this exercise of potential differences they indicate that the diagonal potential is the negative of the leg potential
V_AC = - V_AB
V_BD = - V_CD
Thus
V_CD = V_AC
Finally
V_CD = - V_AB
c) The potential is a scalar quantity so it can be added algebraically, they give us the condition
V_AC = -V_AB
V_AB + V_BC = - V_AB
V_BC = - 2 V_AB
For the other triangle
V_BD = V_AC
V_AB + V_AD = V_AC
We replace
V_AB + V_AD = - V_AB
V_AD = -2 V_AB
