The direction of electric field by the charge in and on the metal block will be along the direction line 5 as given in question.
<h3>
How to determine electric field direction in a metal block?</h3>
The charge always remain on outer surface of metal and inside the metal block, the net electric field is zero. But due to dipole there is an electric field at the center of metal block i.e. at point R along direction line 1.
Now, to make make the net electric field zero at center, the electric field by the charge in and on the metal block must be equal in magnitude to that of electric field due to dipole at point R and in opposite direction to that of the net electric field at at R due to dipole.
The electric field by the charge in and on the metal block will be making 180° angle to the electric field due to dipole at point R.
Hence the direction of electric field by the charge in and on the metal block will be along the direction line 5 as given in question.

I think this happens because during melting or boiling at constant temperature, the entropy dramatically increases because energy is removed from the system during the change. Entropy increases with increase in temperature, entropy increases steadily with increasing temperature up to the melting point of the solid, where the entropy increases further due to addition of freedom of molecules which increases the randomness of the substance. At boiling point of liquid, another abrupt increase in entropy occurs, this results from increased volume available to the atoms or molecules as they enter the gaseous state.
The person's velocity relative to the shore is determined as 6.5 m/s.
<h3>
Velocity of the person</h3>
The velocity of the person is calculated as follows;
V(p/f) = V(p) - V(f)
where;
- V(p/f) is the velocity of the person relative to the ferry
- V(p) is the velocity of the person
- V(f) is velocity of the ferry
1.5 = V(p) - 5
V(p) = 6.5 m/s
Thus, the person's velocity relative to the shore is determined as 6.5 m/s.

In space there is a vacuum, light travels as photons, and the see a photon it needs to bounce off of a surface to make it shine, so since the earth has an atmosphere, the light shines.
