Oceania crust is typically made up of igneous rocks such as basalt. Igneous rocks are formed when lava flows from volcanoes cool and harden.
Answer:

Explanation:
<u>Given:</u>
- Initial temperature,

- Final temperature,

- Diameter of the hole,

- Expansion coefficient of the Aluminum,

Let the diameter of the rivet at
be
, such that,

is the elongation in the diameter of the rivet.
We know, The change in the diameter of the rivet is related with the change in temperature as:

where,
is the change in temperature = 
Also, 
Using these values,

It is the required diameter of the rivet at
.
Answer:
A) The particle will accelerate in the direction of point C.
Explanation:
As we know that
potential at points A, B,C and D as V_A, V_B, V_C, V_D and it is clear from the question that
V_A>V_B>V_C
And we know that flow is always from higher to lower potential (for positive charge due to positive potential energy).
So the charge will accelerate from B toward C.
Hence, the correct option is A.
