Option c. are large
Igneous rocks are crystalline solids which are formed after the magma cools. The sizes vary greatly depending on how quickly the magma cooled. The slower the cooling, the larger the crystals in the final rock. They cooled at depth in the crust where they were insulated by layers of rock and sediment.
I am not so sure about this it is too difficult
a boulder can change due to erosion and weathering. it can change shape and sometimes color, possibly.
Answer:
The y-component of the electric force on this charge is
Explanation:
<u>Given:</u>
- Electric field in the region,
- Charge placed into the region,
where, are the unit vectors along the positive x and y axes respectively.
The electric field at a point is defined as the electrostatic force experienced per unit positive test charge, placed at that point, such that,
Thus, the y-component of the electric force on this charge is
