If silicic rock is found in a core sample, its location is likely underneath an ocean or a mountain.
Answer: Option A
<u>Explanation:</u>
Silicic rock are the type of rocks which are made up of silica and are located at the crust of the earth which is more likely to the core lying underneath and it extends all the way up to 30 km.
Its density is around 2 gm / cm^3 .One of the common example of silica is granite. So if the silicic rocks are found in a core it is more likely underneath the ocean or mountain.

Explanation:
Answer:
55.3 N, 223.3 N
Explanation:
First of all, we can find the angle of the inclined plane.
We have:
L = 5 m the length of the incline
h = 1.2 m is the height
We also have the relationship

where
is the angle of the incline. Solving for the angle,

Now we can find the components of the weight of the box, which is the force that the box exerts on the plank. Calling W = 230 N the weight of the box, we have:
- Component parallel to the incline:

- Component perpendicular to the incline:
