Answer:
The correct answer is detritic rocks.
Explanation:
Sedimentary rocks are rocks formed by the accumulation of sediments, particles of various sizes that are transported by water, ice or wind, which are subjected to physical and chemical processes, resulting in consolidated materials.
Sedimentary rocks formed from the accumulation of mineral deposits and rocks from erosion and deposited by gravity are called detritic rocks.
Have a nice day!
4x time 10x (I think)
Here, this will help-

We use the formula, to calculate the average speed of the round trip,
Here, , is total distance covered by plane in total time, .
For the round trip,
.
Thus,
.
To develop this problem we will apply the concepts related to the conservation of momentum. For this purpose, the initial momentum will be equivalent to the initial momentum of the two objects when they have the same speed. Mathematically this can be expressed as,
Where,
= Mass of bullet
= Velocity of bullet
= Mass of wooden block
Velocity of Wooden block
Inititally then we have that the expression can be rearrange to find the velocity of the bullet,
Replacing with our values
Therefore the velocity of the bullet before striking the block is 319.6m/s
