The first step in the formation of sedimentary rock is weathering of preexisting rocks. The second step is transport of the weathering products. The third step is deposition of the material. And at the end there is compaction and cementation of the sediment to form a rock.
According to this, the following shows the correct order of steps in the formation of sedimentary rocks:
C. <span>1, 4, 3, 2
</span>Rocks are weathered.Small pieces of rocks are carried by water.They are deposited in layers.<span>The sediments are compacted together.</span>
The resultant of the two vectors is 5 units (see attachment)
Explanation:
When we have to calculate the resultant of two vectors, we can do the following:
- Graphically, we have to draw the two vectors, connected head-to-tail (this means, the tail of the second vector starts from the head of the first vector). The resultant vector is found by connecting the tail of the first vector to the head of the second vector. In this example, we called A the first vector of 3 units and B the second vector of 4 units: the rresultant vector is shown in the picture as vector R.
- Numerically, we start by noticing that the two vectors are at 90 degrees to each other. Therefore, they form the sides of a right triangle, of which the resultant is the hypothenuse.
Therefore, we can find the resultant by using Pythagorean's theorem. Using
A = 3
B = 4
We find:
So, the resultant is 5 units.

3. Newton's third law
5. Conservation of momentum
<u>Explanation:</u>
Conservation of momentum is mostly used for describing collisions between objects. Here, the type of collision is inelastic collision in which the object when collides with the pendulum bob sticks to it and moves as a combined object. In this process the momentum is conserved.
Let the mass of the pendulum be m1 moving with a velocity v1.
Let the mass of the object be m2 moving with a velocity v2.
Since the momentum is conserved during collision, the equation will be
Where, v is the velocity of the combined system.
Conservation of momentum is actually a direct consequence of Newton's third law.
Consider a collision between two objects, object A and object B. When the two objects collide, there is a force on A due to B. However, because of Newton's third law, there is an equal force in the opposite direction, on B due to A
FAB = -FBA
The mechanical energy is not conserved due to the fact that the kinetic energy is not the same before and after the collision.
Answer:
5.36 times bigger
Explanation:
The radius of the Earth is:
so its diameter is
The radius of Pluto is:
So its diameter is
So the ratio between the two diameters is
So the diameter of the Earth is 5.36 times bigger than the diameter of Pluto.
