The seventh planet from the sun is Uranus.
Answer: Option B
Explanation:
Rocks contains pores and spaces in them in which water gets trapped, and this causes the rock to break as water increases its volume due to freezing. This rocks are then eroded and are carried away into the streams and channels. The rivers and streams can carry particles of various shapes and size, which are further transported and deposited at a different place.
This particles or sediments then gets compacted and lithified in due course of time, and forms sedimentary rocks.
Water is also needed to undergo metasomatism process, that creates a metamorphic rock.
Hence, water flow is also an important driving force in rock cycle, along with tectonic activities.
Thus, the correct answer is option (B).
1. Dump the container out.
2. Sift the large items out until the sugar and gravel is by itself.
3. Continue separating the other items.
Answer:
192000 J or 192 kJ
Explanation:
Work done = Force × distance moved along the direction of force.
From the question,
W = F×d............... Equation 1
Where W = work done by the car, F = Force of the car, d = distance move by the car along the direction of the force.
We can calculate for d using the equation of motion
d = (v+u)t/2..................... Equation 2
Where v = Final velocity of the car, u = Initial velocity of the car, t = time.
Given: u = 12 m/s, v = 0 m/s(skids to a stop), t = 4.0 s
Substitute into equation 2
d = (12+0)4/2
d = 24 m.
Also given: F = 8000 N
Substitute into equation 1
W = 8000×24
W = 192000 J
W = 192 kJ.
