Craters, highlands and maria are the moon's three main landforms
Answer:
E. The gas absorbs 50 of energy as heat and does 50」ot work
Explanation:
This is following the law of thermodynamics that energy is neither created nor destroyed
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).
Answer:
200 km/h
Explanation:
Because the train is travelling 1000 km in 5 hours, you simply divide 1000 by 5, giving you 200 km/h. This is about 124.27 mph.
Answer:
Explanation:
a ) 12.0 lbs - mass
b ) .34 g - mass
c ) 120 kg - mass
As lbs , g and kg are units of mass , these things represent mass . lbs is FPS unit of mass and kg is SI unit . g is CGS unit of force .
d ) 1600 kN It represents force because kN or kilonewton is unit of force .
e ) it represents , length or distance because m or metre is unit of length .
f ) 411 cm It represents length or distance because cm is smaller unit of length
g ) 899 MN or million newton . Like d ) It also represents force . Million newton is higher unit of force .
