The answer is mole.
Kelvin- temperature
Ampere- electric current
Mole- amount of substance
Pound- mass
With the passage of time, the rock wall would be weathered under the impact of flowing water and would receede backwards.
Explanation:
Given details=
Water flowing at the pace of 2 to 3 feet per sec
It must be understood that flowing water act as an erosive agent here.
As the water flows, it carries with itself erosive tools which erode the rock surface. Since the speed of water is considerable, the erosion is quite significant. Due to the erosive action of the river, the rock wall would be continuously eroded starting from the tip and in turn, would recede backwards (in the upstream direction).
Theres monocotyledons and dicotyledons. (1 and 2 cots)
the answer should be monocotyledons, we can see that through the leaves and the petals. monocotyledons the petals r usually in the multiples of 3 or 6, and 9 petals is the multiple of 3. also, monocots leaves r usually in parallel leaf veins, so your plant is monocotyledons, which means one.
just in addition, dicots petals r in multiples of 4 or 5, and their leaves r usually in branched veins
