Answer:
Given:
m = 12 g, the mass of the cylinder
r = 2 cm, the radius of the cylinder
h = 6 cm, the height of the cylinder.
Calculate the volume, V, of the cylinder.
V = πr²h
= π*(2 cm)²*(6 cm)
= 75.398 cm³
By definition,
density = mass/volume.
Therefore,
density = m/V
= (12 g)/(75.398 cm³)
= 0.159 g/cm³
= 0.16 g/cm³ (nearest hundredth)
Answer: 0.16 g/cm³
The answer to your question is option 1. I hope this has helped.
Answer:
Weather and erosion.
Explanation:
In Geography, weathering is the process of breaking down of rocks, minerals and soil as a result of contact with water, earth's atmosphere, acid, ice, plants and animals. The breaking up of the rocks by weathering weakens it and makes it susceptible to erosion.
Erosion in geography is the movement of rocks and sediments to another place by water, wind and ice.
For instance, In many parts of the Cross Timbers and Prairies ecoregion, the Brazos river has formed tall, steep cliffs in the rock along its banks through the processes of weathering and erosion.
Answer: Ok I think The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Carbon, or 12.0107 grams. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between moles Carbon and gram. 12 grams
This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.
hope this helps have a awesome night/day❤️✨
Explanation:
To convert from grams to moles, you divide the number of grams by the molar mass To convert from moles to grams, you multiply by the molar mass. You must first calculate the molar mass of the substance
