What is the difference between cementation and compaction?

Physics
1 answer:

Compaction is when sediments are buried deeply, which causes pressure because of the weight of the layers above them.  This squashes the grains together more tightly.  Cementation is where new minerals stick the grains together

A bakery measured the mass of a whole cake as 0.870 kg. A customer bought one slice of the cake and measured the mass of the sli
Brrunno [24]

Answer:

0.7549kg

Explanation:

The mass of the slice + mass of the remaining cake = total mass of cake.

mass of remaining cake = total mass of cake - the mass of the slice

total mass=0.870kg

mass of slice = 0.1151kg

mass of remaining cake = 0.870 - 0.1151

mass of remaining cake=0.7549kg

What is the magnitude of your displacement when you follow directions that tell you to walk 100.0m north, then 25.0m East?
atroni [7]

Answer:

Displacement from the starting position is 103.21m

Explanation:

If you draw these directions, it will create the two legs of a triangle.

Using this method, you can visualize why your displacement is what it is.

Using the pythagorean theorem

{a}^{2}  +  {b}^{2}  =  {c}^{2}

Plug in both values

{100m}^{2}  +  {25m}^{2}  =  {c}^{2}

c =  \sqrt{10652}

c = 103.2085

c= 103.21
