Answer:
This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases We have the inner core, outer core, mantle and crust which play an important role on Earth.
Answer:
1) The force per egg caused by the weight of the block is 17.15 N
2)
Explanation:
<u>Pressure</u>
The pressure is computed as the force acting upon a surface divided by the area of the surface
:
The weight of an object of mass m is:
W = mg
Where g is the gravitational acceleration of
The cement block has a mass of m=14 kg, thus its weight is:
W = 14*9.8
W = 137.2 N
1) This weight is evenly distributed over the 8 eggs, thus the force per egg is:
F = 137.2 N/8= 17.15 N
The force per egg caused by the weight of the block is 17.15 N
2) It's given the pressure on each egg as and we know the force acting on each one is F=17.15 N. To find the contact area we solve the formula of the pressure for A:
