How much has the depth of the lettering been reduced on each tombstone?
The depth of the lettering been reduced on each tombstone if the average rate of chemical weathering of carbonate rock in an urban area is
Answer to Problem 2PEB
Solution:
Explanation of Solution
Given data:
The average rate of chemical weathering of carbonate rock in an urban area is
The depth of lettering of the tomstones shown in the following table was measured by 2010.
Formula used:
Write the weathering rate is divided by the surface reduction by the age of the tombstone.
Explanation:
Recall that the weathering rate is divided by the surface reduction by the age of the tombstone.
Rearranged:
For date of tombstone 1920 and age
Substitute
For date of tombstone 1921 and age
Substitute
For date of tombstone 1948 and age
Substitute
For date of tombstone 1958 and age
Substitute
For date of tombstone 1975 and age
Substitute
Conclusion:
The depth of the lettering been reduced on each tombstones are

- Explorers in the jungle find an ancient monument in the shape of a large isosceles triangle as shown in the figure below. The monument is made from tens of thousands of small stone blocks of density3 633kg/m3. The monument is16.7m high and68.5m wide at its base and is everywhere3.70m thick from front to back. Before the monument was built many years ago, all the stone blocks lay on the ground. How much work did laborers do on the blocks to put them in position while building the entire monument?Note: The gravitational potential energy of an object-Earth system is given byUg=MgyCM, whereMis the total mass of the object andyCMis the elevation of its center of mass above the chosen reference level.Jarrow_forwardAn element makes up 0.0021% of the Earth's continental crust by mass.
