Answer:
dV = 32.98 cm³
Explanation:
We know that
V = f ( h,r)
We also know that
Given that
h= 10 cm
d=10 cm , r= 5 cm
Thickness = 0.05 cm so dr = 0.05 cm
The metal in the top and the bottom is 0.2 cm thick so dh = 0.2 + 0.2 cm
dh = 0.4 cm
Now by putting the values
dV = 32.98 cm³
Answer:
Explanation:
Given data
Q₁=200cm³/s
We know that:
can be written as:
ΔP=F/A=n×v/L
And
Q=ΔP/R
As
n₂=6.0n₁
So
Q=ΔP/R
Answer:
B. Landscape B
Explanation:
Shale is fine sediment pressed together to form rock.
Sandstone is larger (sand-grain-sized) sediment cemented together to form rock.
Shale erodes faster, as evidenced by the second attachment. That attachment shows erosion of a rock face consisting of interbedded shale and sandstone. The shale has receded significantly, leaving the sandstone layers with space between them.
