Answer:10,0000 years
Explanation:
If it takes 2000 years to weather 1cm of limestone
It will take 5*2000 years to weather 5cm of limestone. This gives us 10000 years.
Answer:
12
Explanation:
If GT bisects BN at point G, then point G would be in the middle of BN. So, since Bg and NG have to be equal and add up to 24, then the answer is 12.
Answer:
a) The volume is 5.236x10⁻¹³L
b) The molarity of a single virus is 1.91x10¹² mol/L
c) The molarity for a 100 virus particles is 1.91x10¹⁴ mol/L
Explanation:
a) Given:
D = diameter of the cell = 10 μm
r = radius = 10/2 = 5 μm
The volume of the spherical cell is equal:

If 1 μm³ = 1x10⁻¹⁵L, then 523.6 μm³ = 5.236x10⁻¹³L
b) The molarity is:

For a single virus within the cell

c) For a 100 virus particles the molarity is:

Answer:
Ki = 30atmL
Kf = 30atmL
Explanation:
The following data were obtained from the question:
V1 (initial volume) = 15.0L
P1 (initial pressure) = 2atm
V2 (final volume) = 7.5L
P2 (final pressure) = 4atm
Ki (initial constant) =?
Kf (final constant) =?
Boyle's law states that PV = K
Ki = P1V1
Ki = 2 x 15 = 30atmL
Kf = P2V2
Kf = 4 x 7.5 = 30atmL
Since Ki and Kf are the same, the gas obey Boyle's law
