Answer:
True
Explanation:
Limestone is a carbonate chemical sedimentary rock often chemically called calcium carbonate.
The mineral calcium carbonate makes up the framework of this rock that has become the staple material used for cement production.
Chemically, the formula is given as CaCO₃. The rock accumulates from the a rich deposit of calcite, which is the mineral that is made up of calcium carbonate to form the limestone.
CaCO₃ - Calcite - Limestone
compound mineral rock
Limestone is a rock and the compound it is made up of is calcium carbonate. In some cases, a Ca-Mg carbonate occurs with limestone and it is called a dolomite.
Answer: Sound waves will not be transformed into electrical signals.
Explanation: Just took the test and got a 100!
Answer:
C. 1400
Explanation:
The force exerted = f1 = 250
Diameter d1 = 0.02
r1 = d1/2 = 0.01
Diameter d2 = 0.15
r2 = d2/2 = 0.075
The mass of jack to lift
F1/A1 = f2/A2
250/r1² = f2/r2²
250/0.01² = f2/0.075²
When we cross multiply, we will have:
250x0.005625 = 0.0001f2
1.40625 = 0.0001f2
F2 = 1.40625/0.0001
F2 = 14062.5N
Force f = mg
g = 9.81
m = 14062.5/9.81
Mass = 1433Kg
Therefore option c is correct. A mass of 1400kg can be lifted by the jack
C. The slope of the graph
Explanation:
K in chromatography is defined as a partition coefficient. It is an equilibrium constant that determines the measure to which the solutes partition between two phases.
K = Cm/Cs
where Cm is solute concentration in mobile phase
Cs is solute concentration in stationary phase
When K is more, then it implies that the solute concentration in the mobile phase is more in chromatography test.
