If the calculated Rf value is .59, what pigment is separated?
If two pigments were separated through chromatography and were found to have Rf value of .43 and .80, which pigment the greatest molecular weight?
If two pigments were separated through chromatography and were found to have Rf values of .67 and .39, which pigment traveled the farthest?
##R.= 6##, ##C. ~~ 38## and ##A. ~~ 113##.
First you need to find the radius, the key term to find the radius is ##diameter = 2*radius##; therefore the radius ##r## is ##12/2 = 6## inches.
To find the area of a circle, you need to use the formula ##A = pi*r^2##; therefore the area ##A## is ##pi*6^2 ~~ 113## square inches.
To find the circumference of a circle, you will use the formula ##C = 2*pi*r##; therefore the circumference ##C## is ##2*pi*6 ~~ 38## inches.
If the desired capital stock is $20,000, the current level of the capital stock is $12,000, and a firm wishes to close half of the gap between them each period, what does the flexible accelerator model suggest will be next period’s level of investment? What will be the level of investment the year after that?
If the demand curve for wheat in the United States is P=12.4-Qd where P is the farm price of wheat(in dollars per bushel) and Qd is the quantity of wheat demanded(in billions of bushels), and the supply curve for wheat is the United States is P=-2.6+2Qs where Qs is the quantity of wheat supplied(in billions of bushels), what is the equilibrium price of wheat? What is the equilibrium quantity of wheat sold? Must the actual price equal the equilibrium price? Why or why not?
Answer:Demand curve for wheat in the United States is P=12.4-Qd and the supply curve for the wheatin the United States is P=-2.6+2Qs where P=Price, Qd =Quantity demanded, Qs=QuantitysuppliedNow…
If the current is recorded as being greater than it actually is, would Avogadro’s number be calculated too high, too low, or be unaffected? Explain.Repeat the calculation of Avogadro’s number, using the mass gain of the cathode instead of the mass loss of the anode. Account for any Difference in the calculated value.
If the external world does work in a system, the ______.a) amount of work done on the system has a negative valueB) energy of the system decreasesc) energy of the system increasesD) external world becomes warmer
If the current in a wire of a CD player is 4.30mA, how long would it take for 13.0 C ofcharge to pass a point in this wire?
If the expected total return return of a stock is 14%, the dividend yield is 3%, and the
current price is $40. The market risk premium is 7% and risk free rate is 5%, assume the
stock is in equilibrium.
A. What is the expected one year future price? 2pts. Show all work.
.14 = .03 + (P1 – $40/$40)
.11 = p1 – $40 / $40
P1 = $44.40
