Suppose the government imposes a 20-cent tax on the sellers of artificially sweetened beverages. the tax would shift

a)demand, raising both equilibrium price and quantity in the market for artificially sweetened beverages.

b)demand, lowering the equilibrium price and raising equilibrium quantity in the market for artificially sweetened beverages

c)supply, raising the equilibrium price and lowering the equilibrium quantity in the market for artificially sweetened beverages.

d)supply, lowering the equilibrium price and raising the equilibrium quantity in the market for artificially sweetened beverages.

Suppose the market for widgets can be described by the following equations:

Demand: P = 14 1.00Q
Supply: P = 1.00Q + 6,

Where P is the price in dollars per unit and Q is the quantity in thousands of units. What are the equilibrium price and quantity? The equilibrium quantity is ______ units and the equilibrium price is $______.

Suppose the government imposes a tax of $1 per unit to reduce widget consumption and raise government revenues. What will be the new equilibrium quantity? What price will the buyer pay? What amount will the seller receive?

The new equilibrium quantity will be __________.
The price paid by buyers will be $__________.
The amount kept by sellers will be $__________.

Suppose the market for farm machinery in Canada can be represented by the following equations:-

                  Q^d = 300,000  - 10 P  

                  Q^s =  50,000  + (5/2) P

where Q^d and Q^s are, respectively, the quantity demanded and quantity supplied of farm machines per year and  P  is price of each machine (in dollars). Suppose the government imposes a $1,000 per unit tax on the purchasers.  The incidence of the tax can be described by:

Who invented the zero number?

Briefly explain ONE example of how American society remained the same, despite the changes brought by the new technology or development.

Sulfur dioxide is produced in enormous amounts for sulfuric acid production. It metls at -73.0 degrees Celsius and boils at -10.0 degrees celsius. Its change enthalpy (fusion) is 8.619 kJ/mol, and its change in enthalpy (vaporization) is 25.73 kJ/mol. The specific heat capacities of the liquid and gas are 0.995 J/g.K and 0.622J/g.K, respectively. How much heat is required to convert 2.750kg of solid SO2 at the metling point to a gas at 60.0 degrees Celsius?

Calculate the heat required in Joules to convert 18.0 grams of ice at a temperature of -20.0° C to liquid water at 75^oC.   

Given:
-specific heat of ice = 2.06 J/g°C
-specific heat of liquid water = 4.184 J/g°C
-specific heat of water vapor = 2.02 J/g°C
-heat of fusion of water = 334 J/gram
-heat of vaporization of water = 2260 J/gram
