Explain how will each of the following changes in demand and/or supply affect equilibrium price and equilibrium quantity in a competitive market; that is do price and quantity rise, fall, remain unchanged, or are the answers indeterminate because they depend on the magnitudes of the shifts? Use supply and demand diagrams to verify your answers. a. Demand increases and supply is constant.
b. Supply increases and demand decreases.
c. Demand increases and supply decreases.
d. Demand decreases and supply decreases.

a. If demand increases and supply is constant, there would be a rightward shift of the demand curve. As a result, equilibrium price and quantity would increase

b. An increase in supply would lead to a rightward shift of the supply curve. As a result price decreases and quantity increases. A decrease in demand would lead to a leftward shift of the demand curve. As a result, quantity and price decreases.  Taking these two effects together, equilibrium price decreases and there is an indeterminate effect on equilibrium quantity

c. An increase in demand leads to a rightward shift of the demand curve. As a result, equilibrium price and quantity increases. A decrease in supply would lead to a leftward shift of the supply curve. This leads to a decrease in quantity and an increase in price. Taking these two effect together, there would be an increase in equilibrium price and an indeterminate effect on equilibrium quantity

d.  A decrease in demand would lead to a leftward shift of the demand curve. As a result, quantity and price decreases.  A decrease in supply would lead to a leftward shift of the supply curve. This leads to a decrease in quantity and an increase in price. Taking these two effect together, there would be a decrease in equilibrium quantity and an indeterminate effect on equilibrium price

among other factors, composers started writing dynamic markings in their scores because "new instruments allowed for more dynamic ranges and contrast."

dynamics allude to the loudness or softness of music. dynamics offer an approach to demonstrate articulation in sheet music. they to drive the enthusiastic substance of music through volume and force. maybe you could alter both the volume and the shading profundity on your screen at the same time. we can likewise think about the force side of elements as the quality of a note. a few notes are intended to be played delicately and gently, while others are intended to be played all the more firmly.  

some dynamics markings have a letter 'm,' which remains for mezzo, signifying 'medium.' so a mezzo piano unique stamping resembles this (mp) and intends to play medium calm, while a mezzo specialty dynamic resembles this (mf) and intends to play medium loud.
