Miguel owns a taco shop in a city in which there are many other taco shops. There are no barriers to entry. Miguel can charge a higher price for his food because he uses a special sauce recipe passed down to him from his grandmother. Miguel stays in the taco business because he makes the same profit he would make if he devoted his resources to his next best option. What aspect of Miguel's business indicates that he is not in a perfectly competitive industry?

answerconversion factor;

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.
