The nose of an ultralight plane is pointed south, and its airspeed indicator shows 38 m/s . The plane is in a 11 m/s wind blowing toward the southwest relative to the earth.

a- Letting x be east and y be north, find the components of v? P/E (the velocity of the plane relative to the earth).

b- Find the magnitude of v? P/E.

c- Find the direction of v? P/E.

Waves are used in many practical applications to support work, entertainment, and health. one example is the use of ultrasound imaging to safely track the development of a growing fetus. what is a specific example of a practical application of waves in medicine, entertainment, safety, or other fields? provide a brief explanation of how the properties of waves are useful to that application.

Suppose you plot the distance traveled by an object at various times and you discover that the graph is not a straight line. what does this indicate about the object's acceleration?
