A stationary source S generates circular outgoing waves on a lake. Thewave speed is 5.0 m/s and the crest-to-crest distance is 2.0 m. A personin a motor boat heads directly toward S at 3.0 m/s. To this person, thefrequency of these waves is:

Transfer chemicals from one location to another to weather objects. a-water b-physical weathering c-chemical weathering

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.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
