Courtney kicks a soccer ball that is at rest on level ground and gives it an initial velocity of 7.8 m/s at an angle of 32° above the ground. Assume that forces due to air drag on the ball are insignificant. a. How long will the ball be in the air? b. How high will the ball go? c. What will be its range? Sketch And Analyze The Problem Sketch the situation. List the knowns and unknowns. ​

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

Apropagating wave in space with electric and magnetic components. these components oscillate at right angles to each other. it may travel in a vacuum. determine the term.
