Aspring is stretched to a length of 5.40 m. you generate a standing wave using a frequency of 4.75 hz. if there are 5 antinodes along the spring, then the speed of the wave in the spring is m/s. (record your
three-digit answer on the answer sheet.)

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.

Another word for electromagnetic energy is a. heat b. force c. matter d. radiation
