Lila is a track and field athlete. She must complete four laps around a circular track. The track itself is a 400 meter track and it took her 6 minutes total to complete. Which best describes her speed and velocity? (There are 60 seconds in 1 minute.) A. Her speed is 4.4 m/s, and her velocity is 0 m/s. B. Her speed is 1.1 m/s, and her velocity is 0 m/s. C. Her speed is 0 m/s, and her velocity is 2400 m/s. D. Her speed is 4.4 m/s, and her velocity is 4.4 m/s.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

Which lists the pairs of plates in order from least to greatest in terms of the work done to move the electron?
