Context: Marino finished the game with 29 out of 50 pass completions for 318 yards, 1 touchdown, and 2 interceptions. Clayton was the top receiver of the game, with 6 receptions for 92 yards. Walker returned 4 kickoffs for 93 yards and gained 15 yards on 2 punt returns. Nathan was the Dolphins leading rusher with 18 yards, while also catching 10 passes for 83 yards. Craig had 58 rushing yards, 77 receiving yards, and 3 touchdowns. He was the first player ever to score 3 touchdowns in a Super Bowl, and his 2 touchdown catches also tied a Super Bowl record. Tyler led San Francisco in rushing with 65 yards, and also caught 4 passes for 70 yards. Clark caught 6 passes for 77 yards. Board recorded 2 sacks. McLemore recorded 51 punt return yards, the second most in Super Bowl history. Sports Illustrated called 49ers defensive tackle Gary Johnson (American football) the Super Bowls "unofficial defensive MVP" after he recorded one sack, flushed Marino out of the passing pocket numerous times, and had four unassisted tackles.
Question: Who had a higher average of yards per caught pass, Clayton or Clark?
clayton

Context: Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed (and speed in general) can be represented by the equation: Speed = Distance Time Wave speed is related to both wavelength and wave frequency. Wavelength is the distance between two correspond- ing points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. This equation shows how the three factors are related: Speed = Wavelength x Wave Frequency In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed. Q: If you increase the wavelength of a wave, does the speed of the wave increase as well? A: Increasing the wavelength of a wave doesnt change its speed. Thats because when wavelength increases, wave frequency decreases. As a result, the product of wavelength and wave frequency is still the same speed. Click image to the left or use the URL below. URL: The equation for wave speed can be used to calculate the speed of a wave when both wavelength and wave frequency are known. Consider an ocean wave with a wavelength of 3 meters and a frequency of 1 hertz. The speed of the wave is: Speed = 3 m x 1 wave/s = 3 m/s Q: Kim made a wave in a spring by pushing and pulling on one end. The wavelength is 0.1 m, and the wave frequency is 2 hertz. What is the speed of the wave? A: Substitute these values into the equation for speed: Speed = 0.1 m x 2 waves/s = 0.2 m/s The equation for wave speed (above) can be rewritten as: Frequency = Speed Wavelength or Wavelength = Speed Frequency Therefore, if you know the speed of a wave and either the wavelength or wave frequency, you can calculate the missing value. For example, suppose that a wave is traveling at a speed of 2 meters per second and has a wavelength of 1 meter. Then the frequency of the wave is: Frequency = 2m/s 1m = 2 waves/s, or 2 Hz Q: A wave is traveling at a speed of 2 m/s and has a frequency of 2 Hz. What is its wavelength? A: Substitute these values into the equation for wavelength: Wavelength = 2m/s 2waves/s =1m The speed of most waves depends on the medium, or the matter through which the waves are traveling. Generally, waves travel fastest through solids and slowest through gases. Thats because particles are closest together in solids and farthest apart in gases. When particles are farther apart, it takes longer for the energy of the disturbance to pass from particle to particle through the medium. Click image to the left or use the URL below. URL:
