Which equation shows the relationship of wave speed to wavelength and wave frequency?
a Speed = Wavelength x Frequency
b Speed = Wavelength/Frequency
C Speed = Frequency/Wavelength
d None of the above

Use the empirical rule. the mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 4 miles per hour. estimate the percent of vehicles whose speeds are between 66 miles per hour and 74 miles per hour. (assume the data set has a bell-shaped distribution.)

If a sphere and a cure have the same mass and are propelled up a ramp with the same force, which would travel father up the ramp? explain.
