Peacock mantis shrimps (odontodactylus scyllarus) feed largely on snails. they shatter the shells of their prey by delivering a sharp blow with their front legs, which have been observed to reach peak speeds of 23 m/s. what is this speed in feet per second?

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.)

When an object is heated it contracts. a. true b. false

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.
