the equation of a plane progressive wave is y= 2×10^-4 sin(100t-50x) then the velocity of the wave is ?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

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