Aduck floating on a lake oscillates up and down
5.0 times during a 10.-second interval as a
periodic wave passes by. what is the frequency
of the duck’s oscillations?
(1) 0.10 hz (3) 2.0 hz
(2) 0.50 hz (4) 50. hz
what formula do i use for this? (in accordance with the nys physics reference table)
the answer is 2

The consumption of fossil fuels could be

Which accounts for an increase in the temperature of a gas that is kept a constant volume
