A) Single replacement; zinc chloride and hydrogen gas
Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning).
Change in speed = (10 m/s) - (zero) = 10 m/s
Time for the change = 3 sec
Acceleration = (10 m/s) / (3 sec)
<em>Acceleration = (3 and 1/3) m/s²</em> or 3.333 m/s²
Air is cooled and
becomes denser.
Denser air sinks.
The process repeats, producing a (i wasn't sure about this one)
Air is heated and becomes less dense.
Less dense air rises.
hope this helps!
