Their "airspeeds" (speed through the air) are equal, but the one traveling in the
same direction as the jet-stream appears to move along the ground faster.
Explanation:
The power P dissipated by a heater is defined as

where V is the voltage and I is the current.
a) The current running through a 130-W heater is

b) The resistance <em>R</em><em> </em>of the heater is

where
is our familiar Ohm's Law.
