<span>The heat energy is being transferred between the two substances by thermal conduction. Because the hot coffee is at a different temperature to the mug, heat energy flows between them so that they reach thermal equilibrium, or the same temperature. This kind of heat transfer always happens from hotter temperatures to cooler temperatures.</span>
Answer:
energy:
-the strength and vitality required for sustained physical or mental activity.

Explanation:
Answer:
<h2> 27m/s</h2>
Explanation:
Given data
initital velocity u=15m/s
deceleration a=3m/s^2
time t= 4 seconds
final velocity v= ?
Applying the expression
v=u+at------1
substituting our data into the expression we have
v=15+3*4
v=15+12
v=27m/s
The velocity after 4 seconds is 27m/s
