Net Force = Applied Force - Friction
Fnet = (22.8N) - (2.3N)
Fnet = 20.5N
A = change in velocity / change in time
in your case a = 0(final velocity)-30(initial velocity)/10
so, a = -30/10 = -3 m/s^2
I hope this helps you!
metals are conductors, meaning that heat travels through it better than insulators such as plastic (commonly used for pan handles)
Therefore, to avoid the heat burning hands, most pans don't have metal handles.
1: Evaporation, this accounts for the most
2: Transpiration, second most
3: Sublimation, third most
