I googled the specific heat capacity for iron so it might be off to the value you might have used, bit it should be close.
Answer:
0.315
Explanation:
resolving weight into components and applying second law of motion we obtain the result
All has been explained in attachment
<span>if we take ball then the Kinetic Energy of the ball is ½mV²
as it rolls up the slope, the Kinetic Energy is converted to potential energy, PE = mgh.
mgh = ½mV²
h = V²/2g</span>
The primary method of heat transfer when ironing clothes is conduction. The iron heats up very quickly because it is metal, which is a good conductor.
