A pin fin of uniform, cross-sectional area is fabricated of an aluminum alloy $(k = 160 \frac{W}{m} \cdot K)$ . The fin diameter is $D = 4$ mm, and the fin is exposed to convective conditions characterized by $h = 220 \frac{W}{m^{2}} \cdot K$ . It is reported that the fin efficiency is $η_{f} = 0.65$ . Determine the fin length L and the fin effectiveness $ε_{f}$ Account for tip convection.

A dockworker applies a constant horizontal force of 80.0 N to a block of ice on a smooth horizontal floor. The frictional force is negligible. The block starts from rest and moves 11.0 m in 5.00 s.
1) What is the mass of the block of ice?
2) If the worker stops pushing at the end of 5.00 s, how far does the block move in the next 5.00 s?

Contrary to a popular belief, equation in math also contains things like inequalities and expressions that require logic and verbal explanations. This is where equation help becomes useful as you look at the answers below. See equation problems submitted by students like you and explore the answers. It will help you to understand the logic as you approach equation algebra and study expressions examples. These are not as complex as they may seem once you learn how to connect expressions and equations and understand them as a finite combination of symbols, depending on use.
