Answer:
(a) 2800 J
(b) 31.28 %
Explanation:
Heat intake, Q1 = 8950 J
Heat discard, Q2 = 6150 J
(a) Work = intake heat energy - discarded heat energy
W = Q1 - Q2 = 8950 - 6150 = 2800 J
(b) Efficiency = 1 - Q2 / Q1
Efficiency = 1 - (6150 / 8950) = 0.3128 = 31.28%

The answer is C. ionic compounds, compared to another hard compound which is the covalent bond, the structure of the ionic compound is lattice or crystalline in form thus less room for imperfections on its structure compared to the latter choices.
Ick! Word problems! They suck. Okay so first of all you want to narrow it dow the equation.
Step 1. What are the numbers? (In this case 12 m/s and 25 m/s)
Step 2. Are you multiplying, dividing? (In this case your dividing)
Step 3. Divide.
I hope that helps.
