Answer:
<h3>The answer is option A</h3>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question

Focus your attention to the units of the given data and the unit of the final measurement you're going to solve. Through dimensional analysis,you know that the working equation would be:
Food Value = CcalΔT/m
Food value = (6.15 kJ/°C)(1.29 °C)/0.611 g = 12.98 kJ/g
Convert kJ to cal (1 kJ = 239 cal)
Food value = 12.98*239 =<em> 3,103.28 cal/g</em>
