Answer:

4. 7.59276

Explanation:

Add up the x components:

Aₓ + Bₓ + Cₓ = 5 − 1.6 + 2.4 = 5.8

Add up the y components:

Aᵧ + Bᵧ + Cᵧ = -2.4 + 3.3 + 4 = 4.9

Use Pythagorean theorem to find the magnitude:

√(x² + y²)

√(5.8² + 4.9²)

√57.65

Complete Question

The complete question is shown on the first uploaded image

Answer:

The <u>Fruit juice </u> should be put in the cooler, because <u>it has the greatest heat capacity</u> and will therefore, <u>absorb the most heat for each degree it increases in temperature.</u>

Explanation:

in order to understand the answer above we need to know what specific heat capacity is

       Specific heat capacity  can be defined as the amount of heat required to raise the temperature of a unit mass of a substance by one degree  

     Looking at the specific heat of each substance suggested we see that the fruit juice has a higher specific heat capacity than others this is because it contains a higher amount of water , generally liquid states of substances have a higher specific heat capacity than other states. The specific heat capacity of fruit juice being the highest among the suggested substances means that it can absorb  more heat for each degree temperature of refrigerator.
