A 2kg energy drink is placed inside a -20oC freezer to cool it off. What is the mass of the air needed in order to cool the energy drink from 25oC down to 17oC? Assume the refrigerator is a perfect insulator. The specific heat capacity of the energy drink is 4184 J/kgoC. The specific heat capacity of the air is 1000 J/kgoC.

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

2 over 5 and 4 over 15

don’t know last one sorry
