Convert the following numbers of calories or

kap26 [50]

Answer:

32.823 kJ
190.4 kJ
260.00 kJ
180.012 kJ

Step-by-step explanation:

The conversion factor for food energy or thermochemical calorimetry* is ...

1 calorie = 4.184 J

1000 calorie = 4.184 kJ

a. 7845 cal = 7845·4.184 J = 32,823 J = 32.823 kJ

b. 4.55·10^4 cal = 4.55·10^4·4.184 J = 1.904·10^5 J = 190.4 kJ

c. 62.142 kcal = 62.142·4.184 kJ = 260.00 kJ

d. 43,024 cal = 43,024·4.184 J = 180,012 J = 180.012 kJ

_____

* The thermochemical calorie is defined in terms of the heat capacity of water. An international calorie of 4.1868 J is defined in terms of energy, without respect to the heat capacity of water.

A standard baseball diamond is a square with 90-foot sides and a base at each corner. To the nearest foot, what is the greatest

solong [7]

The longest distance would be from two opposite bases. For example, if we were to connect home plate with 2nd base, the line between the two bases would be longer than the distance between home and 1st. This is because in a right triangle, the hypotenuse is always the longest side.

We can use Pythagorean Theorem to find the distance.

$a^2 + b^2 = c^2$

$90^2+90^2 = c^2$

$c^2 = 16200$

$c= \sqrt{16200}$

$c = 127.28 feet$

To the nearest foot, the answer is 127 feet.
