Day and night is due to the earth rotating. Seasons are due to the earth rotating on a slightly tilted axis, causing light to be shone on different parts of the earth more directly during different parts of the year. Constellations changing throughout the night are because of the earth moving and rotating. Throughout the year, the earth moves, causing us to be facing different directions in different parts of the year. The North Star does't move because it is close to Earth's line of axis, and therefore does not appear to move.

A large hamburger sandwich contains 628 kcal and 36 grams of fat. Approximately what percentage of the total energy is contribut
Klio2033 [76]

The percentage of the total energy contributed by fat = 51.59% of fat

<h3>Calculation of total energy in fat</h3>

The quantity of fat in the hamburger = 36grams

But 1 gram of fat = 9 kcal( standard energy value per gram of fat).

That is , 9kcal = 1 gram

X kcal = 36 grams

cross multiply,

X kcal = 9 × 36

= 324kcal

To calculate the percentage of 324kcal of fat in 628 kcal,

\% =  \frac{324}{628}  \times  \frac{100}{1}

\% =  \frac{32400}{628}

% = 51.59% of fat

The percentage of the total energy contributed by fat = 51.59%
