Answer:
51.28 grams of fat will gain
Explanation:
Correction: 10,000 kj about 2500 cal not 2500 kcal.
Asumption: basal metabolic rate will depend of weight, lenght, age and gender but its estipulated a 2000 cal basal metabolic rate as a standar for the calculation for nutritional value of food.
eating a 2500 cal in one day will left
Consuming about 2,500 calories in a day where you only sit relaxed for 16 hours and the rest of the time was used to sleep will mean a basal metabolism of 2000 cal, so 500 calories were left unused, taking into account that 1 calorie is about 4 kj we have to
500 cal * 4kj / cal = 2000 kj
The amount of energy stored as fat will be given by the following equation:
Unused energy / energy contained in one gram of fat = 2000 kj / (39 kj / g) = 51.28 grams of fat gain
Answer:
a direct current goes in one direction at all times whereas an alternating current goes back and forth in a circuit
Answer: Heat is produced
Explanation:
From the law of conservation of energy and mass, these cannot be created nor destroyed but can convert from one form to another. When fuel is burnt, heat is produced which changes into mechanical energy ( potential energy + kinetic energy). Thus, chemical energy of the fuel transforms to heat energy which transforms to mechanical energy. This shows that energy transformation has taken place.
