Energy that is not utilized for work or heat transfer is converted to the chemical energy of body fat containing about 39 kj/g. how many grams of fat will you gain if you eat 10,000 kj (about 2500 kcal) one day and do nothing but sit relaxed for 16.0 h and sleep for the other 8.00 h

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

mass=238.52g

Explanation:

Energy that is not utilized for work or heat transfer is converted to the chemical energy of body fat containing about 39 kJ/g. How many grams of fat will you gain if you eat 10,000 kJ (about 2500 kcal) one day and do nothing but sit relaxed for 16.0 h and sleep for the other 8.00 h

unutilized energy converted to body fat, F=39 kj/g

time to relax=16h

consumed energy =10000 kj

sleeping time=8h

rate of energy consumption whilst sleeping=83j/s

rate of energy consumption whilst sitting=120j/s

energy is power x time

E=p*t

substituting the parameters

energy used in sleeping=83j/s*8*3600=2390400=2390.4kJ

energy consumed whilst sitting=120j/s*16*3600=6912kj

total unused nery =2390.4kJ+6912kj

9302.4kj

energy stored /mass=39 kJ/g

9302.4kj=39 kJ/g*mass

mass=9302.4kj/39 kJ/g

mass=238.52g

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
