How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
How many calories of energy per gram does the body supply fat?
9 calories of energy per gram. 9 calories of energy per gram.
Why does drinking milk supply your body with energy but water does not?
Milk contains calories which give you energy. Water doesn't contain calories.
How many calories of energy do proteins supply the body with per gram?
4
How much thermal energy is required to boil 2.83 kg of water from 50c?
2830 g of water raised through 50 degrees C would use 2830 x 50 calories. But then to boil the water away to steam completely requires another 550 calories per gram, which is 2830 x 550 calories. To convert to Joules, use 4.2 Joules per calorie.
What do vitamins not supply like fats carbohydrates and protein do?
Vitamins do not provide energy or calories.
A human heart consumes about 1 joule per heartbeat about how many joules of energy must food furnish to a person each day to supply this energy?
The energy required is roughly 3600 seconds/hour x24 hours/day x1 joule/second=86400 joules /day.
How many joules of energy is consumed if the electrical meter shows 400 units of energy?
To determine the joules of energy consumed, you would need to know the conversion factor from the units displayed on the electrical meter to joules. This conversion factor varies depending on factors like the voltage and current of the electricity supply. Typically, 1 unit of energy is equivalent to approximately 3600 joules. So if the meter reads 400 units, the energy consumed would be around 1,440,000 joules (400 units * 3600 joules/unit).
What kind of electricity supply is used for electrolysis?
It must be direct current for electrolysis.
The nutrient that provides the greatest amount of energy per gram is?
In food, there are three macronutrients that provide energy. They are fat, carbohydrates, and protein. Fat is the nutrient that provides the greatest amount of energy at nine calories per gram. Protein and carbohydrates provide only four calories per gram.
Which of the following nutrient does not supply calories to the body?
Water does not supply calories to the/our body.............
What biomolecules in your lunch will supply the most energy per gram?
Fats generally supply the most energy per gram in our diet. They provide 9 calories per gram, while carbohydrates and proteins provide 4 calories per gram. In your lunch, foods high in fats such as nuts, seeds, avocado, or fatty fish would supply the most energy per gram.
