The number of kilojoules needed in a day varies depending on factors like age, gender, weight, activity level, and goals. On average, most adults need between 8,700 to 10,500 kilojoules (2,000 to 2,500 calories) per day to maintain their weight and energy levels. It's best to consult with a healthcare provider or a dietitian to determine a more accurate and personalized daily kilojoule requirement.

How much electrical energy in joules does a nuclear power reactor generate in one day?

The amount of electrical energy generated by a nuclear power reactor in one day can vary depending on its capacity and efficiency. However, a typical nuclear power reactor can generate around 1-2 billion joules of electrical energy per day.


How much energy does a person need in a day in joules?

On average, an adult requires about 8,700,000 joules (8.7 megajoules) of energy per day to maintain bodily functions, perform daily tasks, and engage in physical activity. This is equivalent to approximately 2,000 kilocalories (kcal) or calories.


How many kilo joules does a 12 year old boy need?

A 12-year-old boy typically needs around 1,800-2,400 kilocalories per day to support growth and development. This is equivalent to approximately 7,500-10,000 kilojoules. The exact amount can vary based on factors like activity level, metabolism, and overall health.


A couch potato might consume 6 million Joules of energy in a day What is this rate of energy consumption in watts?

To convert energy consumption from Joules to watts, divide by the number of seconds in a day (86,400). The rate of energy consumption for the couch potato would be 69.4 watts.


How many joules of Solar energy in 1 sq meter?

On average, the amount of solar energy hitting 1 square meter of the Earth's surface is about 1000 watts, or 1000 joules per second under full sun exposure. This can vary depending on factors such as location, time of day, and atmospheric conditions. So, in one hour (3600 seconds), 1 square meter would receive about 3.6 million joules of solar energy under those conditions.
