To calculate the energy needed to raise an object, you can use the formula: energy = mass x gravity x height. Plugging in the values, we get: energy = 14 kg x 9.81 m/s^2 x 1 m = 137.34 Joules. So, it takes 137.34 Joules of energy to raise a 14 kg object by 1 meter.

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.
How many joules of energy does a 1 Newton book gain when it is elevated 4 meter?
The gravitational potential energy gained by lifting a 1 Newton book 4 meters is 4 Joules. This is calculated by multiplying the force (1 Newton) by the distance (4 meters) to get the energy in Joules.
How many mega joules per cubic meter of LPG?
The energy content of LPG varies depending on the specific composition of the fuel. On average, LPG has an energy density of around 25-28 megajoules per cubic meter.
How many joules is 10 newtons?
To calculate the energy in joules, we need more information such as the distance over which the force is applied. If we assume the force is applied over a distance of 1 meter, then the work done would be 10 joules (Work = Force x Distance).
How many joules does it take to raise temperature from 30 degrees Celsius to 45 degrees Celsius?
To raise the temperature of a substance, you need to calculate the heat energy using the specific heat capacity of the substance. Without knowing the specific heat capacity of the substance in question, it's not possible to determine the exact amount of energy required to raise the temperature from 30 to 45 degrees Celsius.
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).

A 200 lb man exerts 882 Newtons on earth how many Joules is that if he jumps a meter into the air?
To calculate the work done, we multiply force by distance, so in this case: Work = Force x Distance Work = 882 Newtons x 1 meter = 882 Joules Therefore, the man does 882 Joules of work when he jumps a meter into the air on Earth.
How many joules is 10 newtons?
To calculate the energy in joules, we need more information such as the distance over which the force is applied. If we assume the force is applied over a distance of 1 meter, then the work done would be 10 joules (Work = Force x Distance).

How many calories are present given 50.75 joules of energy?
50.75 joules of energy equates to about 12.1 calories.
How many watts of heat to raise 55.32 gallons of water to 160 degrees?
A watt is a unit of power: what is required is probably the amount of energy - which is measured in joules.
How many joules are in a newton?
There is no direct conversion between joules and newtons because they are units used to measure different quantities. Newtons measure force, while joules measure energy. However, work, which is measured in joules, can be calculated by multiplying force in newtons by distance in meters.
How many joules of energy in a kilo of coal?
On average, 1 kilogram of coal contains approximately 24,000,000 joules of energy.
How many joules are saved by a energy efficient light bulb?
there are 100 joules in an energy efficient light bulb 75 joules go towards the light and 25 joules go towards the heat
