1 Joule = 1 Watt.sec, ie 1 Watt for 1 second. A 75 Watt bulb dissipates 75 Joules every second, so the answer is 10/75 of a second = 0.1333 seconds

To calculate the time required, you can use the formula Energy = Power x Time. Rearranging the formula gives Time = Energy / Power. Plugging in the values, Time = 10 Joules / 75 Watts = 0.133 seconds. So, it would take approximately 0.133 seconds for a 75-watt light bulb to dissipate 10 joules of energy.

How much energy is required to melt 10g of ice?
The energy required to melt ice is known as the heat of fusion, which is about 334 joules per gram. Therefore, it would take approximately 3340 joules of energy to melt 10g of ice.
How much energy must be absorbed by 150 grams of ice?
To get ice to its melting point, it must absorb 334 joules of energy per gram of ice. So, for 150 grams of ice, the total energy required would be 50,100 joules (334 J/g * 150 g).
How many joules of light energy are in 1440 watts of electrical energy?
To calculate the energy in joules, you can use the formula: energy (joules) = power (watts) × time (seconds). If you have 1440 watts of electrical power and want to calculate the energy in joules for a specific time period, you would need to know the time duration in seconds.
What contains the most joules of energy a banana or a sausage?
1 calorie is equal to 4.186 joules. sausage is 50 calories or 209.3 joules of energy. banana is 105 calories or 439.53 joules of energy. Therefore a peeled banana contains much more joules of energy than tasty looking sausages. ;)
How many joules would be required to heat 0.5kg of aluminum?
The specific heat capacity of aluminum is 0.897 J/g°C. To calculate the energy required to heat 0.5kg of aluminum by a certain temperature change, you would use the formula: Energy = mass x specific heat capacity x temperature change If you have the temperature change, you can plug the values into the formula to find the total energy in joules.
Is 1044 joules a lot of energy?
1044 joules is not considered a lot of energy in most contexts. For example, it is equivalent to the energy required to lift a small apple a few feet off the ground. In comparison to larger energy units like kilowatt-hours, 1044 joules is relatively small.
How much energy is required to melt 2kg of gold?
To melt 2 kg of gold, it would require approximately 66,190 Joules per gram. Therefore, for 2 kg of gold, the total energy required would be around 132,380,000 Joules.
The specific heat of gold is 0.131 Joules per gram. Celsius How much energy is required to heat 1.3 grams of gold from 25 Celsius to 46 Celsius?
The change in temperature is 21 degrees Celsius. To calculate the energy required, we use the formula: Energy = mass * specific heat * change in temperature. Plugging in the values, Energy = 1.3g * 0.131 J/g°C * 21°C = 35.247 Joules. Therefore, 35.247 Joules of energy is required to heat 1.3 grams of gold from 25°C to 46°C.
How do you get joules with only distance and weight?
To calculate the amount of energy (joules) required to lift an object, you can use the formula: Energy (joules) = Weight (Newtons) x Distance (meters) x gravitational constant (9.81 m/s^2). Simply multiply the weight of the object by the distance it is lifted and the value of gravity to determine the total energy in joules.
What is the unite of energy?
the energy unit is called joules
How much energy in joules is required to move a charge 6C through a difference in potential of 3V?
q=6C V=3V U=qV=(6C)(3V)=18 J U(potential energy)=18 Joules (18J)
What does the latent heat of fusion measured?

What is the metric unit for measuring energy?
Joules are the metric units used to measure energy. When you are working with any form of energy you state them in joules.
What is the difference between btus and joules?
BTUs (British Thermal Units) and joules are both units of energy measurement. The main difference is that BTUs are commonly used in the United States and joules are used in the International System of Units (SI). One BTU is approximately equal to 1055 joules.
What is the unit of measuring kinetic energy?
Joules, all energy is measured in joules.
What is kinetic's energy unit of measure?
Joules, all energy is measured in joules.
How much joules of energy is present in 1 kg of water?
The amount of energy present in 1 kg of water is typically around 4,186,000 joules at room temperature. This value represents the energy required to raise the temperature of 1 kg of water by 1 degree Celsius.
