How do you find how much energy is transferred in an hour joules?
To find out how much energy is transferred in an hour in joules, you need to know the power consumption of the device in watts. You can calculate the energy transferred by multiplying the power in watts by the time in hours. The formula is Energy (joules) = Power (watts) x Time (seconds).
How much energy is needed to melt 2kg of gold?
It takes approximately 64,000 Joules of energy to melt 1kg of gold. Therefore, to melt 2kg of gold, you would need around 128,000 Joules of energy.
What is 75kg in joules?
Mass is measured in kilograms, not in joules. Joules are a unit of energy. To calculate the energy of a 75kg mass, you would need additional information such as the velocity or height it is at.
How much power is a 150 joules?
Power is the rate at which energy is transferred or converted. To determine the power in watts from joules, you need to know the time taken for the energy transfer. If the energy transfer of 150 joules occurs in 3 seconds, the power would be 50 watts (150 joules / 3 seconds = 50 watts).
How much mechanical energy will be provided by a motor that is 70 percent efficient and requires 1960 joules of energy?
To calculate the mechanical energy provided by the motor, you need to divide the input energy by the efficiency of the motor. In this case, with 70% efficiency, you would divide 1960 joules by 0.70 to find that the mechanical energy provided would be approximately 2800 joules.

How do you calculate how much energy a battery has with only the volts and coulombs?
To calculate the energy stored in a battery with volts and coulombs, you can use the formula: Energy (Joules) = Voltage (Volts) x Charge (Coulombs). Multiply the voltage by the charge of the battery to get the energy capacity in Joules.

How much is 4180J in kw?
To convert joules to kilowatts, you need to divide the energy in joules by 3,600,000 (since 1 kWh = 3,600,000 J). Therefore, 4180 J is 0.00116 kWh.
What does the word joules have to do with chemistry?
Joules are a measurement of energy. This has to do with chemistry because scientists and chemists need to be able to measure energy in chemistry experiment, and this is an accurate measurement.
Is it true that energy is measured in joules?
Yes, but it might be confusing to some, because it is also the unit for work. To do 100 joules of work, you need 100 joules of energy. See related link for more detail.
What is joules to the decimal place?
Oh, dude, joules is just a unit of energy, like how much effort it takes to lift a donut to your mouth. To the decimal place? That's like getting super precise about how much energy you need to eat that donut. Just think of it as a tiny amount of energy, like when you decide to get up from the couch to grab another snack.
How do you convert Joules per sq cm to Joules?
To convert from Joules per square centimeter (J/cm^2) to Joules (J), you would need to multiply the value in J/cm^2 by the area over which the energy is distributed in square centimeters. This will give you the total energy in Joules.
How much voltage is 6 joules?
Voltage cannot be directly converted from joules, as they are different units of measurement. Joules represent energy, while voltage is a measure of electric potential difference. To determine voltage, you would need more information such as current and resistance in the circuit.
