A battery uses 810J of energy to run a portable radio for 30 minutes What is the power of the radio?
810 joules / 30 minutes = 810 joules / 1,800 seconds = 0.45 joule per second = 0.45 watt.By the way:-- The battery supplies the energy at the rate of 0.45 watt.-- The radio uses or consumes the energy at the rate of 0.45 watt.
How many joules are in a refrigerator?
For every joule of electricity we put into a refrigerator we can extract up to 25 joules of heat from its contents.
Why don't you use joules as the unit for electricity bills?
because we dont tuxford
Which wave has more energy out of microwaves radio waves infrared waves and visible light waves?
The radio spectrum for communications spans approximately from 150 kHz to 26 MHz. The visible light frequency range is at least 400 THz. No contest -- visible light is at least 15 million times higher in frequency. Energy = Planck's constant * frequency. Hence visible light carries a higher energy.
How do you reheat egg foo young or not?
put it in a metal pot fill it with water and then heat it up. since it takes 4.19 joules to heat up water by 1C the egg will also be hot.
What is the unite of energy?
the energy unit is called joules
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 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.
What is the conversion from joules of energy to watts of energy?
Power (watts) is a measure of energy transfer over time, while energy (joules) is a measure of total work done. The formula to convert energy in joules to power in watts is: Power (watts) = Energy (joules) / time (seconds).
What type of energy is measured in joules?
All types of energy may be measured in Joules.
What quantity has units of joules?
Energy has units of joules.
What can be measured in joules?
Various forms of energy can be measured in joules, such as kinetic energy, potential energy, heat energy, and electrical energy. Joules are a unit of measurement for energy and can be used to quantify the amount of energy present in a system or the amount of work done.
100 joules of heat plus to system of 60 joules of work?
The total energy added to the system is 160 Joules, comprising of 100 Joules of heat and 60 Joules of work. This increase in energy will lead to a rise in the system's internal energy.
How many calories are present given 50.75 joules of energy?
50.75 joules of energy equates to about 12.1 calories.
What is the Unit of measurement for electromagnetic energy?
The unit of measurement for electromagnetic energy is the joule (J).
How much heat energy is produced from 3000 joules of electrical energy?
The amount of heat energy produced from electrical energy depends on the efficiency of the system. If we assume 100% efficiency, then all 3000 joules of electrical energy would be converted into heat energy. Thus, 3000 joules of electrical energy would produce 3000 joules of heat energy.
