In what way is power related to energy?
Power is related to energy in that power is the rate at which energy is transferred or converted. In other words, power measures how quickly energy is used or produced.
What does the voltmeter measure when it is across the cell?
When a voltmeter is connected across a cell, it measures the potential difference, or voltage, between the two terminals of the cell. This reading indicates the electromotive force (emf) generated by the cell, which is a measure of the cell's ability to provide electrical energy to a circuit.
What is the device used to measure electrical potential energy?
A voltmeter is typically used to measure electrical potential energy. It is connected in parallel with the component or circuit being measured to determine the voltage difference or potential between two points.
Which correctly describes what power measures?
Power measures the rate at which work is done or energy is transferred. It is the amount of energy transferred or converted per unit of time. In physics, power is typically measured in watts.
What are 20 examples of energy conversion?
Chemical energy in food is converted to mechanical energy when our muscles move. Solar energy is converted to electrical energy in solar panels. Electrical energy is converted to light and heat energy in an incandescent light bulb. Wind energy is converted to electrical energy in wind turbines. Potential energy in a dam is converted to electrical energy in a hydroelectric power plant. Thermal energy in fossil fuels is converted to electrical energy in a power plant. Nuclear energy is converted to electrical energy in nuclear power plants. Mechanical energy in a car engine is converted to kinetic energy to move the car. The kinetic energy of falling water is converted to mechanical energy in a waterwheel. Sound energy is converted to electrical energy in a microphone. Electric energy is converted to sound in a speaker. Kinetic energy in moving air is converted to electrical energy in a wind turbine. Chemical energy in batteries is converted to electrical energy in electronic devices. Gravitational potential energy is converted to kinetic energy when an object falls.

What instrument used to measure the energy converted per unit charge?
A voltmeter.
What does a Voltmeter do in a circuit?
A voltmeter measures the voltage present in the circut. Voltage is the amount of energy available to push charges through an electric circut.

How is the term 'matter' defined in science?
In science, 'matter' is the basic structural component of the universe that possesses inertia and volume and that can be converted into energy.

What kind of energy is coverted when you burn gasoline?
Chemical energy is converted into heat energy.Chemical energy is converted into heat energy.Chemical energy is converted into heat energy.Chemical energy is converted into heat energy.
As a rocket rises its kinetic energy changes. At the time the rocket reaches its highest point most of the kinetic energy of the rocket has been and mdash?
When an object - rocket or otherwise - rises, its kinetic energy gets converted to gravitational potential energy. At its highest point, if it rises directly upwards, all the kinetic energy will be converted to gravitational potential energy. However, its movement may also have a sideways component; in that case, not all the kinetic energy is converted to potential energy.
Why does a non energy saving light bulb give off more heat than an energy saving light bulb?
Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.

What is the amount of unusable energy in a system called?
The amount of unusable energy in a system is called entropy. Entropy measures the level of disorder or randomness in a system and represents the energy that cannot be converted into useful work.
